easy to open onli. Use the heat gun, set to about 200 degree celsius, heat it up thoroughly at the glue part, then slowly use screw driver to pry open at the grill part (not the signal part). Also remember to reheat when its not hot enough, dun forget the clip too, the clip there need to heat up hotter so it will be soft and won't break when u pry cos its plastic material.
before reseal, heat up both part the cover and housing glue then close it. reheat again and slowly push until tight. Its waterproof liao, no need additional glue.
No need oven lor, my house also dun have oven, summore i feel use oven dangerous cos heating up the whole unit, the clear cover is polycarbonate ler, cannot withstand to hot, summore dunno got side effect if heat up the reflector part or not. I do the Perdana headlamp so long also where to find home oven big enough
