Water droplets collected along the bottom of a headlight lens from the inside

When moisture inside is a fault

Many headlights are vented, so a light mist after rain or a car wash that clears once the lights warm up can be normal.

These signs mean water is getting in and staying:

  • Droplets or a puddle at the bottom of the lens
  • Fog that does not clear after a drive
  • Bulbs, LEDs or DRLs failing after wet weather
  • Rust or white residue on the parts inside

How to fix moisture in a headlight, and why drying it is not enough

A hair dryer, silica packs or pulling the back cap will dry the headlight for a while. Silicone smeared on the outside rarely reaches the gap that leaks.

The water came in through a failed seal, a blocked vent, a loose cap or a hairline crack. Until that path is closed, the next rain brings it back.

The water in headlight fix that lasts is to find that path and seal it from the inside.

Headlight seal repair, step by step

  1. Open and dry

    The lens comes off and the inside is dried completely.

  2. Find the leak

    Vents, caps, the seal and the housing are checked for the path the water used.

  3. Reseal

    The old sealant is cleaned out and a new seal goes on all the way around.

A headlight reseal goes after the cause, not just the water, which is why it is the fix for leaking headlights.

Damage the water leaves behind

Standing water can corrode connectors and LED boards and make reflectors peel. Those parts are checked while the headlight is open.

For burned or peeling reflectors, see Headlight Reflector Repair. Tell us about the damage and we'll confirm whether it can be repaired.
