Opening H4 Housings

[qh187]

Does anybody know how to do this? I'm looking to open mine to reseal them. I have the glass lens ones.

i found it easy to do with a hair dryer. it should be one that can get fairly hot. i just went around the edges of the lense with the hair dryer heating it up. then i pryed it off with a pretty thin screw driver. you can also use a knife to pry the lense off. but you must make sure that the glue that holds it in is heated up and going to let the lense come off easily. gotta make sure of that because you can crack the lense when prying it off if you havent heated it enough.
