Setup and Installation
This headlight is designed for universal fitment in vehicles requiring 4x6 inch rectangular headlights. Installation procedures may vary slightly depending on your specific vehicle model. Always refer to your vehicle's service manual for specific headlight removal and installation instructions.
- Preparation:
- Park the vehicle on a level surface and engage the parking brake.
- Turn off the engine and remove the key from the ignition.
- Disconnect the negative terminal of the vehicle's battery to prevent electrical hazards.
- Allow existing headlights to cool down if they have been recently in use.
- Remove Existing Headlight:
- Locate and remove any retaining rings, screws, or clips securing the old headlight assembly.
- Carefully pull the old headlight forward and disconnect the electrical connector from the back.
- Remove the old headlight from the vehicle.
- Install New Headlight:
- Connect the electrical connector of the United Pacific 34133 headlight to the vehicle's wiring harness. Ensure a secure and proper connection.
- Carefully position the new headlight into the headlight bucket or mounting frame.
- Secure the headlight using the original retaining rings, screws, or clips. Ensure it is firmly seated and does not wobble.
- Wiring for Heated Function (if applicable):
- The heated function typically requires a separate power connection. Consult the wiring diagram provided with your specific vehicle or a qualified technician for integrating the heated element into your vehicle's electrical system.
- Ensure the heated element is connected to a switched power source (e.g., ignition-on) and properly fused.
- Final Checks:
- Reconnect the negative terminal of the vehicle's battery.
- Turn on the vehicle's headlights and verify that both low beams are functioning correctly.
- Test the heated function if it has been wired.

This function typically activates automatically when the ambient temperature drops below a certain threshold or can be manually controlled if wired to a switch. Refer to your vehicle's specific wiring setup for details on activation.
