why does my voltage gauge drop using headlights
Why does my voltage gauge drop using headlights? There are two reasons for this situation. One reason is that the battery is seriously out of power . It is about to be scrapped and replaced with a new battery. Another reason is that the headights consumes a lot of power. I don't know what headlights you use . If the xenon lamp is used, many motorcycle friends will reflect this situation. After the xenon lamp is turned on, the voltage gauge drop greatly, and even the horn becomes dumb.
In addition, one more thing to add: the brightness of the halogen bulb of the original car is not enough . For the sake of driving safety , many riders now refit their lights. Now people usually use LED headlights . The LED headlights are very bright, which is more than four times the brightness of the halogen bulb of the original car, but they are very energy-saving .
The energy consumption is not only less than 60% of the halogen bulb of the original car , but also valuable : the LED headlights are started instantly and will light up as soon as they are powered on, There will be no delay like xenon lamp. It will light up slowly . The headlights are known as the third lighting revolution . Their invention is inspired by fireflies . In the future, headlights will also be popularized in household lighting .
However, headlights are used in DC vehicles . DC vehicles can turn on headlights without starting the engine. In addition, different headlamp wiring methods are different . Some are three wire , some are four wire.
Take the most popular "three side headlamp m3h" as an example. The green line of the headlamp is connected to the negative line of the original vehicle, the blue line of the headlamp is connected to the far light of the original vehicle, and the white line of the headlamp is connected to the near light of the original vehicle.
If the wire is wired , the headlamp will not light up, but it will not burn . Headlights are mostly protected by reverse connection of positive and negative poles. You can connect them at will and try them at will until they are on.
