Ducati PANIGALE V45 2021 Owner's Manual page 66

DRL in "Manual" mode – only for version with
DRL lights
If the DRL lights are in this mode, as set through the
"DRL" function within the SETTING MENU, DRL
lights will not change their status upon key-on.
To switch on or off the DRL lights, it is necessary to
press button (2, Fig 36).
Attention
Using the DRL lights in poor light conditions
(dark) could compromise the riding visibility and
dazzle anyone coming on the opposite lane.
Note
Using the DRL lights during the day improves
visibility compared to low beam.
