Added another trunk light bought it several years ago at the dealer parts dept. I found some high output led bulbs on Ebay now I can see what's in the trunk

Looks great and makes a huge difference!

 

The coupe has one light on the drivers side, and as it has no reflector behind the bulb half of the light is lost behind the panel.
I found that the LED licence plate light unit replaces it perfectly, just remove the original one, switch the connector and put it in the original hole. I added one on the opposite side for extra light.
I also added one in each footwell, so no fumbling for something you dropped at night, it is wired into the map light circuit. The bulb for the map light is also LED, these bulbs have the light directly facing the lens not sideways.
The LED footwell and trunk light mods can be found as .pdf files in my signature file.

 

I put one on each side and it really didn't help much when you have items blocking the lights. So on my coupe I install two more much higher. Way better now.
