Dont put in oven.. Go buy a heat gun and start from the bottom with a flat head heating it up slowly.. It will take about 45 min, do not rush perfection..

I disagree... I think the heat gun method has greater potential for error, especially if it's your first time.

First, make sure your lights will fit in your oven without touching the sides or the heating element. Then, heat oven to 250, place your lights on a cookie sheet and bake for 15 mins. That heat is too low to melt anything but the factory sealant. Once out of the oven, take out the screws from the outer rim, can't remember how many, but just search along the seam for them. Then, have a friend hold the black plastic base while you pull the clear lens forward and up. It will be helpful for you and your friend to have gloves.

It seems scary, but it's not that bad. If the gooey stuff holding the lights together doesn't come apart fairly easily, put them back in the oven for 5 mins at a time.

Good luck.

p.s. search the DIY area for blacking out headlight threads, there are a couple in there that I know of. I would recommend against the "wet cardboard" method, it's just not necessary if you do low heat (250) and longer time.

HEy how easy was it using the 250 oven method. Been wanting to open my lights but am afraid I will melt the things. Also reading the DIY, they always recommend using wet cardboard.

Use the oven...I just did it this past weekend. the oven makes it so easy and when your done pop them back in for 5 minutes and they settle right back in the factory silicone add some more though. Ive researched and researched the heat gun offers a much bigger window for error and at least with the oven the entire unit is being heated which makes it easier

Very easy I must have done it almost a hundred times of course not the same headlight though.
