I want to put some LED lights on my sliding gate. I wondered if I could

they are close together and the LEDs come on. The power requirement of
the lights is 24W at 12VDC. The positional accuracy of the gate is good.

That would be quite difficult, I think, by the time everything is
weatherproofed. Mechanical coupling might be easier - motor on the
gatepost operated by microswitch coupling to a generator on the gate.

Or a hose and a water wheel.

Instead of LEDs use phosphors which are illuminated by ultra-violet
lasers. The lasers are fixed and only illuminate the phosphors when
they're in gate-closed position. Can't see the problem.
