Slow headlight

Anybody have any idea why one headlight has a slight delay raising and lowering.
Thanks Keith

Slow relay, poor connection inc. the ground?

Thanks for your reply NRG, I will check the wiring
Regards Keith

Seeing your post Keith reminds me of something I had forgotten from my teenage years Keith. We used to slide the light switch to on and off very quickly a couple of times and you could make your Ex wink. NRG is right, it’s got to be earth, I can’t add anything else, just reminiscing. Good luck

Thanks for your comments Andy, My lights wink without turning the switch on and off quickly.
Keith.
