Diode Dynamics HP24 LED Bulbs

The Diode Dynamics HP24-Color LED Bulbs are designed for customers who want a modern switchback upgrade in compatible front turn signal locations. These dual-color LED bulbs display a 6000K cool white running light when the headlights or parking lights are on, then automatically switch to amber turn signal output when the turn signal is activated. Once signaling stops, the bulb switches back to white.

Built with high-power Samsung LEDs, the HP24 design uses 16 amber chips and 8 white chips to deliver a clean dual-color lighting effect. Diode Dynamics lists the HP24 at 410 lumens, providing about double the output of many factory bulbs while using measured lumen ratings rather than estimates.

The HP24-Color bulb is engineered for reliability with constant-current circuitry, transient suppression, and fully aluminum construction. These features help manage heat, reduce flickering, and support dependable performance in automotive lighting circuits.

Diode Dynamics lists HP24 switchback bulbs as non-polar and CK compatible on supported 3157 applications, helping simplify installation across more vehicle socket types. The bulb is designed as a direct replacement for compatible factory incandescent front turn signal bulbs and is intended for vehicles with clear front turn signal reflector lenses.

Because LED bulbs draw less power than factory incandescent bulbs, some turn signal applications may require a resistor, LED flasher, or hyperblink fix to prevent rapid flashing. Fitment should always be confirmed by bulb size, socket type, lens style, vehicle wiring, and intended function before ordering.

Whether customers are upgrading front turn signals, creating a cleaner cool white front lighting signature, or adding amber/white switchback styling, Diode Dynamics HP24-Color LED Bulbs deliver a premium socket-based LED upgrade. Now Available at LEER!
