If your car is wired up with 2 trailer sockets you could fit reversing lamps to your trailer like on modern caravans, I find it useful with my trailer.  If you do wire them on your car then I would suggest the ignition live source for your switch should be the reversing light circuit, then you don't risk them being on either when the car is parked or traveling forwards.  Halfords stock a decent fused relay that I use for all the auxiliary lights on our car.

Benji:
Thanks for your replies guys.

Think i need to have them on the car as its a long trailer and its quite tricky getting it along side the house and into the garden so if the lights are on the back of the trailer ill still have a dark area along side the trailer. I did consider wiring direct to the reversing lights but i don't think the cable will cope with that. Any thoughts???  (Haven't bought the lights yet but most of them seem to be about 55W)

I also considered using the 12S socket but i will still need to have a switch somewhere and i also want to use them to sort the dog and all my gear out after the shoots on dark evenings.

What is involved in a relay?  Is it just an in-line box wired up similar to a switch?  I couldn't really make out the wiring diagrams from Chris.

ChrisW:
The relay is basically a heavy duty remote switch. The idea is if you're taking two spotlights @ 110watts (55 each), this pulls just under 10amps - if you didn't use the relay you would need to have a heavy duty switch on the dash and all the wiring would need to be uprated.
The relay comes as a small black box with four spade terminals on the end, numbered up as my diagram - as you said, just an inline box wired up as a switch  :wink:

Range Rover Blues:
If wiring up spotlights is not your thing think about buying a ready made wiring loom for the spots, some Ring lamps come with one in the packaging or they cost about £12 to buy separately, a good relay costing half that on it's own.
Another quite useful option is a remote control accessory switch, designed for fitting spot lights to cars where you don't want to pull the dashboard out to 'hard wire' the switch.  Added bonus, you could operate the switch from anywhere near the car, like an alarm.  Again look in Halfords for this.

NOTE:  As previously stated you must have a warning light/buzzer on the dashboard if the lights are not switched by the gear selector ie they could be left on when driving.
