What is the correct temperature/time combo for headlights in the oven?


    i’ve been looking for some concrete info on how long i should put my headlights into the oven in order to loosen the glue so i can take the housing apart.

    i’ve seen any where from +61404532026 and anywhere from 5 minutes to 15 minutes. i’m not really sure what temp/time combo i should go with. can anyone provide some concrete info on that for me?

    would i bake both headlights at the same time or do them one at a time? i would think one at a time since the other would cool by the time i got it apart.

    it also sounds like i need to place the lights on a wooden rack just so they aren’t directly on the oven grate.


    i think it depends on what type of headlights you are using, oem vs aftermarket.

    a good example, is with +61404532026 chevy silverado headlights. their oem headlights were hard for me to open. i had them in the oven for almost 20 mins at 275, and it barely made the adhesive soft. i had to combine that with the use of a heat gun to slowly pry it open, the entire task almost took an hour. aftermarket was a completely different story. it was only 250 for about 8 mins for one headlight, and the other headlight i didnt use the oven and just used a heat gun and heated the edges evenly for a few mins while constantly try to pry it open. that only took about 5mins. both cases with the aftermarket lights, i didnt have to use force to pry the lights, it just came right off because the adhesive was very elastic.

    i guess you could try it in the oven at 250 for about 5 mins and test it, if it doesnt work, try it again but for a little longer or at a higher temp. you should always keep an eye on it to make sure its not melting or anything. you definitely want to do 1 at a time, and on a piece of wood because the metal rack will melt any plastic. i used spare pieces of 2×4 and even plywood when i was putting them in the oven.


    good to know about the difference between aftermarket and oem. i will be using a set of aftermarket oem style for these. i might give it a go with the heat gun and light prying at first to see how it goes before even trying the oven.


    well not sure if it really depends…. but i go on the safe side. i do 200-225 degrees for 1 hour lol. hot enough to melt the glue, but not hotter than the bulbs get, and long enough for the heat to soak all the way through the glue. the light falls apart.


    oh man, 1 hour long? i bet that wood smell stays in your oven for a long time, hehe


    i do 300 degrees for 10mins then start prying it apart. if the glue isn’t hot enough, i just put it back in at the same temperature for another 2-3 mins and try prying it apart again.

    wow, you guys are daring.
    i put mine in at 170 for 10 minutes and use a putty knife to get them open.

    sometimes i’ll use a heat gun.


    i had some very strong grey glue in mine. i actually had to go to 325 for 20 minutes before it even started to soften the glue. 275 wasn’t doing a thing even after an hour, 300 didn’t even after a half hour after the 275 for an hour.


    i’ve always had good luck at 220 for 12 mins @ 3000ft elevation. i think it depends on how old the oem’s are too. most of the oem’s i’ve done are only a few years old except for s2000’s. my lord an hour @ 275 then 300 wow.
    i also put mine on an old metal cookie sheet…..no wood.


    yeah i don’t use wood… i use the metal cooking sheet. but the plastic etc fumes sure do drive the family away lol.


    i used 230f and 13 mins for my civic headlight.

    for my past projects, i used 200-225f for about 7-10 minutes.
