Can You Put LED Lights Under Your Car?

Yes, you can put LED lights under your car. Underglow lights are a fun and stylish way to transform your car into a standout. They add a little extra flair to your ride and light up the night to your vibe.

However, before you run out and start slapping some lights on your undercarriage, it’s important to research your area’s laws and ensure you comply with them. 

You also want to ensure your under-car lights installation is done properly and safely. Any electrical modification can cause damage to your vehicle if not installed correctly.

Are Underglow Lights for Cars Legal?

Installing underglow lights on your car is not legal in every state. Underglow laws vary by state or even by the municipality, so it’s important to do your research and make sure you’re not breaking any rules.

As a general rule, underglow lights for cars are legal as long as they remain covered and unlit while driving on public roads. You can install them on your car, but your lights shouldn’t be turned on or flash while driving down the highway.

Moreover, it’s generally forbidden to put car lights in red, green, or blue colors. You need to stick to the more exotic colors, such as purple or yellow. Unless you counterfeit these rules, you’re good to go on your ride and show those dazzling lights off to your heart’s content.

How Do You Install LED Glow Underbody Lights?

Installing LED strip lights under a car can be a fun and creative project to customize your vehicles. Broken down into simple steps, here’s the general installation guide you need to install LED underglow easily:

Step 1: Plan The Installation

Determine where to place the LED lights on your car and how you want to power them. You may need to measure the area where you plan to install the lights to determine the LED strip length required.

Step 2: Gather The Necessary Materials

First, you’ll need to collect the necessary materials. Below is a discreet list of the tools you might need for a successful installation:

  • Car underglow kit / Car LED Strip Lights
  • Protective gloves
  • Safety glasses
  • Zip ties
  • Electrical tape
  • Fuse Tape
  • Repair manuals

Step 3: Prepare The Car

Clean the area where you plan to mount the LED strips or under the car LED underbody light kit. Use rubbing alcohol to remove grease or dirt, and allow the area to dry completely.

Step 4: Set The Underglow Light in Place

Set the LED strip lights underside of your car and seal them in place with double-sided electrical tape. This temporary fix keeps the light strip from misplacing while you mount it permanently. 

Step 5: Mount The LED Strips

Look for the best way to securely attach the underglow installation, including bolts, brackets, or other small openings. Attach the LED strips underneath the car using the zip ties. This step ensures that the light strips are evenly spaced, securely fastened, and tucked away neatly and out of sight.

Solidify the foundation for your under-car LED strip lights with zip-ties every 10 to 12 inches. This strong fix will ensure the light strip doesn’t fall off as quickly as your car goes zooooom!

Step 6: Connect The Wire to The Power Source

Now it’s time for the technical part. 

Run wires from the under-car LED lighting to the power source and connect them using wire connectors. Route the lighting wires from under the car and into the engine bay. Secure the module box in the engine bay and connect the wires. 

Once done with the wiring process, connect the module power wire to the battery’s positive terminal and the ground wires to a clean, rust-free chassis ground contact point. 

Step 7: Place The Module Box

Place the module box in a convenient location — away from the engine or radiator and close to the engine. 

Your dashboard or center console might be the perfect place that is without the risk of heat damage as well as cool, dry, and clean. Also, extend the antenna on the module box for better reception.

Step 8: Install a Lighting Switch

If your lighting kit doesn’t support a wireless module, you need to mount a switch for the lights to function. Drill a hole to place the switch in an easily accessible location. 

Step 9: Connect The Switch To The Power Source

To connect the switch to power, you need to run the LED wires into the passenger compartment of your car. 

Find a grommet in the firewall, puncture a hole in it, and use this passageway to route the wires. Once done, connect the switch to the power source with the help of a fuse tape and connect your LED kit wiring to the chassis ground.

Step 10: Double-check for Safety 

Make sure that the wiring is done correctly. Only the right terminals should be connected. Similarly, recheck if the module box is placed in a suitable place, not where it could become damaged or caught on anything while driving.

Step 11: Test The Installation

Turn on the power source and check if the LED lights work properly. With everything installed and checked, you can now flex your new LED lights and enjoy the added visual appeal underglow brings to your car. 

It’s important to note that installation steps may vary depending on the specific LED strip lights and car model. If you’re unsure about any part of the installation process, it’s best to consult with a professional or seek out online tutorials for your specific car and LED strip lights.
