AUTOONE LED Side Mirror Marker Lights for 2008–2016 F-Series Super Duty — Smoke Lens, Sequential Switchback (2pcs)

A plug-and-play LED side mirror marker light pair for 2008–2016 Ford F250/F350/F450/F550 Super Duty that delivers white running/parking illumination and a dynamic amber sequential turn signal in a smoke lens housing.

These AUTOONE sequential switchback mirror marker lights replace the factory side mirror indicators with a brighter, more durable LED assembly designed to match OEM fitment (fits factory part numbers 7C3Z-13776-A/B / 7C3Z13776A/B). Built with impact-resistant ABS housing, a PC lens and IP67-rated sealing, they offer long life and weather resistance while improving visibility and appearance for the Super Duty series.

How do these lights improve visibility and signaling?

The LEDs use modern high-output chips that produce a substantially brighter white running light and a clear amber sequential turn pattern. Brighter illumination improves daytime recognition and makes your turn intent easier to see for nearby drivers.

• 600% brighter than standard bulbs for parking/running light use
• Dynamic amber sequence for clearer turn signaling
• White switchback mode for daytime position lighting
• High-contrast smoke lens for a refined look without losing signal clarity

Will these fit my 2008–2016 Ford Super Duty side mirrors and how is installation?

AUTOONE designed these units as direct replacements for the OEM mirror marker assemblies, matching the listed factory numbers for straightforward swapping. Installation is plug-and-play; remove the mirror carefully and swap the housing, then reconnect—no complex wiring required.

• Direct replacement for OEM part numbers 7C3Z-13776-A/B
• No splicing or extra adaptors for compatible mirror harnesses
• Designed to avoid fault codes, flicker, and radio interference
• Customer support available if you need installation guidance

What build quality and weather protection do these mirror lights offer?

The assemblies use reinforced ABS for the housing and a polycarbonate lens to resist impact and abrasion while keeping the LEDs sealed from moisture and dust. An IP67 ingress rating means they withstand rain and road spray so the lighting remains reliable in varied conditions.

• ABS housing and PC lens for shock and scratch resistance
• IP67 waterproofing to prevent moisture intrusion
• Durable soldering and potting to protect LED chips
• Estimated 50,000-hour LED lifespan under normal use

What performance can I expect long-term and is there maintenance?

These LEDs are engineered for low-maintenance operation and long service life compared with halogen bulbs. Routine care is limited to cleaning the lens; the robust components and long-life diodes reduce replacement frequency and downtime.

• LED life rated around 50,000 hours for extended use
• Low heat output and efficient energy draw from the vehicle circuit
• Minimal upkeep beyond occasional lens cleaning
• Replacement pair sold as 2PCS for both sides

Who is this for: These AUTOONE LED sequential switchback mirror markers are aimed at Ford Super Duty owners (2008–2016 F250/F350/F450/F550) who want a direct-fit upgrade for brighter running lights and modern sequential turn signals while maintaining rugged, weatherproof construction. They suit drivers who value improved visibility, a sleeker smoked appearance, and a long-lived, plug-and-play replacement that installs without rewiring.
