Review: Brighter - Good quality light and luminous is also good.
Review: The stock dome says 28mm and the map lights say 27mm but these fit just fine. It's snug so either pre bend the metal fixture a smidge or just go gently pushing these in. The newer version of this bulb has a flat chip instead of the bubble chip. Same bulb though. They are actually a bit brighter with the flat chip. I have these in the map lights on 2 - 2023 Crosstreks and wish I had just gotten 2 more for the dome lights. I have Alla Lighting 31mm with the 12-3030 chips for the dome lights, assumed those would be brighter but they aren't. They are plenty bright though. Whole inside of car lights up, floor and all with all 3 on. As always, thanks Alla Lighting.

Was kind of a pain to install had to use a pair of needle nose pliers. big hands... The 2014 Toyota prius dome light is almost useless. But this thing, once in. wow what a difference. Way brighter. Now it lights up the whole inside easily at night. Hope this helps.
