Wiring method for interior ambient lighting: Connect the positive and negative terminals to the vehicle's lighting circuit, insulate the connected wiring harness, and place it inside the original lamp cover. Note: Some models, such as fog lights, may require bumper removal. Functions of ambient lighting include: 1. Enhancing nighttime driving safety; 2. Alleviating driver fatigue and promoting relaxation; 3. Adding a sense of ritual to in-car life, creating a light and pleasant atmosphere. Ambient lighting, also known as LED ambient lighting, simulates home lighting, transforming the car into a true second living room. It complements the interior decor, with well-designed ambient lighting making the interior appear more three-dimensional.

Last time I installed ambient lighting myself, I found the process quite simple, mainly about choosing the right location and preparing the tools. First, you need LED light strips and a wiring kit, usually with positive and negative wires. I bought mine online for just a few dozen yuan. For wiring, the key is to find a power source, such as the car's cigarette lighter socket—just plug it in and it lights up. But for a cleaner look, you'll need to connect to the fuse box. The fuse box is usually located under the steering wheel. Open it, find the ACC fuse, and use a fuse tap to connect the positive wire. The negative wire should be connected to a metal part of the car body as the ground, ensuring it's tightened to avoid loosening. Always remember to disconnect the negative battery terminal to prevent short circuits. Tools needed include wire strippers, tape, and a multimeter to test if the voltage is 12V. After installation, check if the lighting is even. I recommend placing the lights in door gaps or under the dashboard—both discreet and effective. Regularly maintain the wires and connectors to avoid aging issues, ensuring the ambient lighting lasts long and instantly enhances the driving atmosphere at night.

Installing ambient lighting requires careful planning, starting with safety. I always begin by turning off the engine and disconnecting the negative battery terminal to reduce the risk of electric shock. Find a suitable power cable, connect the positive wire to the ACC port in the fuse box—this ensures power only when the ignition is on, saving energy and enhancing safety. Secure the negative wire with an alligator clip to the metal frame of the car for stability. I also add a fuse to the positive line to prevent overload, typically a 5A fuse is sufficient. For tools, use a wire stripper to expose the wire ends and connect them with quick connectors or solder to avoid loose connections. Choose locations like the dashboard or footwell area, and use cable clips to organize the wiring neatly to avoid interference while driving. Test with a multimeter to check connectivity, and once the lights work properly, secure the light strips. Regularly clean dust and check for loose connections to extend lifespan and prevent potential fire hazards. If it seems too complicated, purchasing a kit with a controller makes it easier to adjust color temperature.

To wire ambient lights, first try simple methods like the cigarette lighter socket. Many lights now come with USB plugs, allowing direct connection via a cigarette lighter adapter without wiring. However, if you want a permanent installation, you'll need to access the power source. Key steps include disconnecting the battery, connecting the positive wire to the ACC fuse in the fuse box, and grounding the negative wire to a seat screw. Before starting, check the wire material and use heat-resistant ones to prevent melting. Choose a suitable location, such as door handles or the ceiling, and conceal the wiring with tape. After installation, test the lights to ensure no abnormal sounds. Safety first—if unsure, consult a professional to avoid accidents.

The core of installing ambient lighting lies in managing the current path. By studying the circuit diagram, I learned that a stable 12V DC power supply is essential. The positive terminal draws power from the ACC position in the fuse box, with an appropriate fuse for circuit protection; the negative terminal must be securely grounded, fastened with screws to an unpainted chassis point. Use wire strippers to remove insulation, seal connection points with heat shrink tubing for moisture resistance, and connect the signal wire to the controller to adjust brightness and color. Measure voltage with a multimeter, keeping it within 12V to prevent bulb damage. Recommended tools include insulated pliers and wiring terminals, with all operations performed power-off to avoid sparks. Pay attention to heat dissipation during installation—areas under the dashboard with good ventilation are ideal, and secure wiring harnesses with cable ties to minimize vibration wear. After each startup, check light functionality and troubleshoot any issues promptly.
