Taking the light off wont be the hard part, taking the lens off of the light assembly will be a prick, thats if its what your gonna do.
Best to have a hair dryer & a bit of patience to warm up the glue seal so its easier to take apart. Maybe the oven trick would be a better option
Id try sourcing a second hand headlight assembly, might be easier?
Cheers,
