Fog lights not always turning on, not the switch! Any ideas?

[ARNIE R]

I have recently been having issues with the fog/driving lite option in which they sometimes turn on with the switch and more often, they do not unless I cycle the switch several times.

So, I figured maybe the switch was defective and needed replacement.

I also have some Tricled ring lites wired separately to an identical switch so I swapped wires and tried that, however, the driving lites still will not come on, so a defective switch is not the culprit.

Checked all fuses and did not find any blown units. All other bike functions work fine.

Anything else I can check on next?
