Overview

Upgrade your turn signals with the Diode Dynamics 1157 HP24 Switchback LED Bulbs, designed to deliver dual-color functionality and a sharp, modern appearance. Featuring 16 amber LEDs and 8 white LEDs, these bulbs shine 6000K cool white when headlights are on and automatically switch to amber when signaling. Once the turn signal is off, they switch back to white for a sleek “switchback” effect.

With 410 lumens of output, the HP24 provides nearly double the brightness of factory bulbs. Thanks to advanced constant-current circuitry and transient suppression, these LEDs are built for long-term reliability without flicker or premature failure.
