Specifications
The HD40112Y 4″ Rectangular Amber Clearance Marker Light from Heavy Duty Lighting combines compact design with durable construction for superior roadside visibility. Measuring 3.74″ (W) × 1.22″ (H) × 0.83″ (D), it features 12 high-efficiency 5 mm amber LEDs that consume just 150 mA at 7.5–14 VDC. Encased in a fully sealed, epoxy-sealed polycarbonate lens and housing, the light resists moisture, UV, and impact. Note that this lamp requires a compatible mounting base—either HD40113PC (chrome ABS) or HD40113BP (black ABS), sold separately—for proper installation. With DOT P2 compliance and its rugged build, the HD40112Y is an ideal choice for replacing or upgrading marker lights on trailers, trucks, and commercial vehicles, combining reliability, visibility, and ease of installation.
