A-Premium Multi-Function Turn Signal Switch for Volvo VNL/VN 2005–2012 — 14-pin Plug‑In Headlight Dimmer

A-Premium's multi-function turn signal switch is a direct-replacement control module for Volvo VNL/VN trucks (2005–2012) that manages turn signals, headlight dimming, cruise/PTO adjustments and hazard/high-beam functions from one under-steering-wheel stalk.

This compact, rebuild-ready switch is engineered to restore or upgrade your truck's left-side steering column controls without rewiring. Designed to match factory fit and function, it connects via a 14-pin male terminal and carries clear white markings for each function so drivers can operate signals, change headlight beams, trigger the high-beam flasher, and adjust PTO/cruise settings intuitively.

What functions does this switch combine into a single stalk?

The A-Premium unit consolidates several driver controls into one ergonomic module for convenience and faster troubleshooting. It handles turn signaling, headlight beam selection and flashing, PTO speed adjustments, cruise control interactions, and hazard activation.

• Turn signals: left/right signaling with return-to-center action
• Headlight controls: latching high beams and momentary flash
• PTO speed and cruise control adjustments
• Hazard lights operation via integrated switch
