It's worth a try. I had a red LED I wanted to put into a mount so I could see if motor was on. I also didn't want to draw too much from the batteries that drive it - 3xAA. I had a choice of voltages from inside the unit - I finally went straight across the motor - 1.78 volts. The LED just glows (but will be easily seen in the dark) and is drawing only 0.4mA (!). But I think the specified min voltage for this LED was 1.7 volt, so I'm still above this.
