Recently traded an '08 KLR for a new '09 Versys.
When I prepped the KLR for trade, I removed the HID low beam that I had installed a year ago. The reason for this is I looked online and saw that the KLR and Versys used the same bulbs so I knew that I could save a few bucks and use my old HID bulb on the Versys.
The re-install on the Versys went pretty smoothly since I'd done it before. The only snag was finding a good place to mount the cigarette pack sized ballast box under the dash somewhere.
On the KLR, there was a flat spot that I mounted the box to with the supplied double sided tape. No such place existed on the Versys.
In the end, I took advantage of the fact that the ballast box had two tabs on one end and one on the other that could be used to fasten the box down with screws. Instead of screws, I used zip ties.
I put the end with two loops at the top since the loop(s) at the top would hold the weight of the box and zip tied the box between two small parallel frame members behind the headlight. This brought the cords out the bottom, which was fine. The cords were then looped over the top, across behind the light and then back down to plug into the bike wiring harness and installed HID bulb.
Here's a view of the ballast box (which still has residue from the two sided tape used on the KLR) taken from under the right handlebar:
Here's a view from the right side:
And a view from the left side:
You'll notice in the above picture (which is completely installed) that the stock plug is not hooked to the back of the HID bulb. Instead, a single red and black wire exit the rubber boot and make their way to the ballast. The original plug is still used by plugging a pair of spade connectors into the plug for 12V and ground.
FWIW, I bought my HID lights from http://www.carhidkits.com
. I bought the smaller "Slim Ballasts" and was glad that I did.
The kit I bought comes with two ballasts, two HID bulbs, two wiring harnesses, etc. Since I wanted to keep my high beam stock (for instant on), I have a spare to install down the road when needed.
The light from the HID lights is very white and bright and I definitely prefer it to stock since I live out of town and commute in before sunrise every morning. I am happy with this HID package.
