What Bulb is in Harley Tail Light?

Harley-Davidson motorcycles use a variety of different bulbs in their tail lights. The most common bulb is the 1157, which is a dual-filament bulb that has a bright filament for the brake light and a dimmer filament for the running light. Other bulbs that may be used include the 1130 (a single-filament bulb that is brighter than the 1157), the 1142 (a dual-filament bulb with a slightly different configuration than the 1157), and the 12V/21W (a single-filament bulb that is even brighter than the 1130).

Can You Replace a 1157 Bulb With Led?

Yes, you can replace a 1157 bulb with an LED. There are a few things to keep in mind when doing so, however. First, make sure that the LED is compatible with the socket type of the 1157 bulb.

Second, check the voltage and amperage requirements of the LED before connecting it to the 1157 socket. Finally, be aware that some LEDs may not be fully compatible with all functions of a 1157 bulb (such as brake light or turn signal). If this is the case, use only those LEDs that are specifically designed for compatibility with a 1157 bulb.

There are three different ways to wind a filament, and the 9003 is wound in such a way that it produces more light than other bulbs.

So, if you’re looking for a bulb that can be used for both high and low beams, then the 9003 is a good choice. Just make sure to get one from a reputable brand so you know it will last.
