LED lights are a popular aftermarket option for most vehicles as they are brighter-than-normal halogen bulbs and last a lot longer while using less power. The problem with installing LED lights on your vehicle is that you cannot simply swap out the bulbs. You actually need to replace the entire light assembly. The two most common lights that are converted to LED are the headlights and taillights. In order to do so, you must remove the old headlight/tail light assembly and install the new LED assemblies.

    Turn the vehicle's engine off and open the bonnet.

  2. 2

    Disconnect the electrical connection harness from the rear of the headlight assembly. Some vehicles require you to remove a rubber seal or cover to access the connector.

  3. 3

    Remove the fasteners securing the assembly to the engine compartment. Most vehicles have screws that can be removed with a Phillips screwdriver, but others have bolts that need to be removed with a socket wrench. Pull the assembly out of the engine compartment.

    Install the LED headlight assembly and reinstall the fasteners. Reattach the connector harness and the rubber seal/cover if necessary.
