Pyroinsa stole my thunder, I did mine the same way. and as far as taking the bulb out before it gets too hot, I dropped the back seats and crawled in from the cabin so that the light wouldn't turn on. as for the strips, I just went to autozone and grabbed two blue LED strips and wired them into the old wiring, now when I shut my trunk, the LED's shut off as well, no extra wiring involved. It took me maybe 20 minutes all said and done.
