Review on Optronics TLL190RK Combination Tail Light by Matt Lewis

I found very little information on this before ordering but I'm glad I took the risk. The headlights are very bright and well designed. Each light is an LED, unlike some that use an incandescent bulb for the side markers. I use them on a boat trailer and since installation they have been fully submerged in water maybe 5 times with no shorts or water infiltration issues. The only issues I've encountered are the location of the cable exit on the back of the case and the ability to properly ground these LEDs. The wire exit is easily repaired by drilling a new hole and rethreading the 8" wire. When grounding, make sure you have a clean bolt hole or nut contact surface (absolutely free of paint or rust). ).
