LED indicators with failure check

Safe conversion to LED indicators ■

using patented Hella electronics

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.

The method has been patented by Hella. At the moment there are three different ballasts and several different LED indicator types available.

* Simulation of the filament bulb is deactivated for thermal reasons if the temperature exceeds 50°C.

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.

Vehicle conversion

Is there a fl asher relay built in the vehicle?

Switch on vehicle ignition, and remove a bulb from the indicator without pressing the indicator switch.

yesStart Is there a fl asher relay built in the vehicle?

no

Vehicle not ECE-conform

Failure of the fl asher unit is indicated yes

no

Solution 3: through LED indicator control unit

Solution 1: replacement of existing fl asher unit by LED fl asher unit from Hella with ISO pin basis

One fl asher 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.

One simulation unit per LED light necessary.

Failure of the fl asher is indicated

Press indicator switch

yes

no

Solution 2: through simulation unit for cold check

Two LED combination rearlights per vehicle can be monitored using one simulation unit. (Just on simulation device per vehicle can be used.)
