Temporarily unplug both HID ballast units, then install a stock bulb in just one headlight wiring harness plug. Flip the switch on. If it lights, your HID's are faulty.

It's not unusual for HID ballasts to blow. There are cheap units for sale out there.

Not saying you bought cheap, but before you blame the switch (you did say the parking lamps work...), I'd first rule out the HID's.

A simple test light (or better, a multimeter) will provide you with the answer. With the headlight switch in the headlight position, you will have 12 volts to energize the headlight relay. From the output of the relay, you will have 12 volts to the headlights.

Start at the heatlight wiring socket. With the headlight switch on, prode for 12 volts, working your way back to the relay, fuse, and headlight switch.

It's very rare for a headlight switch to fail; no high current flows through the switch. It's mearly a trigger switch for the headlight relay. This relay is what provides the 12 volts and current to the headlights themselves. I'd suspect it way before the dash switch.

Unless you were tampering with it....
