Setup and Installation

The Morimoto Sealed4 headlights are designed for a direct replacement of existing 4x6 inch sealed beam headlights, featuring H4 3-pin male inputs for a plug-and-play installation in most compatible vehicles.

1. Preparation: Park the vehicle on a level surface and engage the parking brake. Disconnect the negative terminal of the vehicle's battery.
2. Remove Old Headlights: Carefully remove the bezel or trim surrounding the existing 4x6 inch headlights. Disconnect the wiring harness from the back of the old headlight and remove any retaining clips or screws holding it in place. Gently pull out the old headlight unit.
3. Connect New Headlights: Connect the H4 3-pin male input of the Morimoto Sealed4 LED headlight to the vehicle's existing H4 wiring harness. Ensure the connection is secure.
4. Install New Headlights: Insert the Morimoto Sealed4 LED headlight into the headlight bucket. Secure it using the original retaining clips or screws. Ensure the headlight is seated properly and firmly.
5. Test Functionality: Reconnect the vehicle's battery. Turn on the headlights (low beam and high beam) and check for proper operation. Verify that both headlights illuminate correctly and switch between low and high beams.
6. Aiming (if necessary): If the beam pattern appears incorrect, refer to your vehicle's service manual or local regulations for proper headlight aiming procedures.
7. Final Assembly: Reinstall any bezels or trim removed earlier.

Operating Instructions

The Morimoto Sealed4 LED headlights provide distinct low and high beam functionalities for optimal road illumination.

• Low Beam: When activated, the low beam utilizes NCSW170C Series LEDs and Morimoto's Kuria Optic projector lens array to produce a precisely controlled 2400 lumen output with a Left-Hand Drive (LHD) stepped beam pattern. This pattern is designed to illuminate the road ahead without causing glare to oncoming traffic.
• High Beam: Switching to high beam mode engages additional LEDs, increasing the total light output to an impressive 4300 lumens. The high beam provides maximum illumination for improved visibility on unlit roads or when additional light is required.

Maintenance

The Morimoto Sealed4 LED headlights are designed for durability and minimal maintenance.

• Cleaning: Clean the UV-coated polycarbonate lenses with a soft cloth and mild soap and water. Avoid abrasive cleaners or harsh chemicals that could damage the lens coating.
• Inspection: Periodically inspect the headlights for any signs of damage, loose connections, or debris accumulation.
• Heat Management: The heavy-duty die-cast housings are designed to act as efficient heat sinks, ensuring optimal LED performance and longevity. No user maintenance is required for heat management.
