Funny thing happened last night. I went out to the car at around 6pm, unlocked the car and expected the lights to come on, but they didn't. Got in, started the car and the headlights light up (switch set to Auto). Turned off the engine, got out, locked the car, unlocked the car, but no headlights again. So locked it again, held my hand over the light sensor, unlocked it and low and behold the lights came on. Tried it again without covering the sensor and guess what? No lights. Started the car, lights came on, thought "feck it" and fecked off.
