This mod is very simple like the 350Z. There is plenty of room to squeeze in a board with an array of LEDs. I decided to use Luxeon K2 Star for this custom mod.
First, pry the inner edge (toward the center) of the map light cover. This side is beveled to make it easier to pry. There are 4 pegs total to pop out.
Pull straight down, not sideways.
The bulbs are
194 type like the license plate and trunk light, so you can simply swap them for an LED bulb. My custom K2 Star with BuckToot driver is on the left side.
Comparison picture. The drawback to LED is the hot spot in the center. It's not much of an annoyance since the light output is so much brighter and cleaner.
