The 125 has replaced the 123. The 125 is smaller and has Bemf compensation.

ok so what is the differnce between the 123 and the 125 ?

I used a DIgitrax DZ125. It was actually a pretty easy install. I used the original light board and cut a couple of trace lines on it and removed the brass strips that contacted the motor brush caps. I placed the DZ125 underneath the lightboard with a thin piece of cardboard under it to hold it up. I used a couple of shortcuts - I only used the one resistor on the light board for both headlights(the disadvantage to doing this is the headlights are dimmer when both are on at the same time) and I did not solder the orange and grey wires to the brush caps, I just globbed the wires up with solder until they fit tight when pressed into the holes in the caps.
