How To Install Electric For Subaru Bumper Flood Lights

How to Install Electric Wiring for Subaru Bumper Flood Lights

Adding flood lights to your Subaru's bumper can significantly improve visibility and safety, especially during nighttime driving or off-road adventures. This guide will walk you through the process of installing the electrical wiring for these lights, focusing on a safe and effective approach. Remember to always disconnect your battery's negative terminal before starting any electrical work. This is crucial for your safety.

Planning Your Installation

Before you begin, you need to plan your installation carefully. This includes:

1. Choosing Your Lights and Switch:

• Light Type: Select flood lights appropriate for your Subaru's bumper. Consider their size, brightness (lumens), and mounting style. Ensure they're designed for automotive use and are weatherproof.
• Switch Location: Decide where you want to place the switch for your flood lights. Common locations include near the headlight switch, on the center console, or even integrated into an existing switch panel.
• Wiring Gauge: Select appropriate gauge wiring based on the amperage draw of your lights. Thicker gauge wire (lower number, e.g., 10 AWG) is better for higher amperage and longer runs to minimize voltage drop. A qualified auto electrician can help determine the right gauge for your specific setup.

2. Gathering Your Materials:

• Flood Lights: The lights themselves.
• Wiring Harness: This will include the necessary wires, connectors, and a relay (highly recommended).
• Switch: A toggle switch or rocker switch, appropriately rated for the amperage of your lights.
• Relay: A relay protects your vehicle's electrical system and prevents overheating.
• Fuse: A fuse protects your wiring from overcurrent.
• Wire Connectors: Crimp connectors or solder and heat shrink tubing for secure connections.
• Zip Ties/Cable Ties: To secure the wiring neatly.
• Drill and Drill Bits (if needed): For drilling holes in the bumper for mounting the lights.
• Electrical Tape: For extra insulation.
• Measuring Tape: To measure wire lengths.
• Wire Strippers/Cutters: To prepare the wires for connection.

Installing the Wiring

This section describes the general steps; specifics may vary depending on your Subaru model and chosen lighting system. Consult your Subaru's wiring diagram if possible.

1. Running the Wires:

• From the Lights: Carefully route the wires from your flood lights through the bumper and into the vehicle's interior. Try to use existing pathways or protective coverings to prevent damage to the wires.
• To the Battery (or Fuse Box): Run the power wire (positive wire) directly to the battery (or a suitable fused source). Using a fuse box is highly recommended for safety. Ground the negative wire to a suitable ground point on the chassis, making sure it has a good metal-to-metal contact. Avoid running wires near moving parts or sharp edges.

2. Connecting the Relay:

• Wiring the Relay: Properly connect the relay according to its wiring diagram. The relay acts as a switch, allowing the lights to be controlled by the lower current switch in the cabin, protecting your vehicle's wiring.
• Power Source: Connect the relay's power input to the battery (or fused source).
• Switch Trigger: Connect the switch to the relay's coil.
• Light Output: Connect the relay's output to the flood lights.
• Ground: Ensure the relay is properly grounded.

3. Connecting the Switch:

• Wiring the Switch: Connect the switch to the relay's coil. The switch will turn the relay on and off, controlling the flood lights.
• Grounding the Switch: Ensure the switch is properly grounded.

4. Securing the Wiring:

• Use zip ties or cable ties to neatly secure the wiring along its route. This prevents the wires from becoming damaged or tangled.

5. Testing and Finishing:

• Test the Lights: Reconnect the battery's negative terminal and test the flood lights. Ensure they turn on and off correctly.
• Fuse Check: Check that the fuse is working correctly and hasn't blown.
• Final Touches: Tuck away any excess wiring neatly.

Important Safety Considerations:

• Professional Help: If you are not comfortable working with automotive electrical systems, it's always best to consult a professional auto electrician.
• Proper Grounding: A poor ground can cause intermittent operation or damage to the electrical system.
• Fuse Protection: Always use an appropriately rated fuse to protect your wiring.
• Weatherproofing: Ensure all connections are weatherproofed to prevent corrosion and short circuits.

By following these steps and prioritizing safety, you can successfully install electric wiring for your Subaru bumper flood lights, enhancing both safety and functionality. Remember to double-check all connections before operating the lights. Enjoy the improved visibility!
