To dry the headlights, remove the back cap and let them air out. You can speed up the drying process by using a heat gun, air tool, or blower to blow air inside the headlight. Alternatively, you can also park the vehicle in the sun with the back cap removed for 24-48 hours.
Step 2: Check all Caps and Covers
Take a look at all possible openings to the headlight, make sure all bulbs, caps and covers are correctly seated. If they are not. remove the moisture and correctly seat them and see if the mositure returns.
Step 3: Reseal the Headlights
Inspect the seal for any openings. If there are openings or cracks that allow for moisture or water to enter either reseal the headlights or use additional sealant to make watertight. For headlights that were cut open, we recommend resealing around the entire seal with RTV Silicone Sealant, which can be found at your local hardware store. For headlights that were baked open, simply rebake the headlight in the oven and press it together firmly.
Step 4 (Optional): Install Breather Patches
Once the headlights are completely dry, you may optionally drill a small hole in the bottom of the headlight and install Breather Patches to cover the hole. These patches allow air to flow into the headlight while preventing moisture from entering.
