Partsam LED Fender/Bed Side Marker Lights for Silverado/Sierra 1999–2013 — 2 Amber + 2 Red, T10 Plug

These Partsam 4-piece LED fender/bed side marker lights replace factory amber and red markers on dual-wheel Silverado and Sierra 2500/3500 HD trucks (1999–2013) to deliver brighter, longer-lasting illumination.

If you own a dually Silverado or Sierra and want clearer front and rear side marker visibility, this kit swaps in compact LED modules that fit the original marker locations. The set includes two amber lamps for the front and two red lamps for the rear, each driven by three high-intensity Flux LEDs. They’re sized to match common OEM pockets and come with T10 plug harnesses and double-sided tape to simplify mounting and wiring.

Will these LED markers fit my Silverado or Sierra dually?

They are designed to match many 2500/3500 HD dual-wheel trucks from model years that commonly use these marker pockets. Fitment covers a wide range of Silverado and Sierra 2500/3500 trucks but may require minor wiring or connector changes on some vehicles. Confirm your truck’s marker lens shape and mounting space before purchase.

• Intended for many 1999–2013 Silverado/Sierra 2500 and 3500 dual-wheel trucks
• Direct replacement size: approximately 81.0 x 38.5 x 19.5 mm
• May require cutting off factory plugs or reversing polarity for proper operation
• Also adaptable to other truck models with small modifications

How easy is installation and what hardware is included?

The kit ships with T10 plug connectors and double-sided tape so you can mount and connect the lights without extensive fabrication. If your vehicle uses a different connector, the plugs are simple to remove and the wires can be spliced into the existing harness. Installation is straightforward for a basic DIY wiring job or a quick shop install.

• Includes two amber and two red LED marker units
• T10 168/194 connector plugs and adhesive tape supplied
• Simple polarity flip will correct non-lighting LEDs
• Connector removal allows direct splicing if sockets differ

How bright and durable are the LEDs compared with stock bulbs?

Each marker uses three super-bright Flux LEDs to provide a crisp, attention-getting light that typically outperforms incandescent side marker bulbs in visibility and lifespan. The solid-state LEDs reduce heat and are less likely to fail from vibration or shock that trucks commonly experience. However, avoid claiming specific lifetimes—LEDs generally last far longer than filament bulbs under normal conditions.

• Three high-output Flux LEDs per unit for improved visibility
• Lower heat and greater vibration resistance than incandescent bulbs
• Consistent color output: amber for front, red for rear markers
• Polarity sensitive — flip 180° if LED does not illuminate initially

Who this is for: This 4-piece Partsam LED side marker set is intended for Silverado and Sierra dually owners who want brighter, longer-lasting front and rear side markers without extensive modification. It suits DIYers comfortable with basic vehicle wiring as well as shops performing quick upgrades. If your truck’s side marker cavities and lens colors match amber front/red rear and you’re willing to trim connectors or reverse polarity when necessary, this kit offers a cost-effective visibility upgrade.
