Dust in headlights is it normal?
I washed my car recently and I noticed that there's some dust in the headlights (xenons). Is this normal? Aren't they supposed to be hermetically sealed? Obviously I've never messed with them. Thanks.

I believe the light units do have vent holes to get rid of condensation. They are not sealed. Mine sometimes get a little condensation and I asked dealer who said its quite normal to get a little condensation but this should disappear soon after the lights are activated.

I don't have any dust but both lights have had condensation when the car was hot and the rain was cold and once when I hand-washed the car. It dissipates quickly with lights off and very fast with the lights on.
