Same here...except brake light bulbs, turn signals and I think that's it. Replacing OE back up lights with LED's made a big improvement along with all the interior lights that I replaced. Like you said, inexpensive and quite easy for a DIY.I replaced all my bulbs with LED bulbs except the turn signals, way too bright. Kits on Amazon are not expensive and they really improve lighting in the car especially the backup lights.
