latching with a timed relay
I don't know if this helps, but if you are looking to turn on the lights for a few seconds to a few minutes, you could use the button to trigger a 555 timer circuit that drives the relay. This one will turn on the lights for about a second. Increase R4 or C2 to increase the delay; there's a chart in the data sheet that you can use to figure out the right values to use. R2 will depend on your relay.
