Obviously, you need the headlight assembly... the piece the cheaper bulbs actually insert into or it certainly wouldn't cost so much!My OEM source of parts is cheaper than your dealer's quote but still higher than I would like to pay for... check it out:http://www.acuraoemparts.com/delray/...l&vinsrch=noOf course new parts are going to be expensive, especially if bought from an OEM source. Your only other resource is to enlist the services of one or more used part sources. These days, all the wrecking yards subscribe to a parts locator service. This online service lets you type in all the details of the parts you need and then forwards the request to all member wrecking yards. The ones carrying your part put together a quote and email it back to you. Pretty convenient really. I've bought some parts this way and was happy to find it works rather well.Try starting here:http://www.haprecycling.com/Good luck!
