I just salvaged the old broken map light fixture by replacing the switch, which was broken, with a plastic rocker switch from a 12V lamp from an RV trailer I used to inhabit. Had to use a bench grinder a little on the lovely chrome steel fixture and the switch, but with the LED 1157 bulb I used to replace the old burnt out 1004S, my efforts all bore excellent fruit. I then noted that map lights run beween $50-$65 on eBay, so I count myself well ahead. It throws plenty clean white light in the same direction the original was meant to. I expect it to last for decades....
