So does this LED bar light up three individual lights for the running lights and all the way across for brakes? Does it have a DOT approval number? I would not have thought it was accepted to have the space between the clearance lights lit up (even when braking), but I'm certainly no expert on vehicle lighting standards.
At any rate, it's an interesting sounding unit. I would suggest sealing the screw holes (and what looks like a saw kerf) where the old lights used to be as soon as possible lest you have water getting in and wrecking havoc.
