How to Repair LED Brake Lights
- 1). Park your vehicle on a flat and level surface. Apply the emergency brake. Turn off the engine.
- 2). Inspect the brake light to determine how to access the LED bulb. Depending on the make and model of your car, you will either be able to remove the lens cover from the outside or you will have to access the bulb from the interior of the trunk. If you see a pair of screws on the outside of the lens, simply remove them with a screwdriver and access the bulb. If not, continue to the next step.
- 3). Open the trunk. In the case of a truck, pull down the tailgate. Pull back any carpeting, bed lining or plastic access panels covering the rear of the taillight assembly. Note the electrical cable coming from the light. Depress the tabs on the plug and separate it from the light assembly.
- 4). Pull the assembly a few inches into the interior of the vehicle so that you can grasp the LED bulb cluster. Turn the bulb to the left to remove it from the socket. Bring the burned out bulb to an auto parts store to purchase a replacement bulb of the same size and style.
- 5). Insert the new bulb, turning it to the right to secure it in place. Reverse the above steps to reassemble the brake light.
