yea... it gets pretty dam hot like!!!
was just wanting to put in a different more white light perhaps... the one thats in is dulling down a bit with the typical yellow... so it will need replaced soon anyways.. just wouldnt mind a whiter crisper colour... like Led sidelights for example that kinda look ???
Youl be ok with leds, at the end of the day anything that gives off light will be fine, finding the right size wont be easy though. If i was you id just get a led interior light and modify the lamp holder to fit.
Mite be worth taking the measurements of it and scouting ebay for a led unit with the same sort of connection. I dont know wether it is a screw in or its just held in place with 2 contacts. If its held in place with the 2 contacts youl be able to manipulate them a bit so it will hold the leds. Any type will do, its only 12v.
