POPMOTORZ LED Fender Side Marker Lights for GMC Sierra 2500HD/3500HD (2020–2025) — 4pc Smoke Lens, CANbus Error-Free

POPMOTORZ 4PCS LED Fender Side Marker Lights are direct-fit, plug-and-play LED replacements for the front and rear side marker lamps on 2020–2025 GMC Sierra 2500HD and 3500HD trucks.

These four fender-mounted markers (two front, two rear) swap directly into the factory locations to modernize your Sierra’s look while increasing visibility. Built with a smoke lens, energy-efficient SMD LEDs, and a rugged ABS/PC housing, they match the OEM footprint and wiring so installation requires no drilling or splicing.

Will these LED markers fit my GMC Sierra 2500HD or 3500HD?

Yes — POPMOTORZ engineered these side markers as direct replacements for model years 2020 through 2025. They align with factory connectors and mounting points to simplify the swap.

• Compatible with GMC Sierra 2500HD and 3500HD (2020–2025).
• Matches OEM part references: 84806032, 84185031, GM2550207.
• Includes two front and two rear marker lamps for a complete fender refresh.

How much brighter and more durable are these LEDs compared to factory bulbs?

POPMOTORZ uses 54 SMD 4014 LED diodes per unit to produce a strong, even white output that reads noticeably brighter than stock halogen markers. The construction focuses on longevity and weather resistance so lights remain reliable in everyday and off-road conditions.

• High-power 54 SMD 4014 LEDs for increased visibility — up to about 5× brighter than OEM bulbs.
• ABS housing with PC lens rated IP67 for water and dust protection.
• Low power draw and energy-efficient operation for reduced electrical load.

Is installation difficult and will I see dash errors?

The lamps are designed for simple replacement: remove the original marker and plug the POPMOTORZ unit into the factory connector. Canbus-friendly design and non-polarity wiring reduce the chance of bulb-out warnings on modern GM systems.

• Plug-and-play, no drilling or modification required — installs in 10–15 minutes.
• Non-polarity connectors eliminate orientation worries during fitment.
• Canbus/ERROR-FREE design minimizes dashboard warning messages on most vehicles.

What comes in the box and what support is available after purchase?

• Includes 2 front and 2 rear smoke-lens LED side marker lamps (white output).
• One-year manufacturer’s warranty from date of purchase.
• Email support for pre- and post-purchase questions and fitment help.
