I just ordered this one:
AmazonGood price, I have a brush guard on my truck and had a couple of lamps on it that didn't survive the Needles. I think this unit will fit right in between the two vertical bars on the brushguard.
These are one of the highest rated on Amazon that don't cost $300. I'm a like unsure of what wattage my truck can provide. I have a heavy duty alternator.
BTW my truck was way too long for some of those rock crawling roads in Canyonlands. The 12 inch rock steps were the final straw. I had to get out and build a rock ramp to get back out after one of those...heh.
