Many traffic accidents - not only during nighttime - are caused by late or failed recognition of moving vehicles. Daytime Running Lamps (DRL) lead to better conspicuity and thus helps to reduce traffic accidents. This has recently been confirmed in a study by Koornstra, Bijleveld and Hagenzieker [1]. Nevertheless, the extra power consumption and its environmental impact is often used as argument against the general introduction of mandatory driving with lights. We have investigated possibilities of how to realize DRL with low power consumption. Several reflector concepts have been analyzed. Existing bulbs have been considered as well as some new developments.
