How to wire 12v led strip lights in car

Here is a quick guide on how to wire 12v LED strip lights in car. I have used thin flexible LED strips and tested the best possible ways to install them. You might not notice the difference while driving, but installing LEDs uses less power which saves gas and money, so let’s dive right in.

12v led strip lighting is rapidly becoming one of the most popular methods for using light in vehicles. It’s durable, has a wide range of power usage, and is also fully waterproof. It’s easy to install and easy to hide or show (bright or dimmed). The only issue that you may worry about when deciding to use this kind of light is how to wire 12v led strip lights in the car. Well, there is no need to worry anymore because I will explain the process in just a moment.

How to wire 12v led strip lights in car?

It is easy to do. Just get the power from a battery or directly from the car’s electrical system. I would recommend getting the car battery power because that is the most reliable power source. You can do it in the following ways

  • (1) Check the car manual to find out where the battery is. Then, take off the black plastic cover(if there is) right next to it. Next, remove the terminal end cap, and find the pigtail with wires coming out. This is the wire that you’re going to tap into. The wire color doesn’t matter.
  • (2) Get a wiretap connector, and connect it to the pigtail wire. Then, get a wire (any color) from the main battery terminal, and connect the wiretap connector to it, and you’re done.
  • (3) If you want to wire it permanently to the car, you can get a wiretap connector and a wire, cut off the connector, and solder them together. Then, go to the terminal and cap that you unloaded earlier, and open it. Put the wire into the hole and tighten it, and you’re done. Enjoy!

The best way to wire the lights is by using a relay. A relay will help you control the lights with the same switch used to turn your engine on and off. Connect a 12-volt power source to the relay by running a wire from the rear of the vehicle, up to the headlight. Use a fuse to protect the power wires from a short circuit. Next, connect each of the three lights (or more, depending on what you want) to the relay.

For instance, the red light will be connected to the “load” terminal of the relay. Towards the “source” of the relay, you will run another wire to the headlight and connect it to the positive terminal. When the relay receives a 12-volt signal, it will activate and send power to the red led strip light. Connect the black wire to the ground.

High-quality LED lights are more efficient with a 100,000-hour life and low power consumption. LED strip lights are suitable for outdoor and indoor lighting, such as in-car, cabinets, on the cove, and so on. The way to wire 12v LED strip lights in a car is quite simple, you can use a wire stripper to remove the external insulation of the wires and expose about an inch of wire. Then strip about an inch off of the other end of the wire so that you have about three inches of wire exposed. Next, use the wire stripper again to expose the wires and then twist the exposed wires together. Do the same thing to the other end of the wire.

How do you connect 12V LED strip lights to a car battery?

There are many ways to connect the LEDs to a car battery, you should use the wires and connectors to install. You can buy these accessories from an electronics store near you or on the internet. You can simply splice the wires into the negative and positive terminals on the battery. The problem with this method is that the splices on your wires could corrode and cause a short. It’s a good idea to use heat shrink tubing on the spliced wires to provide extra protection from shorts. You can also use a power distributor to make the installation easier.

How do you power a 12v LED strip?

A 12V power supply can be used to power a 12v LED strip. The 12V power supply can be either plugged into the wall outlet or a 12V battery can be used for this purpose. The 12v LED strip can be easily connected to the power supply with the help of an adapter.

Do 12v led strips need resistors?

Of course, you will have a resistor for a 12v led strip. The reason is simple, the resistors will protect your led strip and make it work longer. Well, actually you have no other option than to use the right resistor. If you are using a non-correct resistor, the led strip won’t be bright and they will get hot quickly. If you use a too low value of the resistor, your strip may not light up at all. That’s why you must use the right resistor in your 12v led strip.

Can you power a 12V LED strip with batteries?

You can use a 12V battery charger to power the LED light strip. The battery charger is a small device used to charge the car battery. A car battery charger has different outputs ranging from 6V to 24V depending on the car model and the make of the charger. You can get a 12V charger if your car is of a higher make. The charger has a wire that needs to be connected to any of the car’s terminals in order for it to start charging the battery.

Can I power a 12V LED strip with a USB?

Yes. A single USB can power a very weak LED strip. Many of the USB ports found on computers are capable of supplying a high current to power an LED strip. This high current is needed to power LEDs. Connect the red wire of the USB to the positive of the battery and the negative of the battery to the negative of the LED strip.

What is the proper transformer for 12V LED strips?

Your 12v LED Strip is 12V but your transformer is 110 – 240V. This means that your transformer has to be able to handle both of these voltages. The transformer will have an input voltage and an output voltage. Some of the lower-quality transformers have a single voltage output. These will not work. You will want to make sure you have a power supply that does indeed change the voltage.  The output should be 12V.

What is the difference between 12V and 24V LED lights?

12V lights consume half the power compared to the 24V lights. The brightness of 24V lights is much greater than the 12V lights. 24V lights are used for high-intensity work like street lights and 12V lights are used for indoor illumination.

To begin with, power is measured in watts. Power = voltage x current, so the higher the voltage, the less current is needed to achieve a given power. This is why you can use a 12V car battery to power a 12V light-emitting diode (LED) and a 24V car battery to power a 24V LED. Also, a higher voltage can mean less power consumption for the same amount of light emitted. So, a 12-volt light-emitting diode that’s rated to deliver one watt of power will draw more current at 12 volts than it will at 24 volts. And that is why 12V LEDs are cheaper than 24V ones of the same wattage.

Are all LED strips 12V?

Not all LED strips are 12 volts. In fact, most LED strips are 24V. The reason why I say that most of the LED strips are 24V is that most of the strips that I have used at home are 24 volts. The red and black leads of the LED strip should be connected to the positive and negative terminals of the power source respectively. If you are planning to use a 12V adapter, then the red and black leads should be connected in series to the power supply.
