LED lights are a convenient and cost-effective way to light up the interior of your car. They come in varying degrees of controllable brightness, wavelengths, and looks which offer customization options according to the user’s taste. Compared to their counterpart, incandescent light, these are smaller in size, save more energy, and are much brighter.

Why LED Lights?

Led lights for the interior can provide many benefits; they aren’t just eye candy. They are the smarter choice for both looks and usage.


Although these are more expensive than incandescent lights, they last far longer and save far more energy, making them a better option for the long term.


Some LED lights can be controlled via a remote, which makes it far more convenient than reaching for the stock light.


These come in varying styles and offer varying degrees of brightness and colors, which can be controlled by a remote. There are different sizes and shapes of LED lights; you can get LED bulbs, strips, or any appearance you might want. Whereas incandescent lights mainly offer a dull yellow interior.

Brighter Interior

LED lights are brighter than stock bulbs, so they light up all compartments of your vehicle; installing them can help you see in any part of the interior.

How to Hardwire LED Lights

The process of wiring your LED lights is relatively straightforward, requiring equipment you can find at any hardware store. The process is explained below:

Equipment and Materials:

  • 12 gauge AWG cables
  • Drill
  • Rubber Grommet
  • Safety gloves
  • In-line fuse


  • Detach the car battery before starting this process.
  • Attach a twelve-gauge (American with wire gauge/brown and Sharpe wire gauge )cable to the positive terminal of the battery.
  • Now attach the AWG cable to an in-line fuse. The fuse protects your lights from excessive voltage from your car battery, which could cause them to get damaged.
  • Locate the fuse within twenty inches of the battery but away from the engine and heated areas of the bonnet.
  • Make a cavity into the firewall using the drill and fill it with a rubber grommet which will prevent abrasion of your cables and the metal part of your vehicle. Pull the AWG cable through the hole which was just made.
  • Attach the AWG cable to the car’s control switch, and follow the manufacturer’s instructions.
  • Connect the control switch to the LED lights via twelve-gauge AWG cables.
  • Reconnect your battery, and when you ignite your engine, you should be able to activate and deactivate the lights with the control switch.

Caution: Wear safety gloves during this procedure.

Final Note

In conclusion, hardwiring LED lights isn’t as tough of a task as it may sound. The procedure is straightforward, and anyone with minimal hardware experience can handle this. This tutorial simplifies the process.
