I love the fact that they strobe when you first go in reverse to warn anyone in parking lots. Secondly there like having headlights backing up extremely bright would buy again and recommend.

921LED Replacement Bulbs

Perfect fitment and bright. The strobe flash when first initiating the light gets attention of anyone close and hopefully will help prevent any accidents.
