Installing car LED strip lights is a straightforward DIY project that enhances your vehicle's interior ambiance. The core process involves planning the layout, connecting the strips to a power source (typically the 12V battery or fuse box), and securely mounting them. Always disconnect the negative battery terminal before starting any electrical work for safety. The most critical step is identifying a proper switched power source, like the fuse for the cigarette lighter or radio, so the lights turn on and off with the car. For a clean, professional look, focus on hiding wires and using the included adhesive or additional clips for a secure fit.
You'll need a few basic tools: the LED light strips, a wiring harness (often included in kits), a fuse tap, wire connectors, and basic tools like a trim removal tool and wire strippers. Most quality kits are plug-and-play, simplifying the process.
Step-by-Step Installation Guide:
-
Plan the Layout: Test-fit the LED strips without peeling the adhesive backing. Ideal locations include under the dashboard, along the footwells, or on the back of seats. Ensure the strips won't interfere with pedals, airbags, or moving parts.
-
Access the Fuse Box: The vehicle's fuse box is usually located in the driver's side footwell or under the hood. Consult your owner's manual for its exact location and the diagram identifying each fuse's function.
-
Find a Switched Power Source: Use a fuse tap to connect the LED harness's red (positive) wire to a fuse that only has power when the ignition is on. The cigarette lighter (also called a 12V accessory socket) or radio fuse are common and safe choices. This prevents the lights from draining your battery.
| Common Fuse Box Locations & Suggested Circuits for LED Lights | |
|---|
| Location | Suggested Switched Circuit |
| Interior (Driver's Side Kick Panel) | Cigarette Lighter / 12V Power Outlet |
| Interior (Passenger Side) | Radio / Infotainment System |
| Under-Hood | Not typically recommended for interior lights |
-
Connect the Ground Wire: The black wire from the harness must be connected to a clean, unpainted metal bolt or screw that connects directly to the vehicle's chassis. This completes the circuit.
-
Mount the Lights and Manage Wires: Peel the adhesive backing and firmly press the strips into your planned locations. Use cable ties or adhesive clips to neatly tuck wires away, preventing rattles and ensuring a tidy finish.
-
Test and Reassemble: Reconnect the battery and test the lights. If they work correctly, carefully reinstall any trim panels you removed. If they don't light up, double-check all connections, especially the ground.
For a truly custom effect, many LED kits come with a remote or smartphone app for color changing. If you're not comfortable with wiring, having a professional install them is a worthwhile investment to avoid potential electrical issues.
