Not trying to be frugal at all. Just thought I had read where people were having trouble putting the dust caps back on. Figured I would bypass that with the L shaped bulb. I would rather go with a morimoto set if it's not a problem getting the caps back on. You did the FXR upgrade didn't you? No problems with the dust caps and the bigger projector? Doesn't it use a DS2 or D2S (I think that's the right number) bulb? If so, is that a straight or L Shaped? Not sure why some are having trouble and others aren't. Drilling the hole for the grommet in a different spot or something? Didn't a user on here fab new extended dust caps for the Silverado because his factory wouldn't fit after the upgrade to HID?
