Your halo rings don't match your headlights' color?
Now PIAA's Exclusive LED Ring Bulbs will change that.
This bulb and socket assembly replaces the stock unit to give the vehicle's headlamp ring a clean, white 6500K brilliance. This upgrade changes the ring color from an incandescent yellow to a brilliant HID-like to more closely resemble the factory HID headlamps.
