I've been out this eve so just read thru the thread. John C seems to be reporting an almost identical problem.
But I will address the suggestions of bad earths first. My checks started with that assumption although the symptoms didn't seem to fit.
in fact the front sidelights are well earthed at the front of the car and I couldn't see how and earth fault could do anything other than make them fail to come on properly, or at all, They share an earth with the 36W headlights which work OK.
I only have the two examples of the stop/tail LEDs which were cheap Chinese "corncob" types off eBay. It's quite possible that all the advertised ones are not all the same - and some types I see illustrated there have two quite separate LED element is the "BulB" These would probably not be affected.
Tomorrow I will test my examples more thoroughly and satisfy myself that current is back-feeding from the other (tail) pip
It's too late tonight to see if my particular examples can be made serviceable with the inclusion of a diode(s). I'd need to get my head around exactly where to insert it after satisfying myself what's going on..
meanwhile it's good to know that this effect has been seen elsewhere..Roger
