- 1). Use a flat head screwdriver to lift the protective lens off of the fog light. Pull off the seal around the light. Place sealant around the outside of the fog light. A silicone sealant works best as it provides the best structural support for the light.
- 2). Insert the fog light into the open light space on the Nissan. Hold the light against the bracket for a few minutes to allow the sealant to set. If you have chosen to install halogen lights, ensure you do not touch them with your bare hands as it could shorten the bulbs' life due to skin oils.
- 3). Connect the ground wire to the battery connections of your 2006 Nissan Altima. Ensure the cables are correctly installed to the right terminals and do not come loose when tugged slightly.
- 4). Turn on the engine and switch on the lights to ensure they are working correctly.
