Halo Lights LED 90mm/120mm Blue Four Diode Dynamics Scion They are NOT cross-compatibleHDHalo Technology. These HD LED halo rings 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. Sizing: All sizes are listed by outside diameter,
