Never a problem on any of the ones I've done, or of those I've personally known.
That does not mean it couldn't be a long-term issue, but I have just not run across it before.
It's a standard Ford switch too, from what I remember. So you could try another one from a local supplier to see if it's just a QC issue with whoever makes Centech's switches for them.
I can't remember, but believe it's just an '80's truck switch? You could take yours down to the local parts store and compare easy enough I would think.
But also, since it's effecting two switches of such wide purchase dates, you might inspect the main connector much more closely as well.
It may have a fault in it that's not letting one wire connect fully perhaps. Or the one specific wire is on the wrong contact point.
I don't know if it carried over to later switches, but the early switches were common across the manufacturers in one respect. On early (pre'68?) versions the wires went to one available terminal, while on later ones it was moved over. That one wire was for the front running lamps, so it should not effect tail lamps, but you never know.
The idea was that early vehicles had front marker/running lamps that were on only in the first position of the switch, then went back out when the headlights came on with the second click.
Later when the laws changed, they kept them on, but kept the switches so they could be used on older vehicles and work as expected.
Good luck. Strange issue for sure.
