Did the 1999 STS come with stock HID's??I am asking becuase I just baught this car and currently it does not have HID's and the lightsseem really dim at night. So I am wondering if it is supposed to have HID's or not. Thanks in advance for any info.

 

I think halogen. You can purchase some good replacements that are very bright, Sylvania comes in white light or blue light for your car. There are other brands too. Usually cost about $20 per bulb.
