Posted this on another forum but thought I'd share it here as well.
Not much of a write-up really and I know this look doesn't appeal to some of the "purists" but I thought I would share my experience.
I ordered two sets of the 5" Felser Halogen headlights to replace the sealed halogens currently on the Chevelle. I wasn't wanting a blue bulb or the ridiculous HID crap but thought the newer style headlight housing would look good on the car and it is something I don't really see too much of, or not around here anyway. I try to keep my car a mixture of new and old by doing things that look similar to original but in a more modern sense.
Anyway, the install took maybe 10-15 minutes for all four headlights and a good portion of that was wiping down the areas hidden by the headlight trim.
Both boxes ready to go

Installed - Not nearly as noticeable when you are not as close but I really like how much "cleaner" they look. The appearance (IMO) is not really all the different than the factory sealed T3 bulbs the car came with. It just has a modern twist.
