how to tell if I have hid headlights
Posts: 15,450. Turn on the headlights and if the bulb starts out one color and then shifts to a whiter color, then she probably has OEM HID. Or open up the cap and pull out the bulb. You can tell if its HID or not because the two bulbs are completely different.r you could look on the actual headlight housing for the bulb code. if it's halogen, you'll see imprinted in tiny tiny letters somewhere on an edge of the clear plastic housing the letters HB2 for halogen or D2S for HID. oh yeah, if she has halogen and wants a better bulb, don't get the silverstars. they're junk.
