[300Con23s]

I believe all HID kits are illegal in the states by DOT. The problem with the kits is that the beam and light will blind oncoming traffic. The actual HID's adjust and level the beam so the beam is flat and cut where as a aftermarket kit has no cut off and light goes everywhere. Unless it's the OEM xenon system that comes with the 300C, your pretty much going be wasting money on a illegal HID kit that will blind on coming traffic.
