Front lighting problems with O gauge Dapol class 08 with ESU Loksound 5 58429

[Falcona4]

Hi, my local DCC installer is having some trouble getting my new Dapol O gauge class 08 shunting lights to work at the front of the loco.  Sound, top headlights and rear lights are working fine. To the rear of the motherboard there are two plugs connecting to both lower and upper lights, which work fine. On the front there is only one plug connecting to the upper light, which works and we can see the lower front lights wired up as well, but we cannot seem to turn them on. Has anyone encountered this problem? On the instructions FO is listed for directional headlights, which do work. No joy from asking Dapol so far....is it perhaps something on the Dapol motherboard.

Has your installer checked which decoder output the lighting is connected to ?    If the loco has four lamps, and independent control is required, then it needs four connections to the decoder, and the usual default decoder function mapping of two outputs to FnKey0(fwds) and FnKey0(reverse) will only work two of them.      Assuming the lights are on different decoder pins then a function mapping change is likely to be needed to move the lamps onto whatever function keys are wanted.
