Vehicle headlight discharge circuit, has one switch to send correct voltage based on value for long-distance/short-distance headlight, and two switches for high voltage regulation of short-distance and long-distance lighting of headlight

摘要

The circuit has a DC/DC conversion switch (3) connected with a Hi/Low switch (5) that receives an output voltage from a switch (2) for automatic detection of a voltage of a long-distance/short-distance headlight. Switch (5) sends a correct voltage based on a value for the headlight. A switch (6) and a switch (7) are provided for high voltage regulation for short-distance and long-distance lighting of the headlight, respectively.
