The plug-in LEDs for 5V herald the next generation of front lighting. For the first time, a series-produced, retrofittable and easily pluggable warm white LED is available for headlights. The legally protected miniature circuit boards with specially specified LEDs are the perfect replacement for a light bulb with its round, warm white light spot. There is no visible difference. Power savings and the significantly longer service life make the LED the more cost-effective light source compared to conventional light bulbs.
