Hi, I own a 1998 416 SI and the right side front indicator light keeps falling out, it seems the light fitting is too small for the cut out in the car. Any help would be much appreciated.

It usually screws in just near the top of the headlight.
There is more than likely damage to the indicator.

Yep, as above. Just had a look at mine. There is screw at the top of the inner wing accessed from the engine bay .

As above, time for a new one..
