What to Do if the Third Brake Light LED Stops Working

Video tutorial

The suggestion from the YouTuber is to reverse the wires between positive and negative if the third LED brake light does not work. However, this trick does not solve the issue, as LEDs are polarized, unlike incandescent bulbs.

Therefore, performing this action does not turn on the light; it simply remains off without damage, as the LED functions like a diode. Instead, first check the dedicated fuse, then ensure the wires are not broken or frayed (especially those near the tailgate).

If the wires are fine, replace the LED module (or, if you have soldering skills, the individual LEDs).
