Our Bullet Style SWITCHBACKS™ LED 1157 Inserts are industry leading LED turn signals that utilize today’s latest automobile lighting technology! Our Bullet Style SWITCHBACKS™ LED 1157 Inserts feature ultra-bright surface mount LED running lights that will shut off when the turn signal feature is activated. The turn signal will then flash bright Amber or bright Red to OFF until the signal self cancels and the running light comes back on. The Switchback feature creates a much more visible turn signal, front or rear and more visibility adds SAFETY!
