Headlight level warning light

Hey guys

Anyone care to shed some light on this.. on/off ive had the headlight leveling warning light flicker for months now.. seems to be on more than off now a days.. both sensor arms under arch seems free and ok.. no obvious water damage in the connectors.. im reluctant to take it to dealer - might just ask me to replace everything lol.

Thanks

Mine was doing this for quite a while a few months ago, then headlights adjusted themselves so beam was pointing down towards the floor and light then stayed on permanently, I got it checked out and it was the front sensor on the front suspension, got a second hand sensor and got it fitted it's been fine ever since, the new sensors are a fortune from a main dealer
