2015-2023 Ford Mustang OE-Style Mirror Turn Signal Lights

Replace a cracked, faded, moisture-affected or non-functioning exterior mirror turn signal without purchasing a complete mirror assembly. These OptiFlow Auto lamps are designed around the corresponding factory-style Mustang mirror signal location and retain a clean OE-inspired appearance.

Select the required side individually or choose the complete left-and-right pair for a consistent appearance. The driver and passenger lamps use different shapes and reference numbers, so the original lamp label, mounting tabs and connector should be checked before ordering.

Key Features

• OE-Style Replacement: Designed for buyers seeking a factory-inspired clear-lens appearance rather than a smoked or sequential modification.
• Side-Specific Construction: Separate driver-side and passenger-side lamp shapes help ensure correct installation.
• Three Purchase Options: Driver side, passenger side or a complete matched pair.
• Vehicle-Specific Design: Intended for compatible Ford Mustang exterior mirror assemblies.
• Repair-Focused Solution: Replaces the mirror lamp without requiring purchase of a complete side mirror.
• Fitment Support: Buyers may provide original lamp, connector and part-number photos for compatibility checking.
