The FRED can be powered by a 9 volt battery, fixed voltage
(6-20 volts) AC, DC, DCC, or by track power. The electronic
circuitry produces a high intensity flash of an ultra bright red
LED and is usable as an "end of train" device, on top of water
tanks, towers, ambulances, fire trucks, locomotives, caboose's
or other applications. They will fit HO and larger cars.
The FRED is furnished with double sided mounting tape and
includes wire leads with a 9 volt battery clip installed. For other
power sources simply cut the battery clip from the wires. If an
on/off switch is desired, item #524 does the job!
F.R.E.D. stands for Flashing Rear End Device.
