 >Will Halogen lights work on a dimmer?

The short answer is YES!  But, halogen is not the issue.

The problem is that there are a lot of low voltage halogen bulbs out 
there, and for that the answer is not so clear.

It is not whether the bulb is halogen or not, but whether the lamp is 
low voltage.  If the bulb is 120 volts (or whatever voltage the 
country uses) then a dimmer is fine.  But, the 12 volt bulbs (halogen 
or not), use a transfomer ( a coil of wire) or electronic ballast (a 
more modern, lighter weight type showing up more) to change the 120 
volts to the lower voltage for the bulb.

Some dimmers will work with the transformer type for a while, but 
tend to burn out quicker.  The electronic type is definitely a bad 
thing to put on a transformer.  It is like trying to dim a 
TV.  Electronics can't be dimmed.
