I think I've read that some of you have installed a timer to turn on your HIDs after a period of time to avoid the extra flicker caused by starting the bike.

I was thinking about this and being that the flicker is less than 1 second it might be easier to just install a capacitor on the input to the ballast? Cap will hold the rail long enough to cover the <1s drop in the supply. That's the thought anyway.

Does anyone see a problem with doing this?

I had a concern with the flickering of the HID when starting. I was afraid it would damage the ballast.

I installed a switch on the handle bar that shuts down the control power to the added relay. I shut the light off when I shut down the motor and turn the light on after starting. Simple and solves the problem.

Drive the HID's or HID's relay with the factory lighting wire. Then they will be off when the starter is cranking. If you use the O/W wire in the headlight connector it is hot while cranking and you will get flicker. If you use the blue wire going to the LH switch cluster to keep L beam on with highs it will fire on with the key but shut down while cranking. I put in a relay that keeps both headlights off if you have the H beam switch on when turning on the key, great for doing service. When you switch to L beam lights turn on and L & H work as always. Very easy to wire in. Diagram is in earlier post.

I think you would need a very large capacitor... more like a small battery.

The timer delay is about $4 worth of parts at radio shack, and car stereo shops (and ebay) probably have relays with the timer built in.

Or just a switch...

Drive the relay off of the accessory outlet wire. The outlet does not power up until after the bike is running.

I have my Motolights wired in this way.

Just the opposite on the Pre 08 bikes, it runs as long as the key is either on or in park, doesn't even get cut when you press the starter.
