More light in the cabin was also needed, at least for me and my family. Nothing worse than dropping something in the footwells and turning on the map light only to find out the map lights suck.
I replaced them with 5630 SMD LED's. Bonus fact, 5630's are brighter per LED than 5050's and have a great light output. I bought some simple 24 5630 LED's with 31mm festoon adapters for the map light and cargo light, attached them with doublesided tape. For the map lights, I used 31 mm festoon style LED's with 6 5050's (5630's are too big), then added a jumper wire from the ground side of the housing to the driver's map light. I just threaded it through under the headliner using a coat hanger and had it pop out where the rear view mirror attaches to the roof. With the jumper wire in place, when you open a door the driver's map light turns on. If you press the driver's side map light button, the dome light comes on as well as the map light. If you press the passenger's side map light button, only the map light turns on. Perfect.
