If you're looking to replace the weak incandescent glow of your car's map lights with something a big stronger, this tutorial outlines how to gut a cheap LED tap light to upgrade your interior lights.
Pete Mills wasn't a big fan of the old incandescent light bulbs in his car's map lights. When he searched for an LED replacement he was shocked that the going rate for the custom replacement bulbs was $US15 per bulb. Not about to pay $US45 for replacement bulbs he hit up the Dollar Store and bought a couple of LED tap lights for a buck a piece.
With some basic soldering he wired in the guts of the tap lights to the sockets in his car; now he's got bright and clean light from bulbs that will outlive the car. Check out the link below for lots of photos and a step by step guide to help you upgrade your car's interior lighting.
