DERMOKA LED Side Marker Lights for GMC Sierra 2500HD/3500HD (2020–2025) — White, Plug-and-Play Set of 4, DOT/SAE

DERMOKA LED Side Marker Lights are direct-fit white LED fender markers with smoked lenses designed to replace OEM side marker lamps on 2020–2025 GMC Sierra 2500HD and 3500HD trucks.

These plug-and-play side marker lights give your Sierra a brighter, modernized appearance while keeping installation straightforward. Built from durable ABS housing and tough polycarbonate smoked lenses, the set of four LEDs operates at 12V, outshining stock bulbs and meeting DOT & SAE standards for road use. The lamps are engineered to match the factory fitment for front and rear fender placements, with non-polarity connections to avoid wiring hassles.

How bright are these LEDs compared with the original bulbs?

The DERMOKA markers use high-power LED chips that produce about five times the output of typical OEM filament bulbs. That added brightness improves daytime visibility and makes the side profile of the truck more noticeable at night.

• LED color: crisp white for clear side-marker illumination
• Rated approximately 5x brighter than stock bulbs
• Long-life LEDs—typical lifespan over 55,000 hours
• DOT & SAE certified for regulated use

How easy is installation and what comes in the package?
