HO Scale, all metal searchlight signals - just like the prototype. The signal head will accommodate our Tri-color LED. VERY Detailed instructions are included along with painting and finishing tips and a history of searchlight signals. These signals are based on Southern Pacific prototypes but can be found on other rail lines. The kits contain a brass target that has been stamp formed - again - just like the prototype. For customizing your signals, see our Signals Details package. Also, a set of Drill Bits is available on the TOOLS page to aid in construction. The kits contain parts to make single, double or dwarf versions. LEDs, if desired, must be ordered separately.
