The rear tail lights of the car are not good, why are the other lights also on?

Because it is shared with other lights, it was originally through the loop of the wire to make the rear tail light on, because the tie is not good, its circuit will pass through other lights, such as through the turn signal, because the rear turn signal and the front turn signal and the turn indicator of the instrument are connected together (of course, it refers to one side), that is to say, the tail light line does not tie the iron and pass through the rear turn signal bulb to the front turn signal bulb, because the front turn signal bulb is good, So it's through the front turn bulb. It can also be seen that the front and rear turn bulbs on one side are connected in series with the tail lights, so the brightness of the bulbs is darker, because the voltage of the battery is divided among the three bulbs. In this case, as long as it shares a tie wire with the tail light, it will generate a loop.

Each lamp has a separate line, and the design cannot allow one lamp to be bad and other lights to be bad. If you are asking about the brake light and the width indicator light in the back, these two lights are a bulb, there are 2 filaments in the bulb, these 2 filaments are connected to different circuits, when you turn on the light, only the filament of the width indicator light is on, and when you step on the brake, both filaments will be on. When the lights are not turned on during the day, only the brake filament is lit when the brake is applied.

If you take a brake bulb and look at it, there are 2 metal tentacles on the rear shell of the lamp, which are connected to the 2 filaments in the bulb.

Check out the other lines and estimate which line is short-circuited!

Hello dear! The function of the rear wing of the car is to make the air resistance form a downward pressure when the car is driving at high speed, try to offset the lift, effectively control the downward pressure of the air flow, reduce the drag coefficient accordingly, and increase the high-speed driving stability of the car; The tail wing is next to the Qi Dou is a brake grinding headlight, and there is no running light behind it! The lights only come on if the headlights are on.

Dear, I hope mine can help you, in addition, you can click on my avatar, follow me so that you can click on my avatar before you have any questions in the future for consultation, thank you for your support, look forward to meeting you again, I wish you a happy life!

The ground wire of the rear taillight is a black line.

What is the purpose of the rear tail light grounding wire:

The ground wire on a car means that the negative pole of the battery is connected to the car body. Of course, the whole car is basically charged. The electrical appliance is installed on the car body, and one end is connected to the positive pole. The negative electrode is turned on through the body. The ground wire (negative pole) is where the body is connected.

What does ground mean:

The ground wire on the car refers to a kind of current loop. The power supply comes out of the positive pole of the battery, passes through various switches, passes through the electric actuator, and then returns to the negative pole of the battery through a return wire, forming a cycle that causes various reactions and effects on the electrical appliances. The single-wire system used in the car is used, that is, most of the wires basically come from the power supply, and the return wires of various electric actuators are basically not directly connected to the negative electrode of the battery, but indirectly back to the negative electrode of the battery through the metal body of the car itself, but.

Brake lights:

The brake lights are two tail boxes, one on the upper part of the rear window, and the upper part of the rear window is called a high-mounted brake light, which is the same for both hatchbacks and sedans.

There are two types of lights in this group.

Situation 1 When braking, the high brake light and the rear brake light will light up together when braking.

Situation 2 When the width indicator light is turned on, the rear brake light is the function of the width indicator light, and the high brake light lights up when braking, and the rear brake light will increase the brightness.

Reversing lights: two for the sedan and one for the hatchback, on the right.

Fog lights Two sedans and one hatchback, on the left side.

The machine filter is the oil filter, and the oil must be changed every time you change it.

The oil grid is the filter.

The air filter is an air filter, which is replaced according to the environment and atmospheric conditions.

The air conditioning filter is the filter device for the air intake of the car air conditioning system, and in the center console next to the accelerator pedal in the driver's seat, if it is dirty, it will cause the air volume in the car to become smaller.
