Engine/Tender LED Lighting


General Description

Engine LED lighting for all types.  Can be used in Steam, Electric, and Diesel.  The LED kits are great for the headlight, markers and tender backup light.  These are Royz Trains products made especially to work with the ERR Commander/Cruise Commander units.  However, will also work in conventional mode with constant lighting.  All work with either track voltage or direct from any commander board.  The boards come with double-sided sticky tape.  The input on each board has a capacitive load to ensure proper operation with all ERR Command units.

MARs Kits

These provide a very realistic looking MARs light via a single 3mm LED and can also drive an additional headlight LED as may be found in a F7 or Daylight engine (and others!).  The basic kit requires a well regulated 8 VDC supply (or greater voltage).  An optional supply is available to use AC track power or connection to any ERR Command unit.  The MARs simulator board is 3/8″ square and you may choose to purchase all the components fully assembled and ready for installation including two 3mm warm white focused LEDs.  These LEDs do not have a shoulder like most to allow easy insertion into the typical headlight housing.

Single LED Kits

These kits include a single focused 3mm warm white LED and supporting power supply.  May be used in steam, electric or diesel engines.  The LED simulates an incandescent lamp with constant brightness at all track voltages above 8 VAC (illumination starts when transformer supplies power).  The result is a focused beam that projects on walls and diminishes until the engine makes a curve.  Don’t get much more real than that!!

Dual LED Headlight Kit

This kit includes two focused 3mm warm white LEDs, supporting power supply, and connectors.  Ideal for those diesels that have dual headlights front or rear.

Electric Engines

Electric Engines with single lamp housing at either end should use two of the Steam Engine Headlight kits.

Dual Red LEDs

This kit is used to add rear markers to a tender or passenger car without existing lamps.  It include two 2mm red LEDs and supply.  If you are looking to replace existing red bulbs and/or you have actual markers on the rear of your tender, you want to choose the Dual Ceramic Red LED kit.

Number Board LEDs

This kit provides a low level warm white LED to be mounted behind a number board.  Typically only diesel engines have the room behind the number board to allow for this addition.

Steam Engine Green Markers

Two ceramic green LEDs provided to replace earlier red LEDs many manufacturers incorrectly provided.  Supply included.



A two pin connector is supplied for tenders and diesels where the body may need to be separated from the chassis. Each power supply has double sided sticky tape to facilitate mounting.  The foot print is 0.9″ x 0.6″.  The supply input is normally connected to the Front/Rear outputs of the Cruise Commander or regular Commanders; Common screw connectors on a command board.   However, it may also be connected directly to track voltage.  Instructions provided.
