Installed HID in my bike ... costed me 3k wid fitting n all ....
Great visibilty as compared to OEM lights which runs on magnetic electricity...
HID kit for 3600 (pair)
Installed one unit on my bike and another one on broders so,what i paid was like
Dry Battery(12v,9AM) 650
Cutout Circuit 100
Labour + Wirrings 250
Modified Charger 150
Drink n chips 50 (while the installation is in process =p )
But it works gud in cars only.......as u got to drive ur bike too much in day time in order to charge up ur battery.......oderwise ull end up screwing up ur ballast wid low power from battery !
