Faulty head light

[lizmorton]

I have a problem.My drivers side head lamp keeps comming away and hence the light and indicator stops working untill i push it back.I carnt locate how i take out the unit to check see if it is a broken clip or something.I dont want to take it to a garage yet incase there try telling me its a bad problem that will cost a lot when it could be something simple.
Any help would be much appreciated.
thanks liz

thw whole headlamp cluster winds in and out as a whole. I think there is something you need to turn/rotate with a spanner or screwdirver. It may not be wound in all the way.
