I thought the HID lights had a blue tint, mine do not.. I assume they are halogen? I have the blinking/going out light issue... If toyota thinks I am going to give them $500 for changing a light bulb.... nope
stock HID has a blueish tint but its more white than anything. and yes if you have stock fogs, you have HIDs
If you continue to have problems with your HIDs (if you have them) and Toyota won't help you out then I would suggest changing out the stock ballast and bulbs and going with a quality aftermarket kit. They can be purchased for $35-$150 and are fairly easy to install.
