The car lights do not light up when turned on high and low

Indicators and lighting lights are important when driving, especially at night or in foggy or dark weather with low visibility. The lights on or off are a sign of safety. The following will analyze and explain various situations and solutions for car lights:

Steps/Methods

1

The headlights do not light up at night

At night, if the headlights are not on and you cannot drive on the road, first check whether the fuse is blown. Turn on the headlight switch, and the high and low beams are not on. First check whether there is a blown fuse in the fuse box, and then check whether there is any reason for the drop between the car light switch and the dimmer switch.

Use a screwdriver to connect the live wires of the dimmer switch to the far and far beam terminals, and use screws to connect the live wires of the dimmer switch to the far and low beam binding posts respectively. If the lights are on, it indicates that the dimmer switch is malfunctioning; If connected, the far light will be bright. Low beam is not bright. The fault is between the dimmer switch and the headlights or between the low beams. If the headlight high beam does not light up, check whether the high beam indicator light is on. If it is on, it indicates that the fault is between the wiring board and the headlight. If it is not on, it indicates that there is a fault between the wiring board and the dimmer switch. If only one headlight is on and the other is not, it may be that the filament is burned out or the wiring is broken, or the grounding is poor (the headlight brightness is weak).

Light bulbs often burn out

During the use of bulbs of large and small lamps, the filaments often burn out. The reasons are: the voltage regulator is faulty, the voltage Too high; the battery wires are in poor contact, causing the generator's no-load voltage to be too high; there is a short circuit between the generator armature and the magnetic field coil. If you turn on the light switch and the bulb burns out immediately, you should check whether there is an open circuit between the charging lines. If the bulbs often burn out, check whether the generator voltage regulator voltage is adjusted too high.
