View Full Version : Outside Light Replacement with LED

A while back I was looking at replacing the tail lights, front turn signals with LED replacements.

I read this was going to require a flasher change since there is a vast difference in the amount of current the LEDs pull compared to their incandescent counter parts.

I'm more interested in the LED replacements for their low power consumption and length of life over the cool look.

With 4 100 watt KC off road lights and now 2 IPF high wattage head lights, any power I can save elsewhere will benefit me and my electrical system.

There are 4 bulbs in the turn signal indicators, up front, and 4 bulbs in the tail light (stop and turn signal)

If I start with the brake lights I don't have to worry about getting the LED turn signal, and I can just see how bright they are. I suspect they will be just fine, but I hate to spend a bunch of $$$ to find it isn't what I really wanted.

Someone check me, I don't really want to remove the housing. Is the bulb for the brake lights a 3157?

I'm looking at these...

The easiest way is to buy replacement bulbs like you showed there. Most of them are already set up with the right resistors to work with the stock system so you wouldn't need to switch flashers. I have led bulbs in my bike tail light and all four of my turn signals. only the head light isn't led.

Load resistors are bad. They increase the resistance of the LED (pack) to make it the same as the incandescent bulb. So the power usage stays about the same. The electricity is radiated in the form of heat. Power consumption is the same. Might as well stay with the regular bulb in this scenario. They sell load resistors and flasher relays that work with the lower power consuming LEDs.

What I need to do is find out the pin out, or type, of flasher I have so I can make sure I order the correct LED flasher. Oh and buy all new LEDs for the front and rear! lol looks like that will be about $150, no including the flasher. :sad0147:
