You should be powering them thru a relay anyway & just using the stock headlight wire to trigger the relay, and the cost of the timer relay over a standard (high quality) 'bosche'-style isn't much - the one I posted is only ~$26 shipped.

Oh - and while some bikes don't turn on the headlight until the bike is started, my GSXR750 switches on immediately & switches off when the starter is pressed. I'm assuming your Busa operates the same way. If not, and it doesn't switch the lights on 'til after starting, a timer relay would be redundant (though a regular relay should still be used).

I wired mine with a relay. Can I wire the timer right into the relay I've already run?

You could make it work, using the timer relay's output to power the other relay's trigger coil - but it would be relatively messy & give you twice the connections/components for potential failure. Also, the timer relay is solid state (transistor doing the switching), so I think its lifespan & reliability is probably much better than a mechanical relay. Since it just uses std. spade terminals, it should be easy to just replace your current one.
