ive done this a few times to head lamps, its difficult, time consuming , but well worth it, i loved the way they looked. although , i dont beleive i will put them inside the headlamp anymore for one reason , the heat coming from the head lamp will eventually kill the leds,but if you place them on the outside they will be fine , great job by the way, the final product looks SUPER clean. ive dealt with LED alot , at least i would hope so, i own my own LED lighting company hahah
