Nuh-uh, no he hasn't! Not until I see test data on these, which I don't imagine will be forthcoming from the Spaghetti folks. They may look keen and they may give every appearance to the casual observer of providing adequate safety performance, but that would only be a guess without data. The data needed include intensity throughout the regulated vertical and horizontal angles for both the dim tail and the bright brake mode, ratio of intensity between the dim and bright modes, and intensity maintenance with prolonged operation (even some of the name-brand truck/bus LED items have a hard time with this one). It's not all that expensive to have a full suite of safety performance tests done on an item such as this—about $500, tops, and probably less. But I will still be surprised if ever we see that data.
(And no, I don't mean they ought to be tested to the standards in force for today's cars, just the standards that were in force when the cars they're intended for were new. Not much difference between today's standards and the '68 standards, and as long as one were designing a unit like this from scratch one might as well design it to conform to today's somewhat higher performance requirements, but without data I am skeptical about the ability of these lamps to meet even the slightly lower '68 standards)
