hi Sajit,
i bought the same hid projector for my thunderbird. the prob is the 5ah battery dies off very soon, leaving me in the dark. am not able to take the bike for long rides during night

It can also be a charging issue, which the mech is now trying to fix.
my question is if the rectifier and battery are good, do you think the proj HID can comfortably be getting power with a 5ah batt, or do i need an upgrade to 7 or 9 ah ?
