Headlight, front leftright 803587851

Product Introduction

This 803587851 front headlight set includes left and right combination headlights, designed as a complete lighting assembly for wheel loaders. It integrates high beam, low beam and turn signal functions to deliver sufficient illumination for night operation and signal warning on construction sites. The matched wiring harness and dedicated plugs enable direct plug-and-play installation without extra wiring modification.

The lamp housing adopts high-strength ABS material with good impact resistance. The transparent lens is made of high-transmittance polycarbonate, resisting scratches, UV aging and yellowing under outdoor exposure. Internal sealing structure provides reliable waterproof and dustproof performance, adapting to muddy, dusty and wet working environments. Precisely matched mounting bases and reserved bolt holes align perfectly with the original equipment position. The pre-assembled wiring harness with waterproof connectors ensures stable power supply and reduces short-circuit risks during heavy vibration.

Manufactured strictly in accordance with OEM dimensional standards, this headlight assembly can directly replace original spare parts without modification. We supply OEM equivalent and premium aftermarket quality grades. Every finished lamp undergoes lighting test and waterproof inspection before shipment. Export-grade packaging and complete customs documents are available for overseas construction machinery repair shops and equipment distributors.
