Puzzling Sidelight/Tail light problem

[TOM VR46]

Wee bit late , but to answer Sharpshooter, yes you can take ignition apart. Thats where i had electrical problem once . Similar light problems . I found one of the wires had broken off. Wee solder job and still going strong.
As i remember there are two security screws that just need a wee slot cut into them for flat head screwdriver and all comes apart. Think i used the dremel for it.
When taking apart, keep bottom turned up and slowly take apart. Just take it slowly and all should be fine.
Im sure i posted pic of broken wire on here but not sure when.
