What is HI/LO? bi-xenon?


On some other vehicles, the headlights have one bulb each. This bulb performs the function of both the high beam and low beam. In this case, if you want to keep the high beam and low beam functions, you will need to install a special HI/LO kit. The HI/LO HID kits have special bulbs that perform both high and low beam functions.
