I didn't do a true HID, but i did put in a new H4 6000 bulb in for like 10 bucks and it made a huge difference. I believe the high beam is a 95w.
Did you use something like this:
H4 130/90W 6000K Xenon HID Light Bulbs (1 PAIR)
Platin Xenon light bulbs use quality silex tube and fill with refrigerated xenon gas, which is refrigerated by liquid nitrogen, the tube will not burst because of bleb or hydrosphere. The bulbs will be much more effective, that the luminous efficiency can be up to 28 cm/w. The average life is 30% longer than ordinary halogen bulb.
*Xenon Gas Filled.
*Super White, 12V, 6000K, 130/90W, H4
*Simply remove stock bulbs and replace.
I've been considering it myself.
