TOP-MAX LED Round Side Marker Grille Lights User Manual

1. Product Overview

The TOP-MAX LED Round Side Marker Grille Lights are designed to enhance visibility and safety for a wide range of vehicles. Made from durable rubber and PC material with a waterproof design, these lights feature bright LED lamp beads in amber and red colors. They are suitable for both marine and automotive applications.

2. Safety & Warnings

▲ Warning: Before installing or replacing the side lights, the vehicle's power switch must be turned off, the engine must be turned off, and if necessary, the negative terminal of the battery must be disconnected to prevent circuit short circuits and leakage, and to avoid electric shock or damage to the vehicle's electrical system.

3. Installation Guide

3.1 Pre-Installation Test

Before permanent installation, connect the wiring harness and test all functions (e.g., daytime running, steering, reverse) to ensure the lights are functioning properly.

3.2 Positioning and Mounting

1. Clean the intended installation surface thoroughly.
2. Determine the precise paste position (e.g., top of the wheel arch, fender, grille).
3. Mark the position with a marker pen.
4. Heat the backing adhesive on the lights to ensure a strong bond.
5. Firmly paste the lights into the marked positions.

3.3 Wiring Instructions

Careful wiring is essential for proper function and safety. Refer to the diagram below for visual guidance.

1. Hide the wiring harness along existing gaps in the vehicle body (e.g., inner side of wheel arches, side skirts, door rubber strips). Secure with zip ties.
2. If passing wires through body sheet metal holes, install a wire passing rubber sleeve to prevent abrasion of the wire insulation.
3. Power Supply: Connect the red wire to the ACC power supply (e.g., cigarette lighter fuse).
4. Ground: Connect the black wire to the vehicle's body metal (ground).
5. Turn Signal: Connect the yellow wire (or other color, if applicable) in parallel to the left/right turn signal wire using a non-breaking clip. A 1-3A fuse must be connected in series in the middle of this connection.
6. Reverse Signal: Connect the white line in parallel to the reverse light signal line. A fuse must also be connected in series for this connection.
7. Insulation and Fixing: All wiring points must be wrapped with heat shrink tubing or velvet tape for insulation. Fix the wiring harness securely to the original vehicle wiring harness with zip ties to prevent loosening.

3.4 Post-Installation Testing

After completing the installation, retest all functions of the lights to ensure they are operating correctly and check for any electrical leakage.

4. Operating Instructions

These LED lights are designed to operate automatically with your vehicle's electrical system once correctly installed. They will illuminate when the corresponding vehicle function (e.g., daytime running lights, turn signals, reverse lights) is activated.

• Daytime Running/Marker Lights: Lights will activate when the vehicle's ignition or main lighting system is on, depending on how the red wire is connected to the ACC power supply.
• Turn Signals: Amber lights will flash when the vehicle's turn signal is engaged.
• Reverse Lights: Red lights will illuminate when the vehicle is put into reverse.

5. Maintenance

The LED Round Side Marker Grille Lights require minimal maintenance to ensure long-lasting performance.

• Cleaning: Periodically clean the light covers with a soft cloth and mild soap solution to remove dirt and debris that may obstruct light output. Avoid abrasive cleaners.
• Inspection: Regularly inspect the wiring connections for any signs of wear, corrosion, or loosening. Ensure all insulation remains intact.
• Functionality Check: Occasionally test all light functions (amber, red, flashing) to confirm they are operating correctly.

6. Troubleshooting

6.1 Light Not Illuminating

• Check Power Connection: Ensure the red wire is securely connected to a constant 12V-24V DC power source (ACC).
• Check Ground Connection: Verify the black wire has a solid connection to the vehicle's chassis ground.
• Inspect Fuses: Check all inline fuses (1-3A) connected to the turn signal and reverse light wires. Replace if blown.
• Wiring Integrity: Examine the entire wiring harness for any cuts, pinches, or loose connections.

6.2 Intermittent Operation

• Loose Connections: Re-check all wiring connections for tightness.
• Corrosion: Clean any corroded terminals or connectors.
• Voltage Fluctuation: Ensure the vehicle's electrical system is providing stable 12V-24V DC power.

8. User Tips

• For optimal visibility, consider the placement of amber lights towards the front/sides and red lights towards the rear/sides of your vehicle or boat.
• When installing on a boat, ensure all connections are sealed with marine-grade sealant in addition to heat shrink tubing for maximum water resistance.
• Always double-check local regulations regarding vehicle lighting before permanent installation.
• If installing on a vehicle with complex wiring, it is advisable to consult a professional auto electrician.
