I used T-taps, but I took them out and just returned them. I was not impressed too much. Certainly not as nice as the front sequential turn signals. Also, the lack of reflectors; this is a DOT regulation. Imagine your car broke down on the highway at night, there would be no reflectors on the back for cars to see approaching your vehicle. Could not justify in my personal opinion.
I tried to install mine and it didn't work like I hope. I don't have the same wiring from car..
So far, I wired:
Red to red
black to black
Yellow to green/white
Green to brown
I got turn working. However, it seems like when it brakes, it turns on the low light when you turn on the lights, and when I turn on the headlights, it glows like I am braking.
When I have the head light on and brake, I don't see it glow brighter. Any help?
