One turns the LEDs on when you approach using the power to accessory lights as a trigger.
One breaks ground on your accessory lights to deactivate them triggered by the same accessory lights power.
One on the ground side of the LEDs gets triggered by a switched power like headlights and breaks the LED ground killing the LEDs.
Put a switch in that relay trigger to interrupt trigger power and restore LED ground when you want LEDs while switched power is on.
Use existing power for triggers and bring new power from the battery for powering LEDs. Use fuse.
A bunch of other ways to get the same result. That's a 20 dollar version.

We can't help it
We just keep moving
It's been that way since long ago
Since the stone age chasing the great herds
We mostly go where we have to go
