Gempro LED Dually Fender Side Marker Lights for 2001–2014 Silverado/Sierra Dually — Smoked Amber/Red 4‑Pack

If you drive a dual-rear-wheel (dually) Silverado or Sierra from the 2001–2014 model years and your rear fender markers are faded, cracked, or simply too dim, these Gempro LED units offer a simple, reliable upgrade. Designed specifically for 4-rear-wheel dually beds, the set includes four sealed lamps with high-efficiency SMD LEDs and smoked lenses for a modern, low-profile look that maintains required visibility.

How do these Gempro dually marker lights improve nighttime visibility?

The Gempro units use SMD LED chips that produce brighter, more consistent illumination than traditional incandescent bulbs. Brighter markers help other drivers spot the wider footprint of a dually truck at night and in low-light conditions without drawing excessive current from the vehicle.

• 5× higher perceived brightness compared to stock incandescent markers.
• Stable, no-flicker output thanks to error-free LED design.
• Low power consumption preserves vehicle electrical load.

Will these fit my truck and how hard is installation?

These Gempro lights are engineered for 2001–2014 Chevy Silverado and GMC Sierra 2500HD/3500HD dually (4-rear-wheel) models only; they do not fit single-rear-wheel versions. Installation is plug-and-play using the OEM connector, so no cutting, splicing, or housing modification is required.

• Compatible: Chevy Silverado & GMC Sierra 2500HD/3500HD dually (2001–2014).
• Not compatible with single rear-wheel models—verify before purchase.
• Typical install time: under 15 minutes per side; no wiring tools needed.

What are the build quality and weather protections?

Gempro constructed these side markers with a durable ABS housing and a tough polycarbonate (PC) lens to resist impacts and UV damage. Each lamp is weather-sealed to be waterproof, dustproof, and shockproof, intended for heavy-duty truck environments and long service life.

• Lightweight, impact-resistant ABS plastic body for rugged use.
• PC lens resists yellowing and scratches while maintaining clarity.
• Waterproof and dustproof sealing for reliable performance in harsh conditions.

What does the package include and what warranty is offered?

The package contains four Gempro rear fender side marker lamps—enough to replace all dually bed markers at once. Gempro backs these lights with a 12-month warranty and offers customer support for installation questions or product quality concerns.

• Included: 4 rear wheel side marker lights (amber/red smoked lens).
• Warranty: 12-month coverage from the date of purchase.
• Support: direct assistance available for fitment or installation guidance.

Who is this for? These Gempro LED dually fender side marker lights are aimed at owners of 2001–2014 Chevy Silverado and GMC Sierra 2500HD/3500HD trucks with dual rear wheels who want a brighter, longer-lasting, and visually updated replacement for OEM rear bed marker lights. They suit truckers who prefer a straightforward, no-modification swap, fleet managers replacing aged markers, and enthusiasts seeking a smoked aesthetic without sacrificing visibility or durability.
