No polarity and super bright.

Quick installation. Turned my halogen lights into led lights. No issues with polarity and no error codes. The license plate light shine much more bright than halogen lights. Amazing upgrade. Great price and highly recommend.

Affordable and hassle-free
Size: 921/912, Color: White
These reverse lights are super bright! The old bulbs left things practically pitch-black for night driving, total game-changer once these went in. Affordable, hassle-free upgrade that makes all the difference.
