My friend has a teg with fogged headlights. But it seems like its in the headlight. Does anyone know something about putting them in an oven????

 

Dont leave them in their to long or they will melt...obviously. U could use a knife also to cut through some of the glue, then try and pull it apart.

 

Get a cookie tray, lay some tinfoil down on it,
Put the lights in for around 6-8 minutes at 350,
just make sure you're watching them around the last few minutes.

Once they're done and out, gently pry apart the housing with a flathead,
have the metal clips off beforehand though, do the reverse for putting them back together.

 

If there's water condensation in the inside of the headlight, you just need to seal the seam between the lense and grey plastic with some silicon sealant. Let the headlight dry out first before sealing it (the inside). There's no need to take them apart.

 

Try a blowdryer!
