I have a 1982 crash manual with all of the GM part #'s. It doesn't list any plastic sealed beams. The numbers all cross to standard glass sealed beams. 5966200, 5966201 are the standard lamps. it lists 5930567 and a later book lists 16502327 but they are for halogen. The complete capsule assy which is the sealed beam with the bucket and ring are listed as 16503498-7 and 16501471-0 but I believe these are all glass sealed beams also. I have a 1992 crash manual and it shows the same. I don't have any factory GM parts manuals for those years.

If I remember correctly, the plastic sealed beams were a aftermarket thing. Don't remember who made them wagner maybe. Been a while since I worked at a parts counter.

I did find part # for plastic but I believe they are smaller than the standard sealed beam. I believe they are for Gran Prix and Cutlass FWD coupes. 16510872 16510873. Grote does make 4x6" LED sealed beam replacements.

I need to clarify my plastic sealed beam question. This is for my 1982 Camaro Lamplighter project
During the late 80's - early 90's GM & Ford built cars with plastic sealed beams. They are the small, rectangular bulb, installed in some Buick and Olds G bodies and some Ford Crown Vics.
The only advantages is, they are about 1/2 the weight of a glass beam. However, for the set of four, the weight savings would be three pounds. That was my only reason for seeking a set.
Lately, I have discovered they are no longer available new but can be found on eBay and other places as new/old stock. The average price is $35.00 each including shipping.
So, I will find other places to save three pounds for much less than $140.00
I managed to find a set of plastic headlights for my car. Although they remove a couple of pounds, the brightness just isn't the same as some glass/halogen sealed beams. Modern LED conversion bulbs are a much better choice.
