This Upgraded Circuit board is for the Hornby DVT and is a direct swap out from the existing board but it enables the center Lights to be REAR/MARKER and the Day running light illuminated. This is different from the factory release which had the side markers lit.
This will require cutting of the clear light lenses to the markers, so the light dose not emit to them ruining the effect.
Like hornby's newer models this kit doesn't come with the contact springs so wires will need to be soldered to the back of the board
Full Fitting instructions are included.
