a little, common problem
 

condensation in one of my headlights. why does this happen?
and how do i get rid of it? i heard to use a hair dryer, but wont it just come back again? should i drill a little hole in the back of the housing for the headlight?

it happens due to difference of temperature inside and outside of the housing. most, if not all, headlight housings have moisture outlets in the back (i know 96-00 civics have two in each) so you dont need to drill any holes.

check if that L shaped rubber thingy on the hole is blocked by some debris or not. just park the car in some direct sunlight and the moisture should go away.

i would also recomend resealing around the headlight

OMG Kieran hi!!!! :wavey: :D

ya seal your headlight and check for leaks around the rubber gasket that goes around the wiring harness. don't drill any holes damnit, the headlights are supposed to be sealed.
