Advantages of Exterior Bulbs
 

 

Improving safety

The main function of turn signals is to enhance the safety of drivers and other road users. When the driver turns on the turn signals, they will emit bright lights to inform other drivers of their driving intentions, which helps to avoid traffic accidents.

 


Increase visibility

Exterior bulbs are particularly important at night or in situations with poor visibility. They can greatly enhance the visibility of the vehicle, making it easier for other drivers to notice your vehicle and avoid collisions.

Provide clear instructions

Exterior bulbs flash to clearly indicate the direction of vehicle travel, allowing other drivers to clearly understand your driving intentions and make appropriate responses.

Compliance with traffic regulations

In many countries and regions, the use of turn signals is a part of traffic regulations. Using turn signals not only helps you avoid traffic accidents, but also ensures that you comply with traffic regulations and avoid fines or other legal penalties.

Improving driving efficiency

Turn signals can help drivers predict the driving intentions of other drivers more accurately, thereby improving driving efficiency and reducing traffic congestion.

Bulb Type and Compatibility
The first and most crucial consideration when buying exterior bulbs is the bulb type and compatibility. Not all vehicles use the same type of turn signal bulb, and it's essential to ensure that the bulbs you choose are compatible with your vehicle's make and model. Common turn signal bulb types include 1157, 3157, 7443, and more. Consult your vehicle's manual or check the existing bulbs to determine the correct bulb type. LED blinker lights offer a modern and efficient solution for your vehicle's signaling needs, ensuring you stand out on the road.

 

Bulb Brightness
The brightness of the exterior bulbs is measured in lumens. The higher the lumen rating, the brighter the bulb. When selecting exterior bulbs, consider your specific lighting needs. A brighter turn signal is especially crucial for increasing visibility in challenging conditions, such as inclement weather or bright sunlight. Opt for bulbs with an appropriate lumen rating to ensure that your turn signals are clearly visible to others on the road.

 

Color Temperature
Color temperature, measured in Kelvin (K), affects the perceived color of the light. While most exterior bulbs emit an amber light to meet legal requirements, it's essential to select bulbs that match your vehicle's specifications. Bulbs that deviate significantly from the standard amber color may not be street-legal, so make sure to check local regulations and vehicle requirements.

Beam Pattern
The beam pattern of a exterior bulbs bulb determines how the light is distributed. A well-defined and focused beam pattern is essential for effective signaling. It ensures that the light is evenly distributed and easily visible to other drivers. Consider exterior bulbs with a precise and uniform beam pattern to make your intentions clear to everyone on the road.

 

Durability and Lifespan
Durability and longevity are crucial factors when buying exterior bulbs. You want bulbs that can withstand the rigors of everyday driving and provide reliable performance. LED turn signal bulbs are known for their long lifespan and resistance to vibrations, making them a durable choice. Be sure to select bulbs with a reputation for reliability to minimize maintenance and replacements.

 

Ease of Installation
The ease of installation is an essential consideration, especially if you plan to replace the bulbs yourself. Some exterior bulbs feature a plug-and-play design, making installation straightforward and accessible even to those with minimal automotive expertise. Review the installation process for the bulbs you're considering to ensure it aligns with your skill level and tools available.


Brand and Quality
When buying exterior bulbs, consider the reputation and quality of the brand. Well-established and trusted brands often offer high-quality bulbs with better performance and reliability. Research customer reviews and ratings to gain insights into the experiences of other vehicle owners with the same bulbs.

 

Heat Dissipation
LED exterior bulbs generate heat during operation, and efficient heat dissipation is essential to maintain performance and extend the bulb's lifespan. High-quality bulbs often incorporate advanced heat management systems, such as heat sinks and fans, to prevent overheating.

 

Price and Warranty
While price is a consideration, it should not be the sole determining factor when buying exterior bulbs. Opt for bulbs that offer a balance between cost and quality. Keep in mind that investing in higher-quality bulbs may result in longer lifespan and reduced maintenance costs over time. Additionally, consider whether the bulbs come with a warranty, as it provides added peace of mind and protection in case of defects.

 

Local Regulations and Requirements
Local regulations and requirements can vary, so it's crucial to understand the specific rules governing exterior bulbss in your area. Ensure that the bulbs you choose meet all legal requirements and are street-legal to avoid potential legal issues or fines.

Why You Should Upgrade to Exterior Bulbs

 

As we all know, turn signals are how you communicate with other motorists on the road. You use them to make known your intent of either changing direction, changing lanes and sometimes when you want to overtake. It is therefore absolutely crucial that your exterior bulbs are in good working order as they play a big role in preventing accidents.

 

One of the simplest ways of telling whether one of the exterior bulbs is damaged is by the fast blinking of the signal indicators located on the dashboard. This is brought about by the less electrical load.

It's quite obvious now that if your car still has halogen bulbs, you need to quickly switch over to LED car lights. This is especially true with the exterior bulbs. Most of the LED exterior bulbs are situated either at the side or much further down than other LED auto lights. This makes them prone to damage from getting knocked by objects.

 

That is...if they were not built to last. Incandescent bulbs will quickly come to the end of their life if they are broken. LED exterior bulbs can withstand a lot of external pressure which makes them durable. You save on your cash as well as you do not have to replace them regularly. And you've got to admit how sleek the car looks with those LED exterior bulbs on. It will definitely raise your car's aesthetics.

One great benefit of exterior bulbs is that they are bright. This makes it that that much easier for you to be seen by the other motorists allowing them to give you way or act accordingly.

 

The high number of vehicles in our cities means that there will almost always be a time when you are stuck in traffic. One of the easiest ways to collide with another car is when your exterior bulbs cannot be seen clearly. The fact that LED exterior bulbs are bright makes them simple to spot. This allows you to maneuver easily through the other cars which will also help you get to your destination quicker.

An important component that goes with installing LED exterior bulbs is load resistors. Without these resistors, also called equalizers, you may soon find your lights flashing as if being possessed. The last thing you want is to be stopped by the traffic police.

 

The flashing is brought about by too much charge reaching the LED exterior bulbs. For an LED to work at its optimum, the charge needs to be within the limits that the LED can handle. Too much voltage and the LED car lights would get burnt. This is why it is important to add a load resistor.

However, this is not a rule cast in stone and there are ways you can bypass the need to use a resistor. If you can lower the input voltage to the same level as the forward voltage on the LED, then you are set to go.

 
Maintenance Tips for Exterior Bulbs
 
 

Choose the Right exterior bulbs
Different environments may require different types of exterior bulbs. As a result, choosing the correct brightness, wattage, and color temperature is essential. For example, certain LED lights are suitable for office spaces, while others work better in industrial areas.

 
 

Regulate the Temperature
Although LED exterior bulbs stand up better to hot temperatures than other exterior bulbs, you should still maintain a cooler temperature around them. If you expose your exterior bulbs or fixtures to higher temperatures, they may start to lose efficiency and burn out. Many LED exterior bulbs can withstand temperatures of up to 185 Fahrenheit before failing, but you should try to ensure they don't come close to that.

 
 

Reduce Humidity
Another essential LED lighting maintenance tip is to watch the humidity levels. Excessive moisture in the air can cause lasting damage to the electronic components inside the exterior bulbs. When working in humid workspaces, ensure there's proper ventilation and a dehumidifier if necessary.

 
 

Clean Them Regularly
One of the largest advantages of LED exterior bulbs is their longevity. However, because these exterior bulbs can last for years before they burn out, many people neglect to clean them and the areas around them. Built-up dust can short out your exterior bulbs and cut their lifespan, so remember to perform an annual or semi-annual cleaning of your light fixtures to protect your exterior bulbs.

 
 

Inspect Them Routinely
When performing maintenance, getting regular inspections of your lights is always a good idea. A licensed technician may help you determine if there are any issues with the electronic components in your exterior bulbs or if you need to adjust the wiring in your fixtures.

 

 

How Do Exterior Bulbs Work?

 

 

An exterior bulbs produces light by passing the electric current through a semiconducting material—the diode—which then emits photons (light) through the principle of electroluminescence.


This essentially means that a material (in this case, the diode) casts light when power is applied to it, hence the phase light emitting diodes. Electrons jump from one side (an electron-full side) to another (an electron-deficient side) across a junction (the “p-n junction”). Think of it this way: When power is applied to the p-n junction, the side lacking in electrons wants to be filled up with the charged electrons from the other side, and when power is applied the electrons get eager to move. During this process, light is created.


In contrast, an incandescent light bulb works by passing electricity through a small wire, or filament. The electrical resistance of the filament causes it to get so hot that it glows, producing light.
The fact that exterior bulbs do not rely on heat to produce its light means it runs cooler and is much more energy-efficient than an incandescent light bulb.

FAQ
 
 

Q: Will an LED bulb work if wired backwards?

A: Will a led work in reversed polarity? No, it will not light up. And LEDs have a low reverse breakdown voltage, so it may avalanche and be destroyed. The higher power white LEDs manufactured for lighting applications often have a reverse diode integrated with them as a safeguard against reverse breakdown damage.

Q: Are LED reverse lights worth it?

A: Illumination improves with LED reverse lights, giving the driver improved vision and faster response time when danger awaits.

Q: Can LEDs be installed backwards?

A: LEDs must be installed correctly or they may be damaged. This is because they are diodes and only allow electrical current to pass in one direction, thus they must not be installed backwards.

Q: What happens if we put LED in the reverse direction?

A: Will a led work in reversed polarity? No, it will not light up. And LEDs have a low reverse breakdown voltage, so it may avalanche and be destroyed. The higher power white LEDs manufactured for lighting applications often have a reverse diode integrated with them as a safeguard against reverse breakdown damage.

Q: Do LED bulbs have a positive and negative?

A: LED polarity
For an LED to work it needs to be connected to a voltage source with the correct side. The voltage supply side of the diode is the positive (+) side, this is called the anode. The negative side is called the cathode.

Q: Where should you not use LED lights?

A: LEDs deal with heat much differently than other bulbs. They use a heat sink to draw heat away from the diodes, as excessive heat can cause the bulb to fail. This problem is exacerbated when an LED light is installed in a ventless enclosed fixture.

Q: What is the reverse button on LED lights?

A: pressing this button always reverses the direction of lighting of the LEDs. After the first press on the 'reverse' button, the sequence thus becomes 3 – 2 – 1 – 3 – 2, etc. After another press on the 'reverse' button, the sequence is again 1 – 2 – 3 – 1 – 2, etc.

Q: Do LED bulbs get hot?

A: LED bulbs do get hot, but the heat is pulled away by a heat sink in the base of the bulb. From there, the heat dissipates into the air and the LED bulb stays cool, helping to keep its promise of a long life. And therein lies the problem: The bulb needs a way to dissipate the heat.

Q: Why do my LED lights burn out so quickly?

A: LED lights are designed to last for a long time, so it's normal to be frustrated when they don't seem to survive as long as you'd expect. Several factors can cause LED lighting to burn out quickly, from improper wattage and voltage to environmental conditions that can cause corrosion and overheating.

Q: Why do LED lights go out so quickly?

A: Unlike incandescent light bulbs, LEDs don't produce light using heat. This is part of what makes them so energy efficient. The downside is that their components can be sensitive to overheating, which can cause them to burn out prematurely.

Q: Do LED bulbs really last 10 years?

A: To put this stated lifespan into perspective, it means that, if you do choose us as your supplier of a new LED bulb, you could find yourself regularly using it for more than five years. In practice, this bulb could even near or exceed a 10-year lifespan depending on how often the light is used.

Q: Is a reverse light the same as a brake light?

A: Brake lights are red and activate when a driver applies the brakes, signaling to other drivers that the vehicle is slowing down or coming to a stop. On the other hand, reverse lights are white and illuminate when the driver engages the reverse gear, indicating that the vehicle is about to move backward.

Q: What is the difference between 3157 and 7443?

A: The 3157 and 7443 bulbs have different base designs that are not interchangeable. The 3157 has a W2. 5x16D base while the 7443 has a W3x16d base. This difference in the base shape and size is the main reason why the two bulb types cannot be substituted for one another.

Q: How do I know what brake bulb I need?

A: You can also look in your vehicle handbook in the lighting section of the manual. If you don't have your registration number or vehicle handbook, you can identify the replacement bulb you need by removing the old one. You should be able to see the bulb's application number, which might begin with a D, H or P.

Q: Do all cars have white reverse lights?

A: These lights are usually white and bright enough to illuminate the space directly behind the car. Vehicles are federally mandated to have at least one reverse light.

Q: Can you drive without a reverse light?

A: At least one reversing light must be fitted and in good working order otherwise it's a MOT failure.

Q: Is the reverse light and brake light the same?

A: Brake lights are red and activate when a driver applies the brakes, signaling to other drivers that the vehicle is slowing down or coming to a stop. On the other hand, reverse lights are white and illuminate when the driver engages the reverse gear, indicating that the vehicle is about to move backward.

Q: Do all cars have 2 brake lights?

A: Brake lights are a vital safety feature, without which our roads would be chaotic and very risky to all. However, until the nineteen eighties, cars were legally required to have only 2 brake lights. To explore the advantages of the third brake light, here's a brief trip down memory lane to see why cars have them.

Q: Do brake lights have to be red?

A: The light color designation for motor vehicles in the United States is established by the Federal Motor Vehicle Safety Standards (FMVSS) which is codified in 49 C.F.R. 571 (Code of Federal Regulations). That code requires that brake lights and tail lights on U.S. motor vehicles be RED in color.

Q: Can I put LED bulbs in my tail lights?

A: Looking for a cool mod you can accomplish in less than an hour? Try replacing the old incandescent taillight bulbs in your car or truck with state-of-the art LED bulbs. Any DIY enthusiast that can handle a screwdriver can complete the task with minimal effort.
