I've been lookin at leds for the dome and map lights. I've ordered from this site before so I figured I would check them out for car leds. I found bulbs similar to the ones being sold for over 30 bucks for the set for 5.83 total!
Here are the ones for the map.
and this one is for the dome.
I should note that I have not purchased these, but the reviews are pretty good. I ended up taking a gamble on some brighter and more expensive ones and hope my measurements are good. Just figured I'd post it to save peeps some money because its hard to go wrong at a price like this.
