Well, you're going to have to drill holes in the side of your car, where you want the sidemarkers. You have to avoid and make sure you're not drilling through anything important (wiring, sensors, interior paneling) and you need to make sure the side markers are mounted in the same location on both sides. You'll want the hole to be somewhere that you can see or get at the back of it for wiring and mounting purposes.

Once you get the holes, the sidemarkers are sometimes held in by bolts, or some sort of adhesive. You'll have to run wiring to either a switch, to your headlights, or your turn signals (depending on when you want your sidemarkers on).

You also need to make sure that your wiring job doesn't run on any metal, such as the hole you made in the side of the car.


I'd suggest some LED sidemarkers....
