Introducing Diode Dynamics Switchback HDLED Halos! The first and only LED halos that are 100% Made in USA.

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.

Your order includes two halo rings, two drivers, two pigtails for easy wiring, and eight T-tap connectors.

Sizing:These are 80mm halos as 70mm will sit close to the projector which could result in overheating and physical interference.

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 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
Amber: Signal
Black: Ground

The white and red wires both activate the main color, at different brightness levels. For switchback rings, this is 6000K white. Your order will ship by default with “low priority” drivers, meaning that if both wires are powered, low power will take priority. 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. Of course, this is completely optional, and you can just use one of the input wires if you’d like.

The signal wire will output even higher power to the ring, so it cannot be run constantly, or the driver will overheat. It should only be connected to a turn signal. If you’d like amber for a running light, please select the single color amber rings.

For single colors, the same drivers are included, so you can operate the light with low power, high power, and as a turn signal that switches off and back on completely while blinking. If you are interested in solid red halos for tail light use, just email us to request “high priority” drivers after you place your order. With high priority drivers, you can use a red halo as running, brake, and turn signal, without any extra drivers or controllers needed!

ELECTRICAL SPECIFICATIONS:

Input Voltage:9-16V

Input Power:Dependent on size, generally one watt per 10mm diameter in “high power” mode

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.

WARRANTY

All Diode Dynamics products are backed by a 3-year replacement warranty.
