You said high and low, and I figured you meant beams. No matter.
The conductor probably doesn't need to be more than 28 gauge, really...its the insulation that matters. That's why I said that normal 300v (most automotive wire is 300v class at best) or 600v wire would be a bad idea.
I remember when neon under cars first hit the scene, back in about 92. Guys were just using regular glass tubes and transformers, like you would in a sign. They were also using regular automotive power and (gasp) speaker wire. Lots of cars burned down.
My guess (hope) is that Jriggs got some higer voltage cable. Back to the original question. If you get the right wire, and use the right connections (heat shrink won't do it, unless you use lots and lots...you really need an air gap.) you can extend the wires between the bulbs and ballasts, but if you can avoid it, I would.
