Review: B R I G H T - I bought these for my old pontoon boat for replacements to the front navigation lights. The bulb I removed was over 20y old. So those lights were dim and finally burned out. I wasn't sure it would fit until it got here but the brightness is almost fascinating. I turn them on sometimes during the day just to show off how bright they are.
Review: Brightness - Love them very bright my dome and trunk are bright enough to view anything I need to get or do

Yes, this 42mm/3030/212-2 led works & All these Phinlion LED’s also work on a 2007 Dodge Ram 3500 MegaCab 4x4 Dually, models: 194, 2835, 212-2, 42mm, 3030, 3157 clear backup/reverse lights, H8/foglights, I couldn’t find a Phinlion name brand H13 led front headlight hi beam/low beam for this truck or else I would have bought that also. All Phinlion name brand LED’s I’ve bought for this 2007 Dodge Ram 3500 MegaCab 4x4 Dually have worked just OEM style PLUG & PLAY No B.S., no extra stuff, no attachments, no splices, no cuts, no added/extra Canbus, No Added/extra Resistors, you get the point, All these Phinlion name brand LED lights work on a 2007 Dodge Ram 3500 MegaCab 4x4 Dually. I’ve only installed them this month so I didn’t comment on longevity or else I’d be lying to ya, but I will comment later if something does go wrong. God Bless You All!
