New high quality H4/HS1 6V DC LED bulb The bulb was created with historic motorization in mind. It is distinguished by a warm color of light and can work both in the "-" and "" system on the ground with a voltage of 6 V DC. In the case of vintage vehicles, LED bulbs are, apart from much better light, an additional advantage in the form of low power consumption, which in the case of low-power generators is of great importance. The headlight bulb has the function of low beam and high beam. The change of light is ensured by the appropriate arrangement of the diodes. The bulb does not dazzle oncoming drivers! Specification : actual power consumption 13W voltage 5-9V DC warm light color 4300K the amount of light is clearly greater than a traditional 60/55W bulb socket H4/HS1 I recommend!!! Issues in the field of electromechanics often cause problems for my clients. That is why I always offer advice both in the field of electromechanics and the selection of LED bulbs and voltage regulators for all popular vintage vehicles. I am also happy to talk about rare vehicles. I advise against choosing whole sets on your own. Low beam High beam
