Lighting system
When riding on public roads a properly functioning
lighting set is obligatory (see the chapter “Legal
Requirements for Riding on Public Roads”).
You should be familiar with the assembly of the
lighting set so that you can repair possible failures
yourself.
The rear light
(e)
and the front lamp
(f)
are powered
by the generator (also referred to as a dynamo). They
are connected with two cables each to the genera-
tor. In some cases the front lamp and the rear light
are wired with only one cable each the frame being in
this case the return line.
Rear light
Either bulbs or LEDs beam through a (red) diffusion
disc rearwards and are visible at best even from the
side. Nowadays most rear lights provide a stand light
function that is powered by a capacitor or a battery
when the CENTURION bike has to stop at traffic
lights, for example.
Front lamp
Illuminants are either bulbs, halogen lamps or one
or several LEDs, i.e. light emitting diodes, beaming
white light by means of a reflector and/or a diffusion
disc on the road lane.
Some models are fitted with a sensor that automat-
ically switches on the front lamp when it gets dark;
the dynamo must, however be activated. An addi-
tional feature of particularly high quality front lamps is
a stand light function or even daytime running lights
(both with LEDs).
Hub dynamo
Hub dynamos
(g)
are built into the hub of the front
wheel. They are virtually non-wearing and extremely
effective. Some models are switched on electroni-
cally, some others mechanically. Hub dynamos are
either switched on by a lever at the handlebars or
directly at the front lamp. Other models offer the con-
venience of being switched on and off automatically
by means of a sensor.
