The Shacman H3000 Rear Work Light Switch is a purpose-built dashboard control designed to give drivers instant, reliable command over the rear work lights and auxiliary lighting systems on Shacman H3000 series heavy-duty trucks. This Shacman H3000 Rear Work Light Switch genuine OEM component ensures that you can illuminate the working area behind your vehicle with the simple press of a button, enhancing safety and productivity during night-time loading, unloading, or any rear‑facing operation.
The Shacman H3000 Rear Work Light Switch is engineered with the driver in mind, featuring a large, easy-to-operate push button with a clear backlit symbol, making it simple to locate and use even in low-light conditions. Its rugged construction is tested to endure the vibration, temperature swings, and dust that are part of daily trucking life.
The Rear Work Light Switch is a momentary or latching push-button switch that mounts directly into the dashboard or switch panel of the Shacman H3000. It features a rugged, weather-resistant housing with a high-visibility backlit icon (typically a lamp symbol) that illuminates when the work lights are activated. The Shacman H3000 Rear Work Light Switch switch is rated for 24V DC operation and is designed to control the relay coil, ensuring that the full current of the work lights does not pass through the switch itself, which greatly enhances the switch’s reliability and lifespan. Its ergonomic design allows for easy operation, even when wearing gloves, making it ideal for drivers who frequently work in demanding conditions.
The Relay（20A/MINI） is a compact, high-performance electromagnetic relay that acts as a remote switch for the rear work light circuit. With a 20A continuous current rating, it can safely power multiple work lights or high-wattage halogen/LED lamps without overheating. The Shacman H3000 Rear Work Light Switch relay features a standard mini ISO 280 terminal layout, making it a direct replacement for the original part. Its coil is designed to operate on 24V DC with a low holding current, minimizing the load on the vehicle’s electrical system. The Shacman H3000 Rear Work Light Switch relay’s rugged construction and sealed housing protect it from dust, moisture, and vibration, ensuring dependable operation in the harsh truck environment.
The combination of the Rear Work Light Switch and the Relay provides a safe and efficient control system. The switch sends a low-current signal to the relay coil, which then closes the high-current contacts to power the work lights. This design protects the switch from arcing and heat damage, ensuring long-term durability. The relay also allows for easy integration with existing wiring harnesses, making retrofit or replacement simple and straightforward.
Both the switch and the relay are genuine Shacman parts, manufactured to the original specifications. They are tested for electrical performance, thermal cycling, and mechanical endurance to ensure they meet the same reliability standards as the components fitted when the truck was built. Using genuine parts guarantees proper fitment and compatibility with the vehicle’s electrical architecture, eliminating any guesswork.

We stock the Shacman H3000 Rear Work Light Switch and the matching relay as a complete set, ensuring you receive both components necessary for a full replacement. Our inventory is maintained to support fast shipping, so you can get your truck back to work without unnecessary delays. With our competitive pricing and commitment to quality, you can trust us to provide the genuine parts you need to keep your Shacman H3000 performing safely and efficiently.
The Shacman H3000 Rear Work Light Switch is specifically designed to control the rear work lights commonly found on dump trucks, flatbeds, and other vocational vehicles. These lights are essential for safe operation during night-time loading, unloading, and maneuvering in tight spaces. The switch provides a clear, positive action that lets the driver know the lights are engaged, and the relay ensures that the high current required by these lights does not damage the switch contacts.
When replacing a faulty switch, it is often tempting to use a generic aftermarket part. However, these parts may not have the correct electrical ratings or mounting dimensions, leading to premature failure or poor fit. Our genuine Shacman H3000 Rear Work Light Switch is an exact match for the original, featuring the same connector pinout, panel cutout size, and backlight color. This ensures a seamless replacement that looks and functions exactly as the factory intended.
The relay provided in this assembly is a standard mini ISO 280 relay, which is widely used in commercial vehicles. Its 20A rating makes it suitable for controlling multiple work lights or a single high-wattage LED work lamp. The relay’s coil draws only about 0.15A, so it can be driven directly by the switch without any additional circuitry. If your truck is equipped with factory-installed wiring for rear work lights, this relay will plug directly into the existing relay socket, simplifying the replacement process.
For fleet operators, standardizing on the genuine Shacman H3000 Rear Work Light Switch ensures that all trucks have the same reliable lighting control, which helps maintain consistency in driver experience and simplifies parts management. Our assembly is backed by a comprehensive warranty, giving you confidence in your purchase. We also provide technical support to assist with any installation or troubleshooting questions that may arise.
The switch’s backlighting is designed to match the dashboard illumination of the Shacman H3000, typically a soft green or orange, ensuring a cohesive look in the cabin. The backlight intensity is adjustable with the instrument panel dimmer, providing optimal visibility without being distracting. This attention to detail enhances the overall driving experience and contributes to the professional feel of the truck’s interior.
When installing the new switch, it is important to ensure that the relay is properly seated in its socket and that all wiring connections are secure. Loose connections can cause voltage drops, leading to dim lights or intermittent operation. Our genuine relay includes a locking mechanism that prevents it from vibrating loose, a common issue with cheap aftermarket relays. This ensures that your rear work lights will remain operational even on the roughest roads.
The Shacman H3000 Rear Work Light Switch is also compatible with LED work lights, which are becoming increasingly popular due to their low power consumption and long life. The relay’s 20A capacity is more than sufficient for LED arrays, and the switch’s momentary action can be used with a latching relay or a controller module if additional functionality is desired. This versatility makes our assembly a future-proof choice for trucks that may be upgraded to LED lighting.
To get the most out of your rear work light system, it is recommended to periodically check the condition of the switch and relay, especially if the truck operates in dusty or wet environments. Our genuine components are designed to be serviceable, and the relay can be easily swapped out if it wears out after many years of use. By keeping a spare relay and switch on hand, fleet managers can quickly address any lighting issues and minimize vehicle downtime.
