Thanx so much for sharing. All cars have a story, the more years that go the more the story grows. Not all good sometimes. I will spare you mine for now I've owned my Type S since 2006 It's an 03. I first saw one at the Chicago Motor Show, looked at my then wife and we agreed we must have one! At the time we had a 92 integra. I could go on and on, on both fronts. In the interest of your RSX the show here must go on. BrutalB83 is correct. A buck fifty is out an outrage!
The drivers side, remove the battery, there is a clip that you slightly lift and move to the side. I believe it's to the right as I recall. The bulb keys in, I believe it's counter clockwise to remove? (been awhile) You should slightly push in as there's a rubber o-ring seal. Lube the new seals slightly with dialectric grease/ small service pack of break lube will work also. You can practice on your existing in hand housing??? I urge you to attempt this. YOU CAN DO IT. The passenger side a little more cramped. You can litteraly lift the P/S reserver out of the way if need be. The lights bolt in to a bracket ten millimeter comes to mind with an extension.
You can get repair kits for the light lens for 20 bucks +/- to make a go of it. It can be done on the car even. I can't imagine this gentlemen has anything better? There may be other "wives tail" ways you can goggle. Vinegar comes to mind?? Try not to touch the element of the bulb, where Dr's gloves if feasable. I always grab a hand full as a parting gift. Sometimes I take my mechanical ability for granted. I just think you can do it. If not o.k. I have a good vocab but my spellings for s**t? Keep us posted as this also helps others to know if anyone of us said anything that did the trick for you! Peace and enjoy the weekend. Cold as a witches tit here. Hope this lengthy responce hit a nerve somewhere?
