I tend to open my trunk more at night (for someone else needing to go in it) or with the engine off, so it works for me. And, it was kinda just my OCD that it had the see-through white plastic, but no light lol.
I actually planned on doing the Cruise Control buttons too - way more practical and useful. Of course things happen and finances get messed up, so I had to put that aside =/ It def won't be easy, but I would think it's do-able, in a similar fashion to the trunk button. The main issue is that because the letters are just painted on, you'd have to basically cut each one out - very tedious; then fill or cover with glue or whatnot. I will do it eventually and make a How-To just in case.
For the record - I'm not a dude! Sedan Revolution # 99 -- Waiting on a location/funds 2 start my Custom Tail Light Project.
