Can anyone suggest a better way or ready made supplier for this?

I'd like to light up my new house's drive when the car arrives/leaves.
(It's easy to damage the tyres on the stone edging on the drive ).
But since it's a long drive & to save time/expense I don't want to mess
about with buried mains cable.

It seems all I need is a PIR that supplies a switched mains feed to one of
these low voltage drive lights sets you can buy that just plug into a 13A
socket.. Then just run low voltage cables to the lights (about 4 of them)

But I'm not so sure about getting the switched output - I can wire up a PIR
from the lighting circuit, but then I presumably have to put the switched
output into a fused 13A socket for the lights transformer?

Something tells me there's a better way.....? Can you get low voltage
PIRs - I thought of alarm systems but I 'd need it to stay on for a few
minutes?

My other alternative would be to use one of those radio controlled mains
sockets and keep a transmiter in the car, but then I have to remember to
switch it off when leaving, unless you can get one with a timer .

Can anyone help with suggestions - thanks
Keith

Drive is flat, approx 3 cars by 2 cars size , and has stone edging that has
sharp edges, arranged in a curve that's hard to judge at night.
