Work lamps and filters may seem like “small components,” but they directly affect nighttime construction safety, engine life, and hydraulic system reliability. In the construction machinery aftermarket, the selection of electrical and filtration parts also requires attention.

Work lamps are used for nighttime, tunnel, port, and mining lighting. On the LIANYU Global product page, the 803502426 and XGGD03 Working Lamp are suitable for the wheel loader LW300F and LW300KN. When choosing work lamps, pay attention to voltage, power, protection grade, vibration resistance, and waterproof and dustproof performance. LED work lamps offer high brightness and low energy consumption, but heat dissipation and electromagnetic compatibility must be considered. Halogen lamps have low cost but generate more heat. Common faults include failure to light, flickering, and water mist inside the lamp, usually related to oxidized plugs, fuses, relays, or poor grounding.

Filters include air filters, oil filters, fuel filters, and hydraulic filters. A blocked air filter can cause insufficient engine intake air, black smoke, and reduced power. A blocked fuel filter can cause difficult starting. A blocked hydraulic filter can cause slow movement and high oil temperature. During maintenance, shorten the replacement interval according to working conditions, check sealing rings during installation, and avoid using inferior filter elements. The LIANYU Global product page also includes diesel engine parts, electrical parts, filters, and hydraulic systems, indicating that construction machinery parts need systematic matching rather than focusing on a single part.
