Underbody Light Kit

 Shop Underbody Light Kit

Installing an underbody light kit is one way of adding a personal touch to your ride. Available in various colors, you can easily choose one that'll complement your car's overall look. Plus, attaching this kit into your vehicle is easy as long as you have the right tools. Here's how to install underbody lights:

Tools you'll need:

  • Heat shrink tubing
  • Drill and bit
  • Wire cutters
  • Metal punch
  • Silicone-based sealant
  • Soldering iron

Step 1: Disconnect your car's battery.

Before starting with any car installation, make sure the battery is disconnected to avoid accidents.

Step 2: Attach the retaining clips to each underbody light.

Install the retaining clips into each light. Position the lights with clips on the underside of the vehicle, making sure that the spots you choose are away from fuel lines, electrical wires, and moving parts. Mark the spots using a pencil; these will serve as guides when drilling the screw holes.

Step 3: Drill the holes.

Using a metal punch, dent the spots marked with a pencil. Then drill the holes using a drill and bit. When drilling the holes, the size should be a bit smaller than the retaining clips to ensure a tight and secure fit.

Step 4: Install the underbody lights.

Before attaching the lights, put some silicone-based sealant on the holes for a watertight seal. Using the screws included in the underbody light kit, attach each light with retaining clips into the holes. Repeat the process until all lights are screwed in place.

Step 5: Attach the transformer.

Install the transformer that's included in the underbody light kit under the hood. The perfect location for the transformer is somewhere near the battery. But make sure the transformer won't get exposed to heat, moisture, and moving parts.

Step 6: Route the wires from the lights to the transformer and the battery.

Connect the wires from each light into the transformer. Then route the same wires to the battery. Attach the wires through your car's firewall and along the interior dash's underside. Look for an existing firewall wiring loom so you won't have to drill a hole. Cover the power wire with a heat shrink tubing to protect it from heat.

Step 7: Solder the wires together.

Solder the power wire and the inline fuse wire that's found near the battery. After soldering, dab the soldered joint with a bit of sealant. Then shrink the tubing with a heat gun or lighter.

Step 8: Route a wire to the switch terminals.

Connect another power wire from the transformer's positive terminal to the same location of the other power wire. Then solder both the power wires to the wires for the toggle switch. This way, you'll be able to control the lights within the comforts of the driver's seat.

Step 9: Reconnect the battery and test the lights.

After lining the negative wire to a ground wire, reattach the battery cables and switch on the engine to see if all the parts of the underbody light kit are working properly. For your convenience, you can mount the light switch beneath the dashboard.
