True HID better than Xenon filled lights?
I'm wondering if anyone knows if there is truly a difference between True HID bulbs or the regular Xenon filled kind. The price difference is like 100 dollars so i would really like to know before hand. I know the Xenon kind advertises that the K color (like 8000K or 10000K) are the same but i thought the silvania cool blue bulb would be like that and it ended up being no different than the stock headlight. I've learned to not trust advertising so i need the input.
