Daytime Running Lamps with Low Power Consumption 970908

During the last few years the function of daytime running light (DRL) has been applied more frequently. According to road safety experts it is an important factor in reducing daytime collisions. The number of countries allowing or requiring the DRL continues to increase. A frequent argument against DRL is the increase in fuel consumption caused by the rise in power consumption.The development target, therefore, was a separate daytime running lamp, which would have a reduced power consumption in comparison to the low beam function frequently used.A prototype with an approved light source was to be developed to allow immediate series production.The increasing quality standards in the automotive industry are also challenging for the component life of the bulb. With the optimisation of the “bulb - lamp” system, new concepts may be introduced, which will comply with future component life requirements.
