I thinking of buying a bunch of bulk LEDs and wiring in a few here and there. Most of the ones I see say they run off of 5 or 6 volts. How do I figure what resistance of resister to buy to drop the voltage down?

works great

remember to put 14volts not 12 as your altenator will prooduce around 14v at peak

You can wire a group of 6 in series and be at about 2-4 volts, which is right in their operating range. Like this:

If you use less LEDs make sure you add a resistor on the positive side before the first one or you’ll burn them out.

Good Luck.
