I was looking at all the possibilities to upgrade my Grom stock head light to HID unit and I found this unit that is reasonably price to help out with the HID unit turning on 10 seconds after you start your Grom. I wanted more juice going to starting my Grom and having my HID light unit kick in after a 10 second delay. I think this would be a cheaper upgrade than some other unit that are being sold. Not bad soluation for $15+

HID Time Delay Relay - Retro-Solutions Store

I haven't had any issue starting my Grom despite having HID's installed without any sort of delay unit.

i installed one when i did my retro. while useful, depending on your routine prior to starting, 10sec can be short. in my opinion, a voltage sensing relay may be better. with this type of relay, the relay won't trigger until a certain voltage is reached. once reached, it will remain active until the ignition is turned off.

Where are y'all buying the kits from and which kit is the best bang for the buck?? I just bought a new headlight with projector and want to do the hid kit now. Thanks in advance

If you are running HID's you are going to have to do the ac/dc conversion to allow them to function.
With our product you get the ac/dc conversion and the delay relay in one unit. Connect it and your ready to go. Cut buying wires, no cutting wires.

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.

Probably going to do a projector retro with the OEM headlight I have before putting on our new lighting. Here is what we have done in the past. Something we can offer up as a service or provide backplates if there is a demand for it.

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 Left hand drive or Right 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.

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

I haven't had any issue starting my Grom despite having HID's installed without any sort of delay unit.

so did you connect your HOT wire to the rear tail light HOT wire or did you connect direct to the ING switch like some grom owners are doing. Not sure why you need a AC/DC convertor if you are connecting to the HOT tail light wire or ING switch since it goes to +12vdc and not the un-rectified ac voltage of the stock head light circuit.

 

[pwr2wh8]

the ac/dc rectifier is only need if you plan to use the original headlight power source, direct off the stator. i was going to go this route to simplify the install, but was worried how the ballast would uphold on the long run due to the constant fluctuation in voltage.

as with many, i went the route to convert the voltage at the headlight swtich to dc voltage by taping the rear tail light. this in turn triggers my time delayed relay to power the ballast.

thanks for the info, but was wondering would have it been better to tap off at the ING switch that way power is off on both the HID unit and the delay switch.

I'll figure out the shortest wire route to use with out making my Grom wire harness look like one of our IWC network closet with wires all over the place.

 

[LateNA]

I tapped the tail light. Is it the best option? No idea, just the option I used. Electrical is not a strong point for me.

yep I was wondering about the load esp if you are going to hook up a PCV, O2 sensor, LCD display unit plus the HID lighting system. I think a safe bet is to tap of the HOT from the ING and put a extra fuse holder or two for the HID and PCV unit. Might have to upgrade to a Lithium battery system such as Shorai, antigravity and other companies make.

Well shit.... ill have to look into doing the retro then. Thank you late

You can connect to the ignition however I do not think you will be able to maintain the high beam function. This is why we removed the headlight connection at the source to change it. Haven't tried it your way but let us know how it works out.

 

[pwr2wh8]

in theory, you can route any switched 12v source to your headlight hand controls and achieve the same result. however, i prefer to leave key circuits untouched to reduce any shorts/faults down the road that would affect that circuit.

for my install, i use the tail light as i preferred to have the time relay located by the battery. also, routing switched 12v from the tail light only need a 7" wire extension.

 

[Gremlin]

So is everyone doing the positive feed w/fuse from harness straight to +battery? and black grounded?

if one wants to add a switch to turn on/off HID. where would you wire it too and how?!

electrical is not my strong suite.

 

[tripage]

If you install our converter/delay you will have DC power at the OEM headlight socket and you can connect any light there. Just plug it in and your ready to go. No need for extra switch/wires/relays. This is one complete unit that will fix everything. It will delay your light from coming on till after the timer runs out and your bulb/hids will be on DC current instead of AC.
