These lights are New Old Stock. Similar to guide but a little larger . Use standard 7" lamps. Had some shelf wear that I corrected and put the shells in primer. The retaining rings are perfect as are the original screws and cloth braided wire harness . The chrome rings have very minor blemishes but are great for a nice driver and can be replated for a show car. I believe the rings are brass so plating is very easy. They look perfect on a hot rod. $100 plus the ride is a steal for an original traditional light. Bert 4402312318 or 4409748887
