Your absolutely right. Mine do rub a little with the rear turn signals. That does not bother me at all. I plan on switching out to the integrated tail light unit in the near future. Btw I put 15 pounds in each side and rode for 30 miles just to check if it would be affected by the weight good news no problems
I was wondering is I could ask you a question regarding your viking bags? I ordered the same ones but they seem to interfere with the rear turn signal lghts. Yours seem to ne ok. Did you have to alter something to make them fit?
