I figured since all the cool people run scale LED lights and I have an LED light bar on my JK, I should give in to peer pressure.
I bought a 6", a pair of 4" and a 2" light bars from Vanquish.
First crawler to get one was the Wraith, I already have the LED's in the light buckets with some reflectors I pulled out of a ball cap head light.
But since they work best on more than 11 volts, I bought some mini 3 cell Lipo packs which give out 13.3 volts at full charge.
The next 2 crawlers I have will also get LED's later next week.
