The part number is 27450C (both sides), as far as I know this is the only 5x7 sold by Truck-Lite. I got it from Amazon and the seller was Drivetrain America. As of right now, if you search "Truck-Lite 27450C" on Amazon it appears as the first listing with the best price and an "Amazon's Choice" tag appended. Headlight Revolution (referenced in the video) also carries them online, but I've never used that company. I don't see a sales option on Truck-Lite's website, but they do have a "distributor search" option which may reveal a trucking or RV supplier that has these (and probably other brands) in stock locally.
Great video. By the way Truck Lite released a projector (non-reflector) version of the 5"x7". its the #37450. I am most likely going to get the 7" round version of it but need to make some sort of harness to run them
Truck-Lite makes a heated version. I’m curious how yours will work with heavy wet snow. Does it create the same amount of heat as the incandescent makes to keep ice/snow build up?
On the few occasions that I've been in wet snow/icing conditions with this vehicle, I have gotten buildup and had to manually clean the lenses. But with an automatic, no ABS, no traction control, and a lunchbox locker in the rear axle, I try to avoid driving it in those conditions :-)
