You bought the Thai headlight? That isn't an HID projector and will not help you with an HID kit. You can go to TheRetrofitSource for you HID needs, but make sure you buy an actual HID projector.
I second that on the RetrofitSource.
I was having problems with how was going to fit my duel bulb HID system into their mini 6 morimo projector bulb and I called the company up and spoke to one of their sales/tech rep and he told me that since I have a H4 bulb that I use their H4 plate that is part of the kit and that I only need a single HID bulb that will act as the Lo/Hi beam. He said that in the projector kit there is a shade plate/wing unit that is activated by a relay unit. This relay is wired to your hi-beam wire and what happens is when you click your motorcycle switch to Hi beam the relay kicks in and drops/opens the shade plate causing more of the HID light beam to show through the bulb creating more lighted area.
My kit came with two projector blub unit, so this looks like it was for a car but it fits in the Grom bulb housing perfect, plus since I am going to have two Groms the second projector will go into the second Grom. When you order your kit it will have a selection for L
eft hand drive or R
ight hand drive and I guess the beam pattern
is different for projectors for USA or for countries that are right hand drive.
for my kit I have to take my duel bulb H4 unit and remove my yellow bulb and use the wire that went to this bulb and connect it to the relay.
There is also a shroud housing that goes over the projector frame, I guess that is from blocking the HID light from going all over the place and concentrating the beam into a forward pattern.
On your stock Grom light housing it looks like you have to use a hair dryer and heat up the outer shell unit that holds the clear glass/plastic to the light housing and using some plastic tool or some type of tool you pry the unit a part. There is 4 tabs on the Grom unit that holds the clear glass/plastic. The heat gun/hair dryer is used to soften the glue/silicon/tape unit that holds the clear glass/plastic unit to the housing.
here is the link of the kit I bought
I think I should have bought this kit since the mounting shaft fits the Grom housing better, since the mounting shaft is 35mm and the dia of the grom housing H4 bulb housing is 38mm.
This is what my kit looks like
notice the little plate unit, that unit opens up the small plate when you switch to Hi-beam causing more HID light to go through the projector.
Grom housing unit
you might be able to see one of tab that I was talking about that you need to unlock to get the clear off to mount your projector unit into the housing
