I'm not sure if that's what I'm running into or not. My lights are rather
buried in my castle, and I can't say I'm willing to dig them out right now. I
am running (if memory serves correctly) 8 or 9 lights off one box, and 4 of
those are the 'police' lights (1x4 brick, two lights on top that alternate), so
about 12 bulbs in total, running off 1 battery box through 3 9v wires, and a
number of the conducting plates.
All that being said though, I'm fairly certain that the big reason the lights
are dim is that Lego lights *are* dim. They just don't shed a whole lotta
light.
