Landing & Taxi Lights Not Working

[PacNW Pilot]

Hi, all-
I've got a 2016 Sling 2 S-LSA. I'm trying to troubleshoot landing and taxi lights not working and looking for some assistance/experience.
Both lights stopped working at the same time; I noticed when landing one evening that neither switch would activate the respective light. The 15A breaker in the panel isn't popped/tripped, and the nav/strobe lights are working.
I physically verified good connections on the light fixtures themselves but haven't started continuity testing on the cable from the lights to the panel.
My best guess is loose wire at a connector between the cable in the wing and the cable in the fuselage but I can't say for sure.
Anyone more knowledgeable than me on wiring/electronics have more ideas?
Thanks in advance!

I was able to troubleshoot the cause back to a loose ground connection on the landing light. Connection has been repaired and both lights are working properly again. Yay!

Darn Grounds...

They are more often than not the problem...

Keep up the good work, and Happy Flying!
