HDHalo Technology: These universal-size halo rings feature all the benefits of our exclusive HDHalo technology, including:
- Proprietary durable phosphor coating, to create uniform, solid appearance.
- Extremely bright, high-density LEDs that are visible even in direct sunlight.
- Multi-function PWM drivers, fully waterproof, featuring low power, high power, and turn signal modes.
- Integrated mounting tabs for easy installation.
Sizing: All sizes are listed by outside diameter, in millimeters. Width is 8mm, so inside diameter is 16mm less than outside diameter. Total height is 4.5mm.
Wiring: All wires have a durable braided wire covering. The LED has a 20-inch wire with female JST type connector. This connector may be de-pinned in order to run wires through small holes during installation. Both the input and output wire on the driver are also 20 inches each. A pigtail is included that is also 20 inches, with male spade connectors on the end to connect to factory wiring with included T-taps. You will have plenty of room to run wires anywhere you'd like.
PWM Control: Aside from the high brightness and perfectly uniform output, one great feature of these halos is the integrated multifunction PWM dimming control. The drivers have four wires, to be connected to any 12V signals as follows:
White: Low Power, 50% brightness
Red: High Power, 100% brightness
Yellow: Signal, 200% brightness flashing (dims if powered more than two seconds)
All input wires activate the halo, at different brightness levels. All white-colored halos ship with "low" priority drivers. This means that if both "low" and "high" power inputs are powered, the LED will light up 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 at 200% brightness momentarily, intended for signalling (dims automatically if powered for more than two seconds).
This entire setup allows you to connect the halo directly as a multifunction lamp, without no external controllers needed. Of course, this is completely optional. You can just use one of the input wires if you'd like.
Installation: If you are installing these in headlights or tail lights, professional installation is strongly recommended, as the factory lamps must be opened for installation. The halos must be custom-mounted in position using adhesive or beading wire using the integrated mounting tabs. If you wish, mounting tabs may be removed with a pair of clippers or basic sanding.
