Review on 🚨 16-inch 12 Red LED Trailer Light Bar with Brake and Sequential Turn Signal - DOT FMVSS 108 Compliant - SAE S2I6U2PS Approved - IP67 Submersible - Running Marker ID Rear Trailer Tail Light Bar for 80-inch Utility Marine Boat Trailers by Ken Coste

As mentioned, very bright. Seems strong. It is approximately 16" x 1" tall and less than 1" deep. This is a five wire light that connects to a typical four wire trailer circuit. You just don't connect the red wire to the headlight that controls the brake is. With this connection, the headlights work as follows: signal on the left, order of all 12 LEDs from right to left. It is quite obvious that you are turning left. When the parking lights are on, they still work. c) If you turn the right Turn signal on it works the same except for the left to right LED sequence of course d) Braking will light up all 12 LEDs Very well seen The only downside to this is that if you have either a left or right turn signal, there is no long turn signal on the light only a brake light Given that I couldn't find anything else small enough to fit in my bike rack this is Opera tion acceptable. Please note: when approaching an intersection, turn on the right signal, and this traffic light will change from left to right one by one. Then apply the brake and all 12 LEDs will light up. no more signal. You wait for the green light to come on, take your foot off the brake pedal and the light starts changing again.
