How to connect the lights of a car
In recent years, with the rise of automobile modification culture, more and more car owners have chosen to personalize their vehicles, among which light modification is one of the most common projects. However, changing the light is not just about replacing the light bulb. The correct wiring method is directly related to the use effect of the light and driving safety. This article will introduce in detail the wiring method of automobile light modification, and attach relevant data for reference.
1. Basic principles of automobile light modification
The automotive lighting system is mainly composed of power supply, switches, fuses, relays and lamps. When changing the lights, you need to understand the voltage, current and power matching of the original vehicle circuit to avoid overloading or short circuit of the circuit due to improper wiring.
| Lighting type | Voltage (V) | Power (W) | Wiring method |
|---|---|---|---|
| Halogen lamp | 12 | 55 | Replace the original light bulb directly |
| LED lights | 12 | 10-30 | Decoder or resistor required |
| Xenon lamp | 12 (requires boost) | 35 | A stabilizer needs to be installed |
2. Wiring steps for car light modification
1.Preparation: Turn off the vehicle power, unplug the keys to ensure safety. Prepare the tools needed to change the light, such as electrical tape, wire stripper, multimeter, etc.
2.Disassemble the original light: According to the vehicle instructions, find the installation location of the original headlights and carefully remove the lamp cover and the original headlight bulb.
3.Wiring operation: Select the corresponding wiring method according to the type of modified lamps. The following are common wiring methods for modified lamps:
| Modification type | Wiring method | Things to note |
|---|---|---|
| LED lights | The positive electrode connects to the positive electrode of the original car, and the negative electrode connects to the negative electrode of the original car | Decoder is required to avoid strobe |
| Xenon lamp | Positive and negative electrodes are connected to stabilizer, and the output of the stabilizer is connected to the lamp | Make sure the stabilizer is secure |
| Daytime running lights | Connect ACC power supply or headlight switch | Avoid battery loss due to regular electricity |
4.Test the lighting: After wiring is completed, turn on the vehicle power and test whether the light is working normally. Check for any problems such as flickering, insufficient brightness or line heating.
5.Fixed line: Use cable ties or tape to fix the line to avoid loosening or short circuit caused by vibration.
3. Frequently Asked Questions and Solutions
1.The lights are not lit: Check whether the wiring is correct, whether the fuse is blown, and whether the lamp is damaged.
2.Lights flash: It may be that the voltage is unstable or the decoder is not installed. It is recommended to install the decoder or replace the better quality power module.
3.Line heating: Check whether the line is overloaded and ensure that the wire used can withstand the power of modified lamps.
4. Safety Tips
1. Be sure to disconnect the vehicle's power when changing the light to avoid electric shock or short circuit.
2. Choose modified lamps that meet national standards to avoid failing the annual inspection due to excessive light or unqualified color temperature.
3. If you are not familiar with circuit operation, it is recommended to seek help from a professional modification shop to avoid safety hazards caused by improper wiring.
Through the above steps, you can successfully complete the wiring of the car light modification work. Remember, safety is always the first priority, and reasonable modifications can make your car both beautiful and practical.
