oh good catch! By "overvoltaged", do you mean that the bulb draws more than the voltage stated on the package??
With my 5w light, oncoming cars dim my view of the road. Opps pothole spotted at the very last second! At 20mph, I figure I'm going about 30'/second. Need a set of lights that'll throw about 100-300' of light. Narrow beam is OK Would like a battery that weighs about 9-16oz (like that 19V/3.9A)
Which bulb can do that? How much throw does your new setup have?
