I am not big on cosmetic enhancements of vehicles but I do minor ones ever now and again. Here is my recent install of a 20 piece super bright LED board in my Cavalier. I swapped out the stock bulb because it was so dim I could never find anything in the centre console without my phone's flashlight to assist. A while back I installed a single super bright LED for the license plate. Next LED swap will probably be the signal lights and the high brake light.

I literally just swapped my dome light and sunroof map lights out to some really white LEDs. makes finding things in the cup holders so much easier because i keep random crap in there

Yeah I would say this is about 10x brighter than the stock bulb. Definitely wish I did this a while back...
