BYD Destroyer 05 Turn Signal & Wiper Combination Switch (Light & Wiper Combo

Product Specification

This product is professionally designed for BYD’s popular Ocean Series model—the BYD Destroyer 05, serving as a core control component that integrates vehicle lighting control and wiper control functions.

As a professional manufacturing factory specializing in automotive electronics and control system parts, our turn signal & wiper combination switch assembly strictly follows OE specifications, dedicated to providing the global aftermarket with high-reliability, long-life replacement solutions.

The combination switch assembly is mounted on the steering column, serving as the core interface between the driver and the vehicle’s lighting and wiper systems. The left lever controls lighting functions including turn signals, high/low beams, and fog lights, while the right lever controls front windshield wiper, washer spray, and wiper speed adjustment . Its operational feel, contact reliability, and durability directly affect driving experience and safety.

Compatible with all BYD Destroyer 05 models (including 2022-2025, 55KM/120KM range versions, Champion Edition, and Glory Edition). According to function button diagrams, the Destroyer 05 combination switch features a standard layout: the left side integrates lighting control (high/low beam switching, turn signals, fog lights), and the right side integrates wiper control (intermittent/low/high speed wiping, washer spray) .

• The combination switch assembly is an electronic consumable part—no fixed replacement cycle under normal conditions, replacement recommended when failure occurs.

• When turn signal failure, wiper malfunction, or washer failure occurs, prompt inspection and replacement are required.

• The combination switch involves safety-related functions (lighting + wipers) —timely repair is essential to avoid compromising driving safety.
