Solution 2:
simulation unit for cold check
The method has been patented by Hella.
At the moment there are three different ballasts
and several different LED indicator types available.

Solution 1:
LED flasher unit
LED indicators
Solution 4: Light control unit
with integrated failure pulse
In the future, light control units will be able to scan the failure pulse.
This makes interim solutions 1 - 3 no longer necessary and
communication can be directly with the indicator lights.

We offer electronic ballasts for the Hella LED
flasher lights which makes it possible to convert the
indicator failure display for variousvehicles. This is
necessary if the vehicle manufacturer does
not guarantee indicator bulb failure checking
via the vehicle electric system.

Vehicle conversion
Is there a flasher relay built in the vehicle?
yes
no
Switch on vehicle ignition, and
remove a bulb from the indicator
without pressing the indicator switch.
Failure of the flasher is indicated
yes
no
Press indicator switch
Failure of the flasher unit is indicated
no
Vehicle not ECE-conform
Trailer conversion
Solution 1: replacement
of existing flasher unit
by LED flasher unit from
Hella with ISO pin basis
One flasher unit per vehicle necessary. Every possible combination
of bulbs and Hella LED indicators is allowed: from complete equipment
with bulbs through mixed versions to complete equipment with LED
lights. Bulbs or Hella LED indicators are also permitted on trailers.
Solution 2:
through simulation
unit for cold check
One simulation unit per LED light necessary.
yes
2BA 959 050-401
Solution 3: through
LED indicator control unit
Two LED combination rearlights per vehicle can be monitored using one
simulation unit. (Just on simulation device per vehicle can be used.)
