Higher voltage means hotter filament meaning more light.
The filament resistance goes up with temperature, so it does change with voltage.
While I think this thread should be titled "lights. Lots and lots of lights." having multiple lights is good for visibility, but having them spaced out makes good sense, I wouldn't put them all in middle of the bars.
