Carefully drill a hole using the drill bit included in the package. We recommend drilling directly in the center of the assembly, using the center raised portion as a guide line so the hole isn't misaligned. Try to slightly shave down four corners of the socket in small increments so the socket can fit snugly in the housing.

Install the socket into the housing. It should fit very tightly. If it is a little bit loose, you can apply some  silicone glue around the outer corners of the socket to create a tighter seal.

  • The color combo of the wires may differ among production batches, so we recommend that you double-check and test which wire is what function. You can easily test the socket by inserting the bulb and touching the wires directly to your car's battery. Mark which wire is the brighter mode, parking light mode, and negative.

  • Tap the negative wire from the socket to the ground and the black wire of the stock parking light.
