• Relay (for high-power lights)
• Switch (rocker, toggle, or dash-mount)
• Multimeter (for testing circuits)

Step-by-Step Installation:

1. Plan Your Placement:

   • Measure Twice, Cut Once: Crucial for flush mounts. Determine the exact location.
   • Check for Obstructions: Before drilling, ensure there’s nothing behind the panel (wires, structural components, fuel lines, etc.) that could be damaged.
   • Consider Beam Pattern: Aim flood lights for optimal spread, spot lights for target illumination.
   • Wiring Path: Plan how the wiring will run from the light to the power source and switch, ensuring it avoids hot or moving parts.

2. Create a Template: Most flush mount lights come with a paper template. If not, carefully trace the light’s housing (the part that goes into the hole) onto cardboard or thick paper. Cut out the template.

3. Mark and Drill Pilot Holes:

   • Tape your template securely to the desired mounting location.
   • Using a small pilot drill bit, carefully drill pilot holes at the marked corners of the template.

4. Cut the Opening:

   • Using a hole saw or a jigsaw (with a fine-tooth metal blade) following the pilot holes, carefully cut out the opening for the light. Go slowly and steadily to ensure a clean cut.
   • Pro Tip: For a cleaner cut and to prevent rust, consider painting the bare metal edges after cutting with a rust-inhibiting primer.

5. Test Fit the Light: Insert the light into the freshly cut opening to ensure it fits snugly. Make any minor adjustments if necessary.

6. Seal the Opening: Apply a generous bead of marine-grade silicone sealant around the edge of the opening before inserting the light. This is crucial for preventing water intrusion and potential rust.

7. Mount the Light: Secure the light using the provided hardware (screws, nuts, bolts). Ensure it’s tight and flush with the surface.

8. Wiring:

   • Power Source: Determine your power source (e.g., directly from the battery via a fused relay, or tapping into an existing circuit like reverse lights for auxiliary reverse lights).
   • Relay (Recommended for High Wattage): For lights over 10-15 amps, a relay is essential to protect your truck’s electrical system and ensure consistent power. Connect the light’s positive wire to the relay, and the relay to the battery (via an in-line fuse).
   • Switch: Run a wire from the relay’s trigger terminal to your chosen switch inside the cab.
   • Ground: Connect the light’s negative wire to a good chassis ground point (clean, bare metal).
   • Connections: Use high-quality crimp connectors and heat shrink tubing to protect all connections from moisture and corrosion.
   • Route Wires Safely: Secure all wiring away from sharp edges, hot components, and moving parts using cable ties.

9. Test the Lights: Before buttoning everything up, connect the battery and test the lights to ensure they function correctly.
