Complete 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.

Performance Some 921 bulbs are used in turn signal applications, the Extreme offers the maximum output possible within this package size. Adding load to prevent hyperflash is simple and easy, with no splicing or tapping into your factory wiring as standard plug-in style bulbs require.

High/Low Most factory 921 bulbs are single output turn or brake applications but we made the V6 Extreme 921 with a dual output driver. Guess you could say we have other plans for this bulb! Make no mistake, the V6 Extreme 921 is the clear choice when upgrading your factory lighting.
