  • Simple plug-and-play wiring.

LED strips lend lots of creative lighting possibilities to any car, truck or SUV!

Planning Your LED Strip Light Installation

Careful planning ensures an optimized LED strip light installation:

  • Decide on interior or exterior lighting application.
  • Measure available mounting surfaces and dimensions.
  • Account for required wiring access holes into cabin.
  • Select LED strip types suitable for chosen locations.
  • Determine needed LED strip length – buy longer strips and cut to fit.
  • Use UV and weather-resistant strips for exterior uses.
  • Check vehicle manual regarding electronic modules that may need protecting during install.
  • Gather tools – trim removal tools, drill, wiring supplies, alcohol prep pads.
  • Have the vehicle present for test fitting strips.

Meticulous planning and preparation prevents headaches down the road.

Safety Tips for Installation

Exercise the following precautions when installing LED strips:

  • Disconnect the battery before wiring to avoid shocks and electrical shorts.
  • Avoid drilling or screws near control modules, gas tanks, brake lines. Check manuals.
  • Use grommets when routing wires through metal to avoid cuts and shorts.
  • Keep strips away from hot exhaust components.
  • Prevent pinching wires when reinstalling interior panels.
  • Verify all strips and components are well secured before driving.
  • Wear eye protection when drilling.
  • Take care on ladders reaching roof.

Installing LED strips requires working around live 12V systems. Caution prevents electrical hazards and damage.

Recommended LED Strip Lights for Cars

Look for LED strips with these ideal qualities:

  • Flexible – Can bend to contours and shapes of car.
  • 12V DC – Operates on car’s electrical system.
  • Waterproof – Prevents moisture damage (IP65+ rated).
  • LED density – Has at least 60 LEDs per meter for good illumination.
  • RGB color – Allows creating custom colored lighting effects.
  • Automotive grade – Rated for vehicular vibration and temperature extremes.
  • Self-adhesive – Securely sticks to car surfaces while removable.
  • Controller included – Has remote, buttons, or app control.

DO NOT use common household 12V LED strips – choose automotive- specialized products only.

Wiring and Powering LED Strip Lights

Follow these guidelines when wiring automotive LED strips:

  • Use 16 or 18 AWG automotive grade power wire for extensions.
  • Solder or properly crimp connections for reliability. AvoidWire strips using twist-on wire connectors.
  • Avoid routing wires near hot, sharp or moving components.
  • Use grommets when passing wires through metal barriers.
  • Make flexible loops in wiring to allow movement without disconnection.
  • Use cable management clips to prevent wires tugging loose.
  • Install LED controller module in protected, accessible location.
  • Connect to 12V DC power – accessories, cigarette lighter, battery.
  • Incorporate an inline fuse for electrical protection.
  • Check polarity – wire positive (+) and negative (-) correctly.

Proper wiring prevents damage, shorts, and unstable LED strip operation.

How to Install Interior Car LED Strips

Interior LED strip installation:

  1. Clean mounting surface thoroughly. Wipe with alcohol pad. Test fit LED strips.
  2. Determine wiring path to 12V power source. Run wires cleanly using clips. Insert grommets when passing through metal.
  3. Peel backing and press LED strip firmly onto surface. Apply steady pressure to adhere.
  4. Align strips neatly. Cut strips to fit with scissors on cut marks. Add wire extensions.
  5. Connect wires properly to power source and controller. Check polarity. Add fuse.
  6. Turn lights on to verify operation then reinstall interior panels. Avoid pinching wires.

With care, LED strips can accent interior footwells, door frames, dashboard, headliner, seats etc.

Installation Tips for Exterior LED Strip Lighting

Tips for installing exterior LED strips:

  • Choose LED strip lights rated IP67 or higher for waterproofing.
  • Prepare surfaces by cleaning thoroughly and lightly sanding for maximum adhesion.
  • Consider applying primer then paintable silicone where needed to match body color.
  • Avoid placing strips on hot exhaust or engine components. Heat damages LEDs.
  • Seal all connections thoroughly using quality heat shrink, waterproof connectors and silicone.
  • Route wires into the cabin interior using protected passages through the firewall. Use grommets.
  • Attach strips securely using automotive grade mounting tape or bolts where suitable.
  • Check strips for secure adhesion and routing without wire tugging periodically.

Proper surface prep and weatherproofing ensures exterior LED strips survive the elements.

How to Install LED Underbody and Ground Effects

For underbody and ground effects:

  1. Plan layout of LED strips to highlight desired areas and ensure adequate road clearance.
  2. Thoroughly clean underbody mounting surface using degreaser. Lightly scuff with sandpaper.
  3. Run wires from strips into the cabin through protected grommeted holes. Seal holes properly.
  4. Adhere LED strips using automotive grade mounting tape or fasteners if possible.
  5. Make watertight wire splices and connections using quality heat shrink. Seal terminals.
  6. Secure wires tightly using clips to prevent sagging.
  7. Check clearance again and test illumination before driving.

Take precautions to properly seal wires and terminals from road debris, water, salts, and vibration.
