it's simple to change the bulbs out, just pull out knobs, remove screws, then remove 2 screws at top part of air vents, then pull cover towards you to remove, maybe 6 clips holding it in place. bulbs are cheap, they have a green cover on them that does not come off easy with out ripping. I changed my bulbs when they were out and didn't put the film back on, just a little brighter than is was prior.
