Yeah, what comes up on the Superbright site is a close fit in RRC Dome lights. I got the 3-LED versions, and the circuit board is slightly longer than the glass on the type bulb, resulting in very tight fit to the bulb holder tabs. In front I angled the bulb aim slightly rearward to clear the tabs. But for the rear dome, the board interference was too much when aiming straight down, so I had to decide on Right- or Left-biased. With a 120-degree spread it still covers the whole rear seat.
They are not my preferred color temp, but they sure do light up the interior, and they minimize battery drain if the dash button is left on (my main reason for purchasing them)! In the same vein, since all Classics spend some time with the hood up, I also replaced the under-hood trouble light with an LED!
