Drag Specialties dual ring turn signal inserts are now available with 2-in. diameter GEN 300 Series LED clusters that are even brighter than the original design. Available in bullet or flat lens style styles, these inserts feature an outer ring of 24 white LEDs that function as driving lights and an inner ring of 24 amber LED turn signal lights.
When the turn signals are activated, the white LEDs turn completely off for the entire turn signal cycle, providing greater visibility to the amber turn signal. The inserts must be used with a clear or smoked lens (sold separately).
Sold in pairs. They fit signals with an 1157 bulb base and are BCM and DOT compliant.
