Product Specifications

I. Product Positioning

The 24V H15 (PGJ23T-1) is an intelligent dual-filament halogen headlight specifically engineered for modern heavy commercial vehicles, featuring the unique PGJ23T-1 three-tab base with central square alignment slot. As an advanced configuration in commercial vehicle lighting systems, this bulb integrates standard low beam and integrated front fog light functions into a single unit. Optimized for 24V commercial vehicle electrical systems, it is designed to enhance driving safety and visibility in complex weather conditions.

II. Key Features

1. Innovative Dual-Function Integration

   • Intelligent Dual-Filament System: Main filament (55W) provides standard low beam illumination; auxiliary filament (15W/21W) serves as integrated fog light, independently controlled by vehicle circuitry

   • PGJ23T-1 Dedicated Base: Three-tab design with central square alignment slot ensures absolute precision in bulb positioning within the reflector

   • Space-Optimized Solution: Single bulb delivers two lighting functions, reducing number of lamp units and simplifying commercial vehicle front-end design

2. Professional Optical Performance

   • Precision Dual-Beam Output: Low-beam filament produces ECE-compliant anti-glare cutoff pattern; fog light filament delivers wide warm yellow beam for enhanced rain/fog penetration

   • Optimized Thermal Management: Independent heat dissipation design for each filament prevents mutual thermal interference, extending overall service life

   • Professional Color Matching: 4300K white light for normal illumination needs; 3000K yellow light optimizes bad weather penetration

3. Commercial Vehicle Grade Durability

   • Reinforced Vibration-Resistant Structure: Utilizes commercial vehicle specific reinforced filament supports and damping systems, suitable for continuous vibration in long-haul transport

   • Wide Voltage Stability: Maintains stable performance within 22V-28V range, tolerating diesel vehicle electrical system fluctuations

   • Environmental Sealing Design: Base interface employs multi-layer sealing technology with IP6K7 protection rating, resisting mud and water ingress

III. Vehicle Applications

• European Premium Commercial Vehicles:

  • Select intelligent lighting versions of Mercedes New Actros (post-2018)

  • High-specification Volvo FH series models with integrated fog light headlight systems

  • Scania S/R series versions with optional all-weather lighting packages

  • MAN TGX Individual Line customized configuration models

• Specialty Work Vehicles:

  • Intelligent lighting systems for fire and rescue vehicles

  • Enhanced weather-adaptive light groups for snow operation vehicles

  • All-weather forward lighting systems for long-haul refrigerated transport trucks

• Premium Bus Configurations:

  • Intelligent safety lighting packages for luxury intercity coaches

  • All-weather vision systems for airport VIP shuttle buses

  • Safety-enhanced configurations for special transport vehicles (hazardous materials, valuables)

IV. Installation & Usage Guidelines

• Precision Installation: PGJ23T-1 base square slot must align perfectly with socket alignment pin to ensure optical positioning accuracy

• Circuit Verification: Confirm vehicle circuitry supports independent dual-filament control before installation

• Function Testing: Test both low beam and fog light functions separately after installation to ensure proper operation

• Sealing Treatment: Must use OEM-specification waterproof gasket during reinstallation

V. Maintenance Recommendations

• Regularly clean bulb contact areas to prevent oxidation-related poor connections

• Inspect socket alignment mechanism to ensure optical positioning accuracy

• Dual-filament system recommended for preventive replacement per manufacturer intervals

• Avoid touching glass surface during maintenance to prevent oil contamination affecting heat dissipation
