Review on 🚦 Partsam 2PCS Red 15" 11 LED Trailer Light Bar: Sealed Stop Turn Tail Park Third Brake Light - Waterproof, for Truck Trailer Marker ID Bar by Robert Aan

I installed these lights on the boat trailer rail of the light gheenoe trailer (see photo). It would be easier if there was a schematic showing which bulbs are for which function. There is a white, red and black wire. No label, no written instructions in the box. White - general / main / negative. After some trial and error, mostly errors, the red should go to the turn signal. It will be yellow/left and green/right. The black cable goes to the parking light. That may be the standard somewhere, but not in my area. When the daytime running lights are on and the turn signal flashes, there is hardly any difference in brightness. It will probably be more visible in the dark. When the running lights are off, the turn signal actually flashes the left or right brake light, so it's very obvious. Maybe this will save someone a headache. These lights mount through a hole a little over 1/2 inch in diameter, maybe 1.5cm. I drilled a 1/2 inch hole and reamed it a bit and then sealed it with caulk.
