i changed out my dome lights from one type of LEDs to these that are much brighter and more what i originally wanted... i also added a pieces of a mirror vinyl next to the lights over the plastic. thought it made sense but not sure how much more it will help... all pics were taken during the day but i can already tell the difference...
as someone else has posted i bought them off ebay, here is the link: 2X Bright White Color Car LED Dome Map Trunk Interior Light Panel Lamp Bulb W24A | eBay
the stock dome might be around 5w. the biggest t10 wattage ive seen is 15w. but the led is listed as .7w
