I put two sets of T5 high output (not just regular t5) fixtures in mine then cut a simple metal wire cage around them both. Forty bucks a piece, very very bright at night
I'm down a good two miles of terrible dirt roads. Never a problem. Probably could find a good LED substitute, but these things are bright man. I just daisy chained two sets together and threw a switch next to the factory light switch by the door.I thought about those but was worried the bulbs may shake and vibrate out... out roads are horrible so I was a little skeptical of fluorescent lights
