<VV> problem rear lights one side

[John Kepler]

I am experiencing outage of all rear lights on the passenger side only on my 65 Corsa.  Only rear light on the right side that is functional is the back-up light.  Is there any particular place that I can go looking for a bad connection that would affect the right side rear lights?  I really do NOT like electrical/wiring problems !! 
Many thanks 

Check/clean the ground for that side.  To test, simply provide a ground-jumper and see if anything lights!
