2003 CTS 3.2 Litre Motor - What kind of Headlights do I have???
 

The lense was busted and I'm contemplating replacing the passengerside lense however my search has led me to three different models... One being Xenon, One being HID, and Standard... How do I know which lights I have?

Ask the Dealer.

I read a bit more - According to the "Customer Convenience / Personilzation Guide" that was n my 2003 CTS:

"Vehicles equipped with the optional high-[intensity]-discharge headlights will be equipped with headlight washers."

I bracketed "intensity" because in the Guide it is printed "high-density-discharge" which we know is not correct... so, if you have headlamp washers (headlamps must be on for the headlamp washers to work), you have HID headlamps.
