What happens when condensation builds up in a headlight?

Condensation inside your headlight is bad news. The buildup of moisture leads to premature bulb failure and can lead to electrical short circuit on certain models. Sure you could take the easiest way out and drill a drain hole in the headlight lens, but that just looks ugly and doesn’t solve the real problem.

What’s the best way to seal a headlight?

Wipe away any streaks with a dry cloth. Assemble the headlight. Apply a thin bead of clear RTV silicone to the mating surface on the headlight assembly. Exercise caution when applying the silicone — too much will cause the silicone to overrun into the headlight, but too little will prevent a good seal and lead to more condensation.

How do you install a headlight and bumper cover?

Press-fit the lens onto the headlight assembly and ensure that all locking tabs lock into place. Install the headlight assembly. Reverse the procedure given in your vehicle’s service or repair manual to install the headlight and bumper cover, if needed. Follow all torque specifications given for the headlight and bumper cover bolts.

Is it bad to have moisture in your headlight?

Trapped moisture can be dangerous, particularly for nighttime driving. Just like debris and fog on the exterior of your headlight casing, moisture trapped inside the seal can dim your lights or even create blind spots. In some states, you won’t pass your vehicle inspection with headlight fog.

Why do I have water coming out of my headlight?

In some states, you won’t pass your vehicle inspection with headlight fog. This could be caused by a leak in the seal around your headlight, which allows water to enter the space behind your headlight lens.

Can you break the seal on a headlight housing?

Breaking the seal between your headlight lens and housing is relatively easy, but once it’s broken, you’ll need to be very cautious to create a firm seal once you replace it. If you aren’t comfortable working with sealants, it might be worth bringing your car to a mechanic who is. Before removing the seal, check your headlight housing vent.
