The breaker you described is called a twin, two seperate breaker handles in one space.
It sounds as though you have a loose connection somewhere, if by surge, you mean going dim. (if this is the case, it should be resolved soon) Start at the breaker and feel if it is warm, or hot to the touch, this would indicate a loose connection in the panel. If not, and only if you feel comefortable doing it. Start at the nearest light fixture to the panel, (turn the breaker off first) take the light down and check for loose wirenuts. Also check any light switches associated with these lights.
I can only help so much online, if you aren't comfortable checking yourself I would definately have a qualified person take a look at it.
Hope this helps, Gabe
