Daytime running light uses up to 90% less additional fuel compared to driving with the low beam on. This was the result of an official study by BAST (Bundesanstalt für Straßenwesen = German Road Traffic Authority). In addition to the cost savings, this has the further effect of reducing CO2 emissions by roughly the same amount. This means that HELLA daytime running lights for motor homes and transporters are not only safer, but also more cost-effective and environmentally friendly, than conventional low-beam lights. If you also take the long design life of LEDs into account, the following becomes clear: HELLA daytime running lights are impressive not just due to their cost-effectiveness, but also their innovative technology.
