Been trying different bulbs on my Grom. Regular led and a Cree led. But the output isn't all that well. It's bright up close but not too good from far distances. I would like to run a single bulb hi/low kit with a relay. I have a feeling it's going to kill the battery though. And without kickstart I really don't want to chance it. Here's a pic of the current bulb. I will try to get some night pics.

There is a bunch of info on the web about the HID and light dispersal vs halogen bulbs. From what I've read you need a headlight assembly with a projector beam for the HIDs to be as efficient as they can be. The HID kits actually draw less current when they are running. They do have a higher initial start up as compared to halogens though. This is why they have ballasts. Inside the balast they have a start up capacitor. Once they start the xenon in the bulb is puts off photons when a high frequency power source is applied. I think around 20khz. I used to play around with building my own EL wire ballasts using transistors and 555 chips. Try getting a projector headlight assembly and get an HID kit with the digital ballasts because they are a lot smaller. There are all kind of bulbs to choose from.

Might want to do your research, our charging systems are a bit weak and may have a hard time getting an HID system to fire. Once you get over that hurdle you are still stuck with the fact that HID is not meant for a reflector housing. So now you have to find an appropriate housing to distribute the HID light properly. In a reflector housing you are getting very little light where you need it on top of blinding oncoming traffic. Easiest way is to get the Thai headlight and then work on the voltage issue.

Or be blinded by your retarded light output and then run you over. There is a build thread on here that you must have missed where a guy bought the Thai headlight and the HID retrofit and had an issue with flicker at idle. I know my stock charging system has trouble putting my stock headlight at 50-75% output at idle.

The stock US headlight flickers at idle, not a big deal, ruckus headlights flicker at idle as well and people run dual hid in those for years because they're done correctly (ie no flicker at idle)

I've had two people in just the past week coming home from work at night change lanes into me, when people get blinded they pay attention.. They don't close their eyes and swerve all over the road, avoid me is what they'll do, not hit me

He or anyone else will have a flicker issue if the power isn't taken directly through the battery via harness and relay. That is the only correct way to install hids. If one were to run it off the stock wiring it will definitely have problems. Hell the stock bulb flickers and changes in rpm range.

The low output and flickering is because the alternators are Y wound not Delta wound like on a car, most motorcycles are that way.

I installed hid on my custom projector headlight. The stock headlight socket doesnt have enough power to turn the hid ballast on so What I did was buy a hid relay kit for a h1 bulb and hook it up to the battery and ran it to a on/off switch. I tried running the feed wire to the stock headlight low and highbeam and it still didnt have enough power to turn them on. Pics are in my build thread.

Finally what I was looking for! Thanks for the info!

Gave it a shot today. Used a ddm hi/lo kit I had in my garage. I didn't have a hi/lo h4 bulb so I used a regular low beam. This is a full replacement harness HID kit that uses the stock h4 plug just to turn the headlights on and uses power from the battery to give the headlight a solid 35w. I need to get a video but it came out great plenty of room under the plastic to conceal the wiring.

^looks awesome! Is that an h4 bulb or does the projector use a different size. Because I have a projector showing up any day now.

Thanks 1bad. I am looking at some different lighting options right now. Having a hard time tracking down the housing I want for the light I am thinking about using. Definitely going to be something interesting.
