I have a crack in my passenger side headlight it is only vicible when hood is popped, not leaking in any moisture yet but is a long crack, what do you guys suggest to seal it so nothing leaks in, i don;t want to get a new headlight really just due to the price and the headlight is only a year old anyways so lense looks great

 

use some 3m sealant. thats what i used and still good.

 

any more specific of what it is called i am sure 3m makes a ton of stuff or describe the packaging> not trying to be rude just want to get the right stuff haha

 

the diy windshield crack repair kits work well too. u want to apply pressure to get the sealant in between the crack itself.
