CREATION: For years the V6 Triton and V6 Extreme have revolutionized the LED lighting industry. Now we can say that the family is complete with a 921/T15 offering.

MAXIMUM: 921 bulbs are often used in reverse light or turn signal applications so the Extreme is the maximum output possible within this package size. Even though the bulb is maxed out, this product is still backed by our normal 3 year warranty so you can be assured that extensive testing has been performed to make sure it's safe.

END FIRE: Many modern reverse light applications have tiny housings so we designed this lens to increase the amount of usable light behind the vehicle. The lens almost acts like a projector shooting the light backwards to improve overall visibility when backing up.

WARNING: For reverse lights only. Installing this product in a constant on application like daytime running lights or parking lights will void your warranty.

FITMENT: This LED bulb replaces any 579, 901, 904, 906, 908, 909, 912, 914, 915, 916, 917, 918, 920, 921, 922, 923, 926, 927, 928, or 939 bulb size.
