What if the headlights fail at night?Night driving must pay attention to safety, appearance must not be nervous, what is the cause of the headlights malfunction?Headlamps is also called the "high", and its assembly is running one of the important parts of automobile safety, installed in the car on both sides of the head, used for driving road lighting at night, there are two lights and four lights system.Drivers and maintenance personnel for the sake of convenience, and the pursuit of headlamps luminous intensity, and some light in order to make the testing of the luminous intensity of headlamps e., reaching both to replace the original car headlamps light bulb with high power bulb above, the result is: the luminous intensity headlamps have been achieved, but greatly increases the headlamps circuit fault, sometimes also damaged the charging circuit.Most adopted four lights of the cars in the factory is equipped with a light bulb power of 45 w / 50 w headlamps, headlamps line points left and right 2 road, with every line of 15 a fuse insurance, cross-sectional area of 1.5 was, therefore, current of each line are within the scope of the permit, rarely headlamps circuit malfunction.After switching to a high-power headlight bulb, the current on each headlamp line is doubled, causing a severe overload in the headlamp line, which may cause the following faults.

1. The battery is seriously deficient.

In light after connecting the battery to collaborative generators, therefore, car at the start of driving at night around 2 h of the brightness of the headlamps in normal, and since then because of the battery can no longer continue to power supply, so the brightness of the headlamps to drop, and the changes over the engine speed, after the engine starter will not be starting the engine.

2, heat conductor, so that line of resistance increases, the luminous intensity of headlamps, serious when headlamps line short circuit because of wire insulation layer melt, even circuit burned or auto fire accident.

3. The contact of light relay or combination switch in the line produces ablation or bonding, so that the circuit cannot be disconnected or connected.

4. The fuse in the headlamp line is fused to make the front of the car dark.

5. When the electrical appliances are used more and the generator overload lasts too long, the diode and coil of the generator may be burnt out, so that the generator cannot generate electricity.
