There are the DRL lights which are the turn signals, and are orange. Then there are the fog lights which are a halogen yellow.
If you put in HID (bulb type 9005) in the fog lights, then you will get a nice bright white/blue color. Now, you can certainly keep your old halogen bulbs from you old DRL and put them in the sts-v fog to make the turn signal not orange and at the same time lose the eggyolk effect (orange looking inside of the sts-v lamp). If you still want amber turn signals and DRL, you can get silver coated amber lit bulbs to put in there to remove eggyolk effect. You can also put in amber or white LEDs which will give you the same effect. (keep in mine, you will need 25w load resistors.)
You can also disable the DRL from being on during the day by reading the FAQ at www.cadillacfaq.com .
