how do I tell if my car has xenon lights? Its a 2003. Do they have a specific look?

I thought it hadn't from the age but when I turn the lights on they seem blue compared to any other car I've had and they didn't have xenon.

 

all the S2000 lights are the same in every way except of the physical appearance of the housing (IIRC). They all have a HID projector beam low beams (not sure if xenon). If your lights look a different color than other S2k's there are a few explanations:

1) your bulbs are either newer or older (color shifts with age of the bulbs)

2) You have aftermarket bulbs with a different color temp than stock.

 

I believe we do.

 

The stock xenon bulbs are pure white when you look at the road in front of you. If the light on the road has a blue or cobalt color you have aftermarket bulbs. Blue light is less light.

 

Your bulbs might be the original ones that came with car, in which case they have colorshifted over time. HID bulbs lose output and shift in color towards the blue part of the color spectrum as they age. Brand new Philips 85122+ HID bulbs start out around 4300K and will have a crisp white output and will offer you the best visibility at night.
