The d2s is an hid lighting. It is an arc source type of lighting available as an upgrade feature in new vehicles from dealers. The white output, and the reflector design system, tend to give it a bluish/purple look. When replacing the xenon bulb, both must be done at the same time. The xenon bulbs change color with usage & time, hence the reason why one bulb will appear yellow & the other 'blue'.
The two piece, washer style, wheel bolt design allows for precise and even load distribution to the hub surface. This design reduces wheel damage caused by fixed taper wheel bolts that can gall the seating surface. The floating ball seat washer insures a more exact and even torque setting and load. Will fit all OEM standard wheels. Wheel bolt heads are hot forged for higher strength -vs - machined head. Rolled threads for greater fatigue resistance and avoiding galling -vs- cut threads. Wheel bolt kit incluses 20 wheel bolts, 2 wheel hanger studs, and t80 torx socket.
