These are not halogens. Where can I get information on DC choppers? I've not
heard of them before.
Thanks

A DC chopper reduced the voltage without producing heat whereas a rheostat
merely provides resistance and builds up heat.  I had a rotary chopper switch
on my boat to dim overhead 12 volt lights in the main cabin.  However these
were incandescent bulbs and I do not know how or whether they would work with
halogen bulbs.

Well, you cannot use a normal SMITHS rheostat, it just has not got the

wattage and will burn out instantly, causing a fire hazard. Anyway you

cannot dim halogen bulbs very well as they will wear out very quickly.

Just adjust the hight so you will not blind oncoming traffic or yourself

in thick fog.
