The Wacker Neuson 5200021794 Lights Kit is a genuine OEM lighting assembly designed for the APT4T, APT6T, and APT8T series self-priming centrifugal trash pumps, covering both standard and Cold Weather configurations with either Surge Brake or Electric Brake setups. As a factory-sourced component, this kit is built to exact OEM specifications, ensuring proper fit and function across the full range of compatible APT pump models. The 5200021794 is the correct replacement when trailer lighting fails, dims, or shorts out — keeping the pump unit road-legal and site-ready. Verify your machine number against the fitment list before ordering to confirm this is the right kit for your configuration.
Key Features
- Genuine OEM Wiring and Lamp Spec — Factory-sourced components meet the original electrical output and connector spec, so trailer lights perform exactly as the unit left the factory.
- Broad APT Series Coverage — Fits APT4T, APT6T, and APT8T pump models across standard, Cold Weather, Surge Brake, and Electric Brake variants — one kit number covers a wide range of configurations.
- Direct-Connect Installation — Designed to connect to existing trailer wiring harness points on the APT platform without reworking the harness or sourcing adapter connectors.
- Road-Legal Lighting Compliance — Trailer lighting is a DOT requirement for highway towing. Replacing a failed lights kit with a correct OEM unit keeps the pump trailer in legal towing compliance.
- Prevents Towing Delays and Site Interruptions — A failed trailer light set grounds the unit until repaired. Stocking or promptly replacing the 5200021794 keeps the pump moveable between job sites without regulatory hold-ups.
The Lights Kit on an APT series pump trailer provides the required running, brake, and turn-signal illumination for legal road transport between job sites. Trailer lighting wears out over time through vibration, moisture exposure, and connector corrosion — common conditions on a pump unit that operates in wet, muddy environments. When lights fail, flicker, or fail to meet DOT requirements, replacing the complete kit with the correct OEM assembly is the fastest way to restore compliant operation and get the trailer moving again.
