TR6 Tail lights

[Charlie Frazer <cfrazer@ballmer.uoregon.edu>]

Can some one help me with TR6 rear turn signals?
When I flip the turn indicator, the front lamp comes on and stays on.
Nothing happens in the rear.
If I put the turn signal on and wiggle/twist/pull the socket in the rear
lamp, in some positions it will flash.  
The bulb is OK, and I've carefully cleaned each leg of the socket to insure
good contact.
But it still will not work reliably.
Thanks for your suggestions.
