Hi, I've found another document with a photo of the circuit board, the address is:
You would need to use the controllers lamp output to switch a relay, and then that would in turn switch a higher load if required. If you selected lights with integral dusk sensors then they would only light when it is actually dark.
Use a relay as described.

OK, well it seems that the controller board has a relay for the courtesy light output, which is good, because our "new" relay would most likely not provide enough load for a triac to work properly.
It seems that the relay is soldered in to the board, so hacking the board would not be a good idea (in re: creepage and clearance) if you are not very sure about what you're doing. I suspect that an additional relay (poss. on a timer to increase on-time) is the order of the day.
John, I think you would find that "lights with integral dusk sensors" would most likely need a permanent live feed to allow the electronics to settle down as these items have a hysteresis period of (probably in the order of) 30 mins. I don't think you can fire them up from cold and expect an instant "it's dark so switch lamp on/it's day so don't switch lamp on" response. As Owain has already indicated, it would likely be best to use a permanently powered dusk/dawn sensor and use a relay contact in the switched live output from the dusk/dawn sensor to only switch the courtesy light on when it is both dark and the gate operates.
The dusk sensor I have in the lights on the front of my house is an "instant on" variety. It's just in series with the switch.
The bad news is that I have no idea where it came from.
OK, didn't know you could get those.
I would suggest one of the DIN mounting contactors would probably be easiest - saves needing any bespoke wiring. A small enclosure could then be powered from an alternate source, and just take the control box output to drive the contactor.
Yup, agreed. The dusk dawn sensor and the light would effectively be powered from the alternate power source. Just the trigger would come from the gate controller.
