In my Piper Arrow (the original Hershey bar wing, 180hp version), the left main gear indicator light is dim, maybe 1/4 the intensity of the other two lights. Moving the bulbs around keeps the dim light at the left main position. Turning on the nav lights dims all three indicators further, so I don't think it's somehow failing to undim the left main light. I have not noticed any flicker or other weirdness. Other than pulling all new wires to diagnose with my checkbook, does anyone have suggestions for causes to rule out?
