Hopkins Electronic Taillight Converter (48845)

$10.99

The Hopkins 48845 Taillight Converter is a high-performance electronic module that adapts 3-wire vehicle electrical systems to standard 2-wire trailer wiring. This converter protects your vehicle’s sensitive onboard electronics by drawing power directly from the battery (if required by your specific harness) and utilizing advanced integrated circuitry. It effectively combines the independent brake and turn signal pulses from your car into a single “stop/turn” signal required for most trailers, ensuring your towing setup is safe and street-legal.

Full Product Description

The Hopkins 48845 model is engineered to solve the “wiring mismatch” common in many import and modern domestic vehicles. It features short-circuit protection and over-current safeguards, which act as a firewall to prevent a trailer-side electrical fault from damaging your vehicle’s expensive lighting control modules.

The unit is encased in a weatherproof, potted housing that protects the internal electronics from moisture, dust, and vibration. Its universal design includes color-coded wires that follow industry standards, making it compatible with a wide range of sedans, SUVs, and compact trucks. The converter is rated for a total of 8.0 amps per circuit for turn/brake lights and 10.0 amps for the taillight circuit, providing plenty of power for even large trailers with multiple incandescent or LED bulbs.

Key Features & Benefits

  • Adapts 3-Wire to 2-Wire: Converts independent vehicle turn and brake signals into the combined signal used by 4-way flat trailer plugs.

  • Circuit Protection: Built-in safeguards protect your vehicle’s computer and wiring from trailer-side shorts or overloads.

  • LED & Incandescent Compatible: Works flawlessly with both traditional bulbs and modern, low-draw LED trailer lights.

  • Weatherproof Construction: The electronic components are “potted” (sealed in resin) to ensure 100% protection against the elements.

  • Universal Wiring: Features standardized color-coding for a straightforward installation process on almost any vehicle.

  • High Power Capacity: Handles up to 8 Amps for stop/turn signals, allowing for multiple lights without dimming or flickering.
