From the factory, turn signal bulbs are powered by standard incandescent lights that light up amber in color. Newer luxury vehicles are using LEDs for turn signals, because LEDs offer a crisp, instant on/off, increased brightness, and true, vibrant color. By replacing the bulbs in your vehicle, you can achieve this modern look! You can even add functionality to your vehicle with switchback bulbs! These light up bright white for running lights instead of dim amber, but still blink amber when you activate the turn signals, for a unique dual-color effect! The installation is 100% plug-and-play, just replace your factory bulb. The bulb may blink faster since it uses less power, and your vehicle thinks the bulb is out. HP24: 16 amber and 8 white, high-power LED chips. Full aluminum body for durability and advanced digital latching circuit for color control. 6000k, Cool White to match your HIDs or other LED applications.
