Simple time switch "Help" Answered

I live in a narrow road with high walls each side.   Getting my car out of the gateway is therefore a problem because I have to stick the bonnet out into the road before I can see that it is clear.  So I bought a 12 volt LED flashing beacon to put on the top of the wall at my gate.   Now I need a device which will run the beacon for about 20/30 seconds after I push a button, giving me time to get into my car and edge out.  I could, of course, stop and block the road while I go back and turn the beacon off but a time switch would be a help to good relations with other drivers.   Can anyone please tell me of a suitable switch or circuit?   John C

Why not mount mirrors on your bonnet instead?

Or one of those domed mirrors that are mounted on the opposite side of the road.

A big shiny-nose... I like that idea.
