Changing bulbs
Attention
When changing bulbs the vehicle ignition must be switched off
and the plug for the lights removed from the towbar electrical
socket. Failure to do so can result in a short circuit or other
damage. If you are not sure, have the bulbs replaced by a
specialist workshop.
Note
The lamp change is described and illustrated using the left tail
light unit on the bicycle rack. The procedure is the same for the
right tail light unit.
Note
When ordering a new bulb, you must specify which bulb it
is (14, 15, 16, 17).
