need advice and tech specs information

[jtf027]

Can anyone tell me how many amps the motor on a single MX intersection light draws ?


I want to power one of these motors at 6volts DC instead of 12volts DC, in an attempt to slow the oscillation of the head. I understand that the bulb would have to be powered separately at 12volts.


What I cant figure out is how to reduce the voltage safely from a 12v DC power supply. Im not great with electronics and schematics, so if anyone might be able to build this, let me know as well.


Thanks

First off, check out this thread. Lots of info

Next. The main amp draw in the halogen bars is not the motors, it's the bulbs. Use smaller watt bulbs, say 20-25 watt or less rather then the 50-55 watt.

I appreciate the reply, but Im not trying to power 12voltsDC from 120vAC, im trying to REDUCE voltage from a 12vDC supply to power a motor off 6vDC. Ive already alleviated the problem of the high amp draw from the bulb by rewiring the bulb to a constant 12v supply, but now i still want to slow the oscillation down using a lower voltage supply. The resistor research is why i needed the MOTOR amperage.
