Features Fits many 4”?x?6” lamp applications. Actual halo size: 5.3” x 3.5” Proprietary durable phosphor coating, for uniform solid appearance Extremely bright, high-density LEDs that are visible even in direct sunlight Installation does require opening factory headlamps Engineered and assembled in USA Overview HDHalo Technology. The switchback rounded rectangle LED halos have been designed from the ground-up to be absolutely the brightest, most reliable halos physically possible. Each halo is populated with a large number of high-density (HD) LEDs, which are then coated by a diffusing gel, resulting in a perfectly uniform light when turned on. When off, the diffusing gel hides the chips, resulting in a clean, OEM appearance. 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.
