I notice too that the light was not turning off right away when i was closing the trunk, it would take around 10 secondes to turn off. Also that little halogen bulb was not bright enought so i put a LED bulb instead. The later i was like.. still not bright enought.. so i decided to make a little upgrade. 2 LED strips, 1 on each side of that metal piece on top, and i just connect those to the hold halogen bulb wires. Now that's what i call having lights in a trunk when you are searching something in there!
also now all the wires are hidden nicely
