Ronybuy 2.5" 13-LED Round Trailer Marker Lights - 10-Pack (5 Amber/5 Red), Sealed Flush-Mount

Ronybuy 2.5" 13-LED round marker lights are a sealed, flush-mount kit of 10 (five amber, five red) designed as bright, weatherproof side/clearance lights for trucks, trailers and RVs.

These 2.5-inch LED clearance/marker lamps combine 13 LEDs per light with integrated mini reflectors, rubber grommets and 2-prong pigtails so you get a ready-to-install solution for common 12V vehicle applications. The set includes both front/side amber and rear red markers so you can outfit multiple mounting points at once. They are DOT-certified, dust- and waterproof, and built to withstand typical road and weather exposure while delivering a focused beam pattern for improved visibility.

How bright are these Ronybuy 13-LED marker lights for night driving?

Each lamp uses 13 compact LEDs and internal mini reflectors to concentrate the beam, producing a sharp, visible glow that improves detectability on dark roads. They’re engineered to throw more directed light than a simple single-LED lamp while also providing passive reflectivity when not powered.

• 13 LEDs per unit for increased luminous output
• Mini reflector array to focus light and enhance visibility
• Sealed housing resists fogging and maintains consistent performance

What’s included and how easy is installation?

The kit contains ten 2.5" lights (5 amber, 5 red), ten rubber grommets and two-prong wire pigtails pre-attached to each lamp — everything needed for a flush-mount install. The lights are plug-and-play for 12V systems: white wire to ground, black wire to positive; just prepare the proper hole and seat the grommet for a secure fit.

• Full kit: 5 amber + 5 red lamps with grommets and pigtails
• Mounting dimensions: outer diameter with grommet 3.4", light face 2.5"
• Recommended hole size: roughly 2.6"–2.67"; pigtail length ~7.6"

Will these lights work on my truck, trailer, or RV and hold up outdoors?

Yes — the Ronybuy markers are built for typical 12V vehicle systems and common placement on tractors, trailers, RVs and utility vehicles. The sealed construction is designed to keep out dust and moisture so the lamps remain reliable through rain, road spray and seasonal temperature changes.

• Meets DOT/SAE-style requirements for trailer lighting harnesses
• Waterproof and dustproof sealed housing for outdoor durability
• Wide compatibility: side markers, clearance lights, bumper and panel use

How do I choose where to mount amber and red units?

Amber markers are normally fitted to the front and side positions to indicate vehicle width and direction, while red markers are used on the rear or outermost back corners to show the vehicle’s trailing edge. Plan placement to meet local lighting regulations and to provide continuous visual guidance along the vehicle’s length.

• Amber for front/side clearance and width indication
• Red for rear clearance and rearward visibility
• Install evenly spaced along sides and at outer rear corners for continuity

Who is this for: The Ronybuy 10-piece marker light kit is aimed at owners and operators of trailers, flatbeds, box trucks, RVs and utility vehicles who want a straightforward, reliable upgrade or replacement set. It’s well suited for DIY installers and fleet mechanics who need a complete, plug-and-play solution with weatherproof construction and clear, focused lighting for safer night and poor-weather driving.
