Vibating nearside headlight at idle.

[1in7]

Has anyone got a cure for a vibrating headlight at idle. The nearside headlight tends to vibrates quite a lot and so the light flickers quite severely, but only at idle. The offside is fine. Ive tightened up the bolt directly under the headlight and even loosened it as tightening didn’t seem to improve it. Any ideas or is it normal due to the location of the K series engine to the light?

Are your engine mounts ok ??

Often the bezel that holds the glass unit in place - in which case blu tack works well but may take several attempts

What year is your car?

Probably resonance-just change your idle speed

This may not apply to your chassis, but check that the pointy grub screw that clamps the headlamp bracket onto the top chassis rail is really tight.

Check the rivets holding the bowl to the lower bits are still tight and holding - if they are loose, that'll make the bowl wibrate more than it usually will - you might have to replace a couple of them with nuts and bolts or temporaily push some epoxy or similar between the parts to tighten the gap.

Thanks Guys

SM25T. Engine mounts?! – that’s a scary thought. But being new to the fold I guess that should be a regular check anyway?

sforshaw the year is 2007.

Paul McK. It definitively disappears with slightly higher revs. What’s the idle rev range? Any ideas?

John. I ll double check that end of things

Bricol. It is the whole unit that’s vibrating so does appear to be that but thanks.

That’s given me some pointers though thank you.
