I have fog in my head light. What can i use to put a seal on the outside?

rtv silicone sealant, but first i'd take apart the light to make sure its all dry, then reseal it,

i made a how to in the exterior forum, check it out, the post is on clearing headlights


You'll never touch God's hand
You'll never taste God's breath
Because you'll never see the second coming
Life's too short to be focused on insanity
I've seen the ways of God
I'll take the devil any day
Hail Satan

there is also a spray that you can get from any parts store. all you do is spray it in and it will dry it out.
