Truly Tailored Halos: These high-quality LED Halos from Diode Dynamics are available in any size under the sun and feature a special diffusing gel inside the halo to ensure a perfectly uniform LED Lighting experience. When off, the gel perfectly hides the internal chips creating a factory finish without hot or cold spots. If you're looking to truly customize your lighting, these LED Halos are a cut above the rest.

Sizing: All sizes are listed by outside diameter, in millimeters. If the width is 8mm, the inside diameter is 16mm less than the outside diameter. Total height is 4.5mm.

Mounting & Installation: It doesn't get much better than these when it comes to fitment and customization. You can use the integrated mounting tabs to glue these in place or hold them with mounting wire. In addition, in special fitment cases, you can even trim up to 20% of the Halo and maintain complete functionality.

Wiring: Complete with female JST connectors, each LED has a 20-inch wire for the input and output. Each pigtail is a further 20 inches to ensure you have maximum flexibility. To finish things off, the JST connector can be de-pinned to run wires through small holes during the installation process if need be.

Pulse Width Modulation Built In: The drivers have four wires, to be connected to any 12V signals as follows: White: White Low Power, 50% brightness Red: White High Power, 100% brightness Yellow: Amber Signal, double brightness, flashing (dims if powered more than two seconds) Black: Ground All input wires activate the halos, at different brightness levels. All switchback halos ship with "low" priority drivers. This means that if both "low" and "high" power inputs are powered, the LED will light up in white, with low power level. This is convenient for connecting the red wire to a parking light or DRL signal, for use during the day as a high-power DRL. Then, if the white wire is connected to the headlamp power, they will dim down at night. If the yellow wire is powered at any time, the halo will light up in amber color, intended for signaling. If you'd like to use amber all the time, no problem! It will dim automatically if powered for more than two seconds, to keep it safe. This entire setup allows you to connect the halo directly as a multifunction lamp, without any external controllers needed. Of course, this is completely optional. You can just use one or two of the input wires if you'd like.
