They used to be illegal because laws required "sealed beam" but mfrs change that when they went to OEM equipment with capsules type bulbs.
Sealed beams were used for years but if you ever noticed, cars w/sealed beams always seem to be driving "one eyed" whenever there was a temp change. Reason was seal between glass & backing contract at different rates. Once air got in -"adios" Capsules last longer and aren't affected as bad by temp changes
