LED Lighting Question

Ok, I'm just finishing up the rear end with 4, 10" LED lights(2 on each side). I need to make them, running lights, turn signals and brake lights. Can I put a resistor on them and make the running lights at say 6 volts? Will an LED light work when running under 12 volts and be dimmer?

If I can do that I will use all 4 lights @ 6 volts as the running lights. The bottom lights at 12 volts will be the brakes and the top lights @ 12 volts will be the signals.

Any help would be great, I'm just finishing up the painless and this is one of the last things.

Yes but I cannot say at what voltage they will not light up any more....the best way is to get a variable potentionometer( a volume knob, that starts at no resistance and ramps up from there, and then turn the knob until the lights are the right output for driving lights, then use a multimeter to read the resistance on the knob and buy resistors of that value, and around 10 watts I assume.

cant u wire them up to the stock harness because that would give u everything u need.

No, it sounds like thay are 2 wire leds...and you have to reduce the voltage to get the lower light output.

so power and ground right? thats all there is to werk with?

does anyone make a 3 wire LED?

Yes, there 2 wire. What do you do for the reverse lights? Or do you just not run any? I was looking at the wires tonight thinking of a way to have them just to stay legal.

Check out FBI, they have a unit that you can use to wire up to your harness. It will give you all you need for driving lights.

avs also has a box that will make an led do what you are wanting. half throttle for parks and full throttle for brakes or turn (you know what i mean)

I run silverstarcustoms LED's right now in my truck, they are 4 wire, running brake are red, turns are yellow and reverse are white....but I am making my OWN PCB LED tails next time around.
