Exactly! Those cheap little blue bulbs you see in auto stores are not HID's. They may contain Xenon in the bulb chamber, but they are still filament based. Not even close to the real thing. This borderlines on deceptive advertising in my opinion.
Did you ever notice how the same wattage "blue bulb" appears brighter than a similar halogen? That's simply because the human eye has a hard time filtering blue light so it causes more glare thus appearing brighter. They actually reduce your ability to see at night... real helpful!
