Does Not Fit Polaris Ranger
Not compatible for Polaris Ranger as it was advertised. Not the correct thread so it will strip. Do not buy if you need it for a Polaris UTV.

No polarity and super bright.
Size: 194/T10, Color: White
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.
