• Direct replacement for factory 1157-size front turn signal bulb
• Dual-color: cool white running light, amber turn signal
• 16 amber chips and 8 white chips arranged around the bulb
• 410 measured lumens — roughly double factory output
• Requires a clear front turn signal reflector lens

Two Colors From One Bulb

The HP24 adds genuine dual-color functionality to your front turn signals, lighting up cool white when your headlights are on and flashing amber the moment the turn signal activates. Populated with sixteen amber chips and eight white chips arranged around the bulb, this housing is built entirely from aluminum for maximum heatsinking, and there's no yellow appearance when the bulb is switched off, unlike a standard amber bulb behind a clear lens. This bulb is only suitable for vehicles with a clear front turn signal reflector lens, so double check your housing type before ordering. It's the kind of upgrade that quietly does its job without ever needing a second thought.

Real Output Numbers, Built to Last

At 410 measured lumens, the HP24 delivers roughly double the total light output compared to your factory bulb, and Diode Dynamics rates every bulb with genuine tested figures rather than calculated estimates. Built with constant-current circuitry and transient suppression, this bulb lasts for years rather than months, with no flickering or premature failure. It's backed by Diode Dynamics' industry-leading three-year replacement warranty. That's real, functional engineering, not just a marketing claim.
