Ruiandsion Motorcycle Headlight Bulb Types BA21S BA21D Free Sample

To cater to the different needs of wholesalers, we offer two bulb bases: BA21S and BA21D. Here's a note on the differences between BA21S and BA21D: Similarities: Both bases have the same diameter size: 21mm (BA21), meaning they fit into the same size socket. Differences in Contact Pin Configuration: BA21S: It has two contact pins, one for the positive contact and one for the negative contact. This base design is typically used for simple electrical connections. BA21D: It also has two contact pins, but their positions and configurations differ. The BA21D base usually has a central contact point and two additional contact points located at the outer edge of the base. This setup supports more complex circuit requirements, making it suitable for applications that need a bipolar circuit connection.
