Holley RetroBright led headlights

The Holley RetroBrights are a promising new product. I was asked for some input during their development, and I expect to have samples in hand soon to scrutinise and evaluate. First impressions based on test data: very good low beam performance. High beam performance is more of an open question; probably not lousy, but maybe not excellent.

And yes, they plug right in (without adapters) and physically fit every A-body from '63-'76, and all other vehicles that take a 7" round headlamp, with the only exceptions being some vehicles that have headlight mount cups not built quite to the specification—sometimes the centre hole is smaller than it's supposed to be, or it's only a "half hole" (shaped like a lazy-D). This never made a problem with sealed beams, where the hole only had to be big enough for the three electric terminals. With other-than-sealed-beam headlamps (H4s and maybe these RetroBrights) the small/half hole might have to be enlarged. Removing and discarding seal boots is not the right way to do it; they're there for a reason, even on the crappiest pretend-headlights.

And since we're on the topic: Rampage = fraudulent headlite-shaped trinkets, not capable of producing even minimally adequate safety performance, let alone working great or being much better than the old school ones. The reason why it seems otherwise is that what we feel like we're seeing isn't what we're actually seeing. The human visual system is a lousy judge of how well it's doing. "I know what I can see!" seems reasonable, but it doesn't square up with reality because we humans are just not well equipped to accurately evaluate how well or poorly we can see (or how well a headlamp works). It's not because we're lying to ourselves or fooling ourselves or anything like that, it's because our visual systems just don't work the way it feels like they work.
