Partsam Glass Watermelon LED Marker Tail Light — Dual-Face Amber/Red, Zinc Alloy, 12V Post-Mount

This single-unit lamp combines a distinctive glass “watermelon” lens pattern with high‑power LEDs and a rugged zinc alloy bezel to deliver bright, focused light for marker, turn, brake, and tail applications. It is engineered for simple three‑wire hookups and flexible mounting angles so fleet vehicles and owner-operators can upgrade visibility without complex wiring or custom brackets. The sealed construction resists dust, rain, and road spray while the clear glass lens sharpens the beam and emphasizes the pattern for an eye-catching look on Peterbilt, Freightliner and similar heavy-duty rigs.

How bright and visible is this light in real road conditions?

The fixture uses concentrated LEDs behind a patterned glass lens that creates crisp light lines and a starburst effect, improving side and rear recognition at night and in poor weather. The intensity is suitable for marker, stop, and turn functions on 12V truck systems without additional amplifiers.

• High-powered LEDs for strong lumen output and clear signaling
• Glass lens focuses light into a defined pattern for better recognition
• Dual-face design shows amber for markers/turns and red for tail/brake
• IP65-rated sealing keeps performance reliable in rain and road spray

How do I wire and mount the Partsam watermelon LED light?

Installation is a straightforward three-wire connection and a single post M12 bolt mount, making it compatible with common truck wiring setups. The wiring separates ground, dim/marker, and full-intensity functions so you can use the lamp as marker, turn signal, and brake light without extra relays.

• Three-wire hookup: white = ground, black = dim/marker, red = full intensity
• Post mount with M12 bolt fits standard bumper and bumper-post locations
• Can be adjusted for 90° or 180° viewing angles when needed
• No special adapters required for most heavy-truck 12V systems

Will this lamp withstand harsh environments and road debris?

The light is built with a corrosion-resistant zinc alloy bezel and a sealed glass lens, offering strong protection against moisture, dust, and grit. IP65 protection ensures the unit continues to operate in wet and dirty conditions typical of highway and off-road use.

• Zinc alloy housing resists corrosion and impact better than thin plastics
• Clear glass lens less prone to scratching and clouding than polymer lenses
• IP65-rated sealing keeps out dust and resists water jets and rain
• Robust mounting hardware withstands vibration common on heavy trucks

What fitment and uses are appropriate for this LED marker/tail light?

This Partsam lamp is sized and wired for 12V heavy vehicles and trailers and fits a range of exterior locations, from bumpers to roof edges. It serves as a flexible signaling solution whether you need a marker, turn indicator, brake light, or a combined function at the rear or side of a rig.

• Compatible with Peterbilt, Freightliner and many semi trucks and trailers
• Ideal for bumper, grille, roofline, tailgate, trailer rear and marker posts
• Single-unit solution for combined marker/turn/brake functions
• Compact footprint: approximately 5.4" high x 7" long with M12 post

Who is this for: Drivers, fleet managers, and owner-operators who need a durable, high-visibility signaling light that’s easy to fit on 12V heavy vehicles. If you want a distinctive glass-lens appearance along with reliable LED performance and weatherproof protection for marker, turn, and tail duties on semi trucks and trailers, this Partsam glass watermelon dual-face light is a practical upgrade.
