How to Wire LED Strip Lights in a Car

When installing LED car light, the first thing you need to do is wire them. You should always leave at least 1.5" of space between the strip and the car's battery. You should also cut the LED light strips on their copper solder pads; cutting them anywhere else may result in damaged LEDs. If you need to temporarily mount the strip, you can use painter's tape or scotch tape to secure it to the vehicle's surface. Once the temporary mounting is complete, you should run the wires back to the central location. It is important to turn the vehicle off when working on the installation.


Soldering LED strip lights in a car can be a relatively straightforward DIY project. However, you should make sure to follow some important safety precautions. For starters, you should always test the lights thoroughly before you start soldering them. To do this, touch the positive and negative leads of each strip light to the corresponding posts on the 9-volt battery.

If one LED does not light up, then it may have been cut in the wrong place or may have a manufacturing defect. If this is the case, you should reheat the solder joint. If that fails, you can remove the section and rejoin it with the connector clips. If this method is not effective, you may need to ask a professional to help you with this task.

The LED system will require a power cable. This power cable must match the polarities of the strips' wires. The positive lead should be attached with a wire nut, while the negative lead should be connected with a screw terminal. You can also use a wire nut to connect the positive lead to the first screw terminal. The LEDs will then automatically turn on when the vehicle starts and stay on until it is switched off.

When you are adding LED strip light to your car, you will need to connect a fuse to the power cable. The fuse needs to be polarity-matched with the LED system. Then, you can connect the positive and negative leads of the LED strips with wire nuts. Finally, you can connect the power cable to the first screw terminal in series. The LEDs will turn on when the car turns on and remain on until you turn off the car.

When hardwiring LED strip lights in a car, you need to ensure that you have a +12V power supply. This means a cigarette lighter socket or a fuse located in the vehicle's body. Make sure the strip lights are secured properly to avoid damage. Once installed, make sure the strips are securely attached with electrical tape and zip ties. If they become loose in the future, make sure to re-secure them. Repeat this process for all of the strip lights in your car.

Once they are installed, you can then attach the wires to the battery using extension wires. The red wire should be attached to the positive terminal of the battery, and the black wire should be connected to the negative. You can also connect the ground wire to the chassis ground.
