4. Installation Guide

4.1. Pre-Installation Check

• Ensure the vehicle's ignition is off and the battery is disconnected before beginning installation.
• Verify that the LEDUR headlights are compatible with your vehicle's existing 4x6 inch sealed beam system.

4.2. Installation Steps

1. Remove Existing Headlight:

   Carefully remove the panel screws, open the mask, and then remove the original headlight unit from its housing.

2. Connect Wiring:

   The LEDUR headlights feature a standard H4 plug for direct connection. In some vehicles, the pin configuration on the headlamp may differ. Refer to the wiring diagrams below for potential pin swapping if necessary.

4. Reconnect Battery:

   Once the headlights are securely installed and wired, reconnect the vehicle's battery.

5. Test Functionality:

   Turn on the vehicle's lights to test both high and low beam functions. Adjust alignment if necessary.

5. Operating Instructions

The LEDUR 4x6 LED Headlights operate similarly to standard vehicle headlights, providing both high and low beam functions.

• Low Beam: Provides a focused light pattern for general driving, minimizing glare for oncoming traffic.
• High Beam: Offers maximum illumination for enhanced visibility on dark roads or in areas without street lighting.

This image visually compares the light output of the LEDUR headlight in both high beam and low beam modes, showing the increased number of active LED chips for high beam.

6. Maintenance

6.1. Moisture Removal

If moisture or water accumulates inside the 4x6 LED headlights, follow these steps to remove it:

1. Step 1: Remove the breathing cap from the headlight. Store it safely.
2. Step 2: Remove the hole paper (if present) and keep it.
3. Step 3: Turn on the lamp for 30 minutes to 1 hour. This will allow the moisture to dissipate.
4. Step 4: Once all moisture is released, replace the breathing cap and hole paper securely.
