So far so good with the Retrobrights, however I haven't had the car out on roadways at night beyond the neighborhood in recent months but I notice a definite difference. I also just saw that holley is doing some blow-out sale of the version1 of these 4x6 headlights and the only difference is something with the wiring or connector. I didn't get much details, but these are the version2 and they are still for sale in the $180 range. The ones holley had up for their big sale work equally well, and they are selling for like $75 each.
