Diode Dynamics 1157 LED Bulb HP24 Dual-Color LED Cool White Pair
$79.95
Upgrade. Add dual color functionality and a modern appearance to your front turn signals with the 1157 HP24. Populated with sixteen amber chips and eight white chips, this bulb lights up white when your headlights are turned on, and flashes amber when the turn signals are activated. Housed in an aluminum casing for maximum heatsinking properties, the HP24 will last for years to come. Best of all, installation only takes minutes - simply take out your factory bulb and the HP24 will fit snugly in the socket.

Switchback. Some vehicles use a dual filament front turn signal bulb, which allows you to add switchback functionality to your turn signal location. From the factory, the front turn signal lights up half power amber when the headlights are on, and flashes full power amber when the turn signal is activated.

By using this dual-filament design, along with the embedded digital timing circuit, you can upgrade this look: the HP24 lights up in a 6000K cool white color when your headlights are turned on, and flashes amber when the turn signal is activated. When you switch the turn signal off, it switches back to white. This allows you to upgrade your front end to an all cool white appearance, while still keeping your turn signal functionality. The HP24 bulb is only suitable for vehicles that have a clear front turn signal reflector lens.

Brightness. At 410 lumens, the HP24 will provide about double the total light output compared to your factory bulb. All Diode Dynamics LED lighting is rated with accurate, measured lumen figures, not calculations or guesses. We test the true output in-house, and provide you the real numbers to compare.

Reliability. Unlike other bulbs on the market, this bulb is built with constant-current circuitry, along with transient suppression. That means this bulb will last for years, not months, with no flickering or failure. And like every Diode Dynamics product, it's backed by an industry-leading three-year replacement warranty.

Experience. After over a decade in business, Diode Dynamics is the most trusted name in automotive LED lighting. Unlike every other LED distributor, we assemble and engineer products ourselves in the United States, for high quality and fast time-to-market of the newest and brightest LED technologies. We pride ourselves in offering only quality LED products, that will exceed your expectations.

Who is Diode Dynamics?

Diode Dynamics started back in 2006 by Paul McCain. It started as a hobby. And using some parts from Radioshack, he was able to create some LED accent lighting which he sold to some of his friends. 

From then on, the company kept on growing to offer more products and employ more people as they progressed. Today, the company is recognized as one of the most reputable LED light manufacturers in the market offering replacement LEDs, Full LED assemblies, multicolor accents and special unique modules.

From Importers to Manufacturers

During its early days, Diode Dynamics was just rebranding LED lights from overseas, but as they realize, they could create something better. So from then on, they manufacture their own products and have moved into a bigger facility with their design engineer. The company has its own light tunnel to measure beam patterns and various testbeds that ensures that their product is durable to handle whatever weather condition it is subjected to. 

Driven by their passion, Diode Dynamics has become the largest specialty application aftermarket lighting manufacturer in the US.

Stipulations
All schedules are based on the number of days between original purchase date and receipt of RMA information by Diode Dynamics. All warranties are non-transferable. Warranty terms and policies are subject to change without notice.

All warranties, expressed or implied, are void if our warranty claim department determines that there is sufficient evidence of one or more of the following:

For modifications to wiring, electrical components, or connectors, our staff will assist as possible, but is trained to support problems that arise in the course of standard use, without modification. Product instructions and installation guidance should be followed as written.

Replacing lenses on lightbars will void the 3-year limited replacement warranty. However, the 8-year limited warranty will be upheld and in effect. In the case of moisture intrusion, you may be required to open and re-seal the lamp yourself. If issues persist, we may require that the lightbar is returned for repair.
