hi-low beam relay

Hi!I would like to use a relay to change between the high and low beam on my motorcycle. The button to control this is a push button. Actually a microswitch kind of type. So every time I send a pulse to the relay, it should switch between low and high. And if nothing is sent to the relay, it should just keep the power as is.I have only found a relay that keeps the low beam on when I keep the button switch, but as soon as I let go with the button it jumps back to the high beam again.I also must mention that there is very limited space available to mount the relay. There is room for a normal bosch relay, but not two.

Maybe have room for a Saab 900 (85-90 yr) headlight relay? They are nearly twice the size of a standard Bosch relay, but it's all in one can, and they're easy to hook up. Or maybe a relay from a 9000- these are the same size as a single Bosch, but you'll have to check that out a little more carefully.
