When hornby released the class 56 they were shipped with cool white leds, this is the wrong colour and should be a warm white led, this kit replaces all the lighting on the 56 to give that independent headlight control, and an led behind each lens instead of hornbys 1 led for all, 

This will also remove the horrible spring connectors between the body and chassis, giving more reliable lighting

This kit can be made to wire directly to the dcc decoder or to the original lighting
