I wanna open my headlights and paint the bezels black. Anybody ever do that? I pulled the lights today and put them in the oven at 200 degrees for 20 minutes. Wouldn’t budge. I’m nervous to try hotter and I don’t want to cut them open. Any advice? ( other than buy aftermarket headlights). Thanks!

I’m almost positive GM uses permaseal on the headlights and it will be almost impossible to bake them open. I have heard it *might* be possible if you use low heat and extend the time in the oven substantially. You could run the risk of melting other parts of the housing though. I will be doing a retrofit this weekend and I ended up ordering some OEM style aftermarket lights that I could just bake open. That way, if I screw anything up, I didn’t ruin my stockers

OEM headlights are not sealed with material that can be baked open from my understanding. This works for the aftermarket ones…but the OEM have to be cut open.

Yeah, all the ones I saw for Silverados involved cutting them open which I’m not real fond of doing. I’ll probably just get some aftermarket headlight housings that have black bezels at some point I just am leery as a lot of reviews on most of them complain of fogging up and condensation.

Does anybody have recommendation on housings that don’t fog up?

If you want aftermarket housings I have a set I’d sell you if your interested. I will tell you with aftermarket housings you get what you paid for. The light output is terrible in cheap aftermarket headlights. Depending on what you buy. I cut mine open. I was super Leary about doing it. Finally did it roughly a year ago and haven’t had any issues with them since. Take your time and they’ll turn out. Just seal them up real good and you’ll be fine.

Also for anyone else that wants to do this the retro fit source recommends for perma sealed headlights 285 degrees for 23 minutes in the oven. For butyl rubber sealed ones 270 degrees for 7 minutes. I will post back because I have a couple sets of lights for my truck. I’m going to try baking open a set to add drl switchback strips and painting the housings. I do have a set that I’ve already cut open but I found another set that were brand new locally for $100. They are gm oem ones too so I couldn’t pass on them.

I tried aftermarket headlamp assemblies with clear side marker lenses because I wanted switchback bulbs to match my tow mirrors. They were cheap and appeared well made, (EBay, $140,) but wasted money. Headlamp bulbs didn’t project/diffuse/disperse the light properly and they wouldn’t adjust up or down. I recycled them. Bought a lightly used set of 2014 OEM assemblies for $95 recently and I plan on experimenting with them….

I’ve also heard that there are companies that will do it for you if you send your headlamp assemblies to them. Don’t know what they charge, but heard there’s a place in Missouri.

Yeah one company is fast headlights. I’m just going to do it myself. I too bought a set of cleared lights off eBay for around $140. I had the same problem you had with them. They now are parts pair lol. I also have a pair of oem ones that I cut open and cleared. Picking up the other set tomorrow.
