Winter is a period of high incidence of smog. Excessive PM2.5 values ??will seriously affect people's health. The turbid atmosphere will also reduce visibility and also affect the driving safety of all types of transportation. As a traffic participant Readers, we all hate rainy and foggy weather. Today, let’s talk about the common sense and modification of vehicle lights.
Generally speaking, the front lights of the car include small lights, headlights (headlights), cornering lights (with emergency light function), anti-fog lights and daytime running lights, while the rear lights consist of small lights. , brake lights, turning lights, anti-fog lights, license plate lights and high-mounted brake lights. The vehicle configuration determines the number of lamps. The switches of these lamps are generally located on the combination switch under the steering wheel or on the instrument panel to the left of the steering wheel. The high and low beam conversion of the headlights and the cornering lights are controlled by the left lever of the combination switch. These functions are detailed in the vehicle manual. introduce. If the vehicle is equipped with automatic headlights, it is recommended to keep it in automatic mode at all times. When the driving computer senses that the light has dimmed (such as entering a tunnel), the small lights and low beams will automatically turn on to prevent the driver from being distracted by the operation.
The function of headlights is lighting, and other lamps mainly serve as reminders and auxiliary lighting. Taofa has clear regulations on the use of various types of lights. The small lights mainly reflect the width and length of the vehicle, the brake lights indicate braking, the turn lights indicate that a turn or lane change is imminent, the emergency lights indicate possible driving conditions, and the daytime running lights and anti-fog lights make your vehicle more eye-catching.
High/low beam lights must be used and switched reasonably. Low beam lights should be used when meeting cars, in bad weather, on obstacle sections, pedestrian sections, and in good lighting environments; when driving at high speed under lighting conditions, High beam can be used on open road sections with poor environment and switched according to road conditions, oncoming vehicles and pedestrian status.
The front fog lights of the original car are mostly the same white light source as the headlights, while the rear fog lights are red light sources. The brightness of the front fog lights can indeed auxiliary lighting, but their most important role is to enable Other vehicles or pedestrians find themselves at a long distance. Since the anti-fog lights have strong penetrating power and will be very dazzling to oncoming vehicles and pedestrians, they cannot be turned on in normal weather. Therefore, the front fog lights of most vehicles need to be turned on. The lights can only work after the small lights are turned on. The prerequisite for the rear fog lights to light up is that the front fog lights are already on.
Many friends are very confident in their vision, so they do not turn on any lights when the light is dark. However, not everyone’s vision can reach 1.0 and above, which increases the risk of accidents. In this case, the main purpose of turning on the lights is to be eye-catching and to allow surrounding vehicles to spot you in time. When the light is dark, you should turn on the small lights (please ignore automatic headlights or daytime running lights) and low beams in sequence, and switch between high and low beams according to the driving status; when encountering rain and fog, you should turn on the small lights and low beams in sequence. lights, and switch between high/low beam according to the driving status. At the same time, the front and rear fog lights and emergency lights should be turned on. Do not turn on the high beam at this time, otherwise the eyes will be completely white and the visibility will become worse.
For an off-road vehicle, it often accompanies us to travel through mountains and rivers, and the driving conditions, environment and weather are unpredictable. At this time, the performance of the original vehicle lamps may seem inadequate, and the styling may be mediocre. Therefore, various modified lamps have appeared. Next, we will take the Wrangler JK as an example to introduce the modification of auxiliary lamps. Of course, cheap copycat products are not part of our topic.
The headlights, taillights and turning lights of the Wrangler JK can be directly replaced with LED lamps. High-quality lamps are not only more beautiful in shape, but also have the advantages of energy saving and high brightness. Because these lamps are original The parking spaces are interchangeable, so there is no need to consider matching, stability and safety. The front and rear bumpers of the Wrangler are almost a must-modify item. The shape, structure and function determine the quality of the bumper, but often people ignore the lights on the bumper. These auxiliary lights are the finishing touch.
The current LED auxiliary lights mainly have three irradiation methods: astigmatism, spotlight and combined light. Astigmatism irradiation intensity is relatively low, the irradiation range is wide and dispersed; spotlight irradiation intensity is high, the irradiation area is small and More concentrated; the lamp beads of the combined light are a combination of the two, so they are more balanced.
According to the color of the light source, it is divided into three types: yellow light, red light and white light. Yellow light and red light are used as anti-fog lights because of their strong penetration and eye-catching power, while white light is more suitable for auxiliary lighting because of its high brightness; as for the commonly used sizes: 2, 4, 6, 10, 20, 30, 40, 50 inches are available in double row, single row and arc shapes.
The front bumper should have one set of white light spotlights/yellow light fog lights. The spotlights should use combined lights. Since the power is relatively large, each group of spotlights should have separate wire harnesses and wiring starting from the battery. switch, try to avoid docking with the original car lines to avoid affecting the original car lines and functions due to problems with the lamp components; fog lamps should use yellow astigmatism, because the original car fog lamps are replaced and the power is small (original car fog lamps are generally 50W/piece, LED lamp beads are generally 3-5W/piece), so they can be connected to the original car's fog lamp wiring harness, and the original car's switch can be used for control; the rear bumper should be equipped with red and white astigmatism, just like the front fog lamp, and can be reversed with the original car The lights and the rear fog light wiring harness are connected so that the control function of the original car can be used. When reversing, the light is white, and when the rear fog light is turned on, it switches to red light. For models without the original rear fog light, the wiring harness and switch need to be arranged separately like the spotlights. .
There are also some precautions when installing an auxiliary light. It is basic common sense to handle it with care. External bumps may cause its internal components to become loose or damaged, and the probability of non-lighting, flickering, and abnormal noise is greater; The direction and protection of the wire harness reflect the meticulousness. Reasonable use of corrugated tubes and electrical tape to wrap the wires can avoid grounding due to damaged wires. Try to follow the original car wire layout for better fixation. Relays and fuses should be fixed in positions that are easy to maintain. , when leading wires into the car, do not damage the wire rubber ring to eliminate the risk of water leakage. If necessary, apply sealant and try to stay away from high-heat components such as exhaust, water pipes, and air-conditioning high-pressure pipes to reduce heat generation;
Line The accessories, cutting and docking require a little bit of electrician knowledge. Relays and fuses (included with the complete set of lamps) need to be selected according to the power of the electrical appliances to avoid being unable to protect against short circuits. Multiple wires in the same group should be cut staggered. , to avoid excessive local volume caused by the concentration of joints. It is strictly forbidden to cut the wire at one end of the lamp to avoid damaging the seal and causing water to enter the lamp. Electric iron should be used for welding when docking to avoid poor contact and heat generation.
There is actually no technical content in lamp modification, but modification errors may cause abnormal operation at the least, or may burn the wiring harness or even cause a vehicle fire, so technicians need to have basic knowledge of circuits and a rigorous attitude. Whether the original car or the installed lamps are to provide drivers with a better driving view and improve safety, we also call on everyone to use lights rationally and not to abuse high beams or install spotlights.
