Took the car out for a good run around and shakedown following a long winter lay off. The Chrome rim on one headlight came adrift when i went over a big bump. Stayed attached to the car by the screw at the bottom. I put it back on but at the next bump it came adrift again!!! Has anyone got a way of putting a screw in the top to stop it coming off? Do these wear over time or could the fault be with the plastic lamp surround to which it attaches?
