I only used the LED bar with 80 Epistar LEDs. I got this second hand pretty cheap and with the right length so I snagged it. I wanted the Cree versions but they're so expensive.
I'm driving the PT54 LEDs from a board I originally designed as a buck converter for an MPPT solar charge controller that I modified to run constant current with auto power control using the onboard LED thermistors to limit power when it heats up. Build details are here: 1200 lumen Rear Foglight
Man I wish I could build something like that. I would love the ability to have a backup light like that for in the woods. I also want a rear facing and forward facing light bar with two smaller side facing ones. But that's a bunch of money lol.
I only built the rear fog lamp the lightbar, I bought as a unit and just fabricated custom aluminum brackets to mount on the OEM bolts for the roof rails (that I didn't have on my car). Building a lightbar that big would take a lot of time and effort that I'm better off buying a ready made unit.
I need those tailgate lights on my car- there are a few giant douchey trucks around here that like to tailgate. They also havent thought to lower/raise their headlights, so they tailgate and blind you at the same time...I bet a few of those LED's would get them to back off real quick...
I mainly made it for those that tailgate with their high beams on. Most of the time, they get the hint and turn their high beams off and so I turn it off too. But there are those that won't dim their lights so I keep it on and they usually slow down and back away.
I just had one slow @ssh0le on the passing lane that won't move. Turned the lightbar on and still won't move so I passed him on the right. When I was in front of him, he turned the high beams on his cheap drop in HIDs on me so I turned the PT54s on. He dimmed his lights instantly and backed off.
I was recently conned into buying a Mazda B4000, which is actually a Ford Ranger in disguise. It is
complete will all the usual Ford trappings, designed and built to a price by people who don't care. I will
never forgive Mazda for what they have done to me. Luckily I can fall back on a scooter when it's warm
enough. The truck is probably going on Craigslist. So watch out for that.
Building it isn't too hard. Just need a bit of time molding the plexiglass case to fit the bumper. Or you can cannibalize a stock rear foglamp housing. The only hurdle is the heatsinking needed by the LEDs.
