Excuse me. Maybe I'm the only one who sees the obvious here.

If you have a short and you're using the light what do you think is 
going to happen? Do you think the wires are going to melt? Do you 
think you'll explode? Have you ever thought about the OBVIOUS fact 
that your filament will burn out thereby breaking the circuit because 
the bulb will work like your fuse?

There is NO valid reason to have a fuse in a light. The charger won't 
work when there's a short, and the bulb will blow before anything 
really bad will happen with a short. The only reason to have a fuse 
in the light is to try and fix a non-problem, which just adds a new 
problem by itself.

Think it through.

Ken
