Defective LED board

Even a single failed LED bulb in the LED board can cause the board to be disabled by the vehicle. If this happens, the error message will appear on the instrument cluster and for the duty of brake lamp will be delegated to fog lamp.

Replacing LED bulbs

The whole LED board unit is expensive. LED bulbs can be replaced by soldering.

1. Remove the taillight from vehicle.
2. Take the circuit board out, it is attached by one screw (see below).
3. Use a 12v adapter by connecting it to the circuit board and see which bulbs are damaged.
4. Remove damaged bulbs and install new ones using a soldering iron. Make sure the new led lights are positioned the same exact way the old ones were, otherwise they will not work.
5. Once this is done, you can insert the circuit board back into the car. Make sure prior to this all the lights are working.

You can buy square LED bulbs by using this keyword "LED 7.62MM 638NM ALINGAP RED CLR - LTL912SEKSA".
