If you get the right type of bulbs in the reverse lights they can be as bright as stock, just gotta make sure you have enough high power led's and facing the right direction (or reverse lights shoot light out the side, real weird design.

My led reverse lights were 40 bucks for the pair but are bright as anything, and I have no issues seeing even with 15% tinted windows.

There's a thread about led reverse lights I ought to post some pics in and give it a bump.

The interior is a no brainer though. Get about 20 led bulbs and go to town, no errors on any and really updates the inside
