Connecting Lights (Leds) - M.T.H. Proto-Sound 3.0 Installation Manual

Connecting Lights (LEDs)

- Install the Ditch, Headlight, Marker, Mars, Overhead Blinking, Cab Interior,
Number Board & Back-up lightbulbs into the proper engine & wire harness
locations as seen in the diagram on page 16.
- On RailKing diesel locomotives, the headlight and backup light are usually a
screw or bayonet based bulb inserted into a bracket mounted to the chassis.
This bulb must be replaced with headlight bulbs (D&G) in the kit in order to
have constant voltage, directional lighting. Secure the bulbs in place with tape
or hot glue. Do NOT wire the existing bracket and bulb into the Proto-Sound
3.0 harness. It will damage the lighting circuit.
