Frustrating turn signal

[curvedglass]

Recently my right front turn signal on my 63 went out. I noticed the indicator light wasn't blinking on the dash so I did a visual and saw that one was out. I replaced to bulb and still nothing. Now the parking light is out as well. Also to confuse matters, the indicator doesn't turn on for the left signal either - but they work. Front and rear. Right rear is also working. I traced the wire to the harness and no visible cracks or splits. I can hear the relay clicking. Could it be a ground for that one light? Electric is my Achilles heel.

Any thoughts, similar issues??? Any info would be helpful.

Thanks!!
