Ducati Diavel Service Manual: Electrical power for lighting and signalling devices

The front and rear running lights consist of led units with light conduits. As a result, the light source is not visible as the light is diffused through the surface of the light conduit.

To access the tail light - turn indicators unit, remove the seat as described in sect. 5 - 3, "Removal of the seat" and the tool tray cover as described in sect. 7-17, "Removal of the tool tray".

The bbs and the dash board unit provide electric power to the lighting and signal devices, which therefore have no conventional power supply passing via a fuse and no electric switchgear set on the handlebar. Commands for the lights and signals are in fact sent to the control units, which then activate the relative lighting devices. The following table indicates the types of devices used, the type of power supply and whether or not the devices are testable.
