Pair of circuit boards to replace the existing Bachmann boards which have Yellow LEDs as cab lights
Will require unscrewing the light board and remove the top marker light plastic housing and fit onto the new board. This uses the existing 4 wire cable harness onto the main PCB and will require a small amount of soldering the wires to the new board.
The board also have a screw variable resistor to increase or decrease the cab light intensity.
Only Suitable for 21 Pin Models
