POPMOTORZ LED Fender Side Marker Lights for GMC Sierra 2500HD/3500HD (2020–2025) — 4PC Smoked Lens CANbus

POPMOTORZ 4-piece LED fender side marker kit replaces the OEM halogen markers on 2020–2025 GMC Sierra 2500HD and 3500HD trucks with brighter, smoke-lens LED units for improved visibility and a modern look.

Upgrade your Sierra’s exterior lighting with a direct-fit set designed to swap into the factory locations without drilling or splicing. These four LED markers (two front, two rear) use concentrated SMD chips behind a smoked lens and a weatherproof housing, giving your pickup a cleaner, more commanding presence while meeting the practical need for clearer side illumination.

How much brighter are these LEDs compared to the stock bulbs?

These marker lamps use high-density 4014 SMD diodes that output substantially more visible light than standard halogen side markers. Expect a noticeably stronger, whiter beam that improves side visibility during low-light driving.

• 54 SMD 4014 LED chips per unit for concentrated output
• Estimated multi-fold increase in perceived brightness versus OEM bulbs
• White color temperature for clearer contrast at night

Will they fit my GMC Sierra without modifications?

Yes — the POPMOTORZ set is built as a plug-and-play replacement for the factory side marker lamps on compatible Sierra models. Each lamp matches the OEM mounting points and electrical connectors so installation is quick and reversible.

• Direct replacement for OEM part numbers 84806032, 84185031, GM2550207
• Non-polarity design simplifies wiring during swap
• Typical install time: 10–15 minutes per lamp, no drilling needed

Are these lights durable and weather-resistant for everyday use?

The housings combine ABS plastic with a polycarbonate lens to resist impacts and UV exposure. They’re rated to withstand moisture and road conditions so you can rely on consistent performance in varied weather.

• Robust ABS housing paired with a PC (polycarbonate) lens
• IP67-level protection against water and dust penetration
• Low power draw for efficient operation and long service life

Do these markers create error codes or hyper-flash on modern GMCs?

These markers include CANbus-compatible circuitry designed to prevent dashboard bulb-out warnings and typical error messages. The units are engineered to operate without additional resistors or controllers on supported Sierra models.

• Built-in CANbus design to minimize error signals
• Error-free operation on compatible GMC electrical systems
• Plug-and-play electrical fit reduces troubleshooting

Who this is for: These POPMOTORZ LED fender side markers suit Sierra 2500HD and 3500HD owners from model years 2020–2025 who want a straightforward exterior upgrade that increases side visibility and modernizes the truck’s appearance. If you prefer a smoke-lens aesthetic, need a direct OEM-fit replacement, and want a durable, weatherproof LED solution with a one-year manufacturer warranty, this kit is a practical choice.
