Partsam LED Watermelon Turn Signal Marker Light — Amber/Red Dual-Face, Zinc-Alloy Post Mount

Partsam Glass Watermelon Dual-Face Amber Red LED is a 12V post-mount combination marker and turn signal lamp with a durable zinc-alloy bezel and reversible amber/red glass lens for semi trucks and trailers.

This rugged LED lamp blends a vintage glass watermelon lens with modern LED performance to deliver a highly visible, weather-resistant signal for heavy trucks. Built for easy installation and flexible orientation, the unit uses a 3-wire hookup and an M12 mounting bolt so it can be placed on bumpers, grilles, roofs, tails, or trailers. The zinc-alloy housing and IP65-rated protection keep the electronics sealed against road grime, rain, and salt, while the starburst LED pattern and dual-color lens improve recognition at distance.

How does this lamp improve visibility in traffic?

The lamp uses high-intensity LEDs arranged behind a textured glass lens that produces a sharp starburst illumination pattern. That pattern increases contrast against ambient light and makes the signal easier to pick out from other vehicle lights. The dual-face lens supplies amber on one side and red on the other for front and rear applications.

• High-powered LEDs for bright, focused output
• Glass lens sharpens light lines for better recognition
• Dual-color lens supports both amber and red signaling
• Visible at varied angles thanks to 90°/180° mounting flexibility

What mounting and wiring options does it offer?

Installation is straightforward: the lamp fastens with an M12 bolt and accepts a simple 3-wire connection for ground, dim/marker, and full-intensity stop/turn signals. The bezel and housing accommodate post mounting and can be angled to suit bumper, roof, or grille placements. No complex relays or adapters are required for most 12V truck electrical systems.

• M12 bolt post mount for quick attachment
• Three-wire hookup: ground, dim/marker, full intensity
• Adjustable orientation: fits 90° or 180° applications
• Works with standard 12V truck electrical systems

Is this lamp built to withstand road conditions and weather?

The assembly pairs a corrosion-resistant zinc-alloy housing with a sealed glass lens to meet IP65-level protection against water and dust intrusion. That combination shields the LEDs and wiring from rain, salt spray, and airborne debris common to heavy-duty use. Routine highway exposure will have minimal impact when mounted correctly and sealed at the post.

• Zinc-alloy bezel and chrome-plated housing resist corrosion
• Glass lens provides scratch and UV resistance compared to plastics
• IP65 rating blocks dust and protects against water jets
• Designed for long-term use on trucks and trailers

What vehicles and locations are appropriate for this lamp?

This lamp is designed for 12V commercial vehicles such as Peterbilt, Freightliner, and other semi trucks and trailers. Because it offers both amber and red signaling, it is suitable for front marker, rear marker, brake/turn, bumper, grille, roof, and tailgate positions. The compact footprint makes it an adaptable choice for custom mounting projects and fleet upgrades.

• Compatible with Peterbilt, Freightliner, and similar 12V trucks
• Ideal for bumpers, grilles, roofs, tailgates, and trailers
• Works as marker, turn, and stop/brake light
• Good for retrofit, replacement, or new installations

Who is this for: Professional drivers, fleet managers, and DIY truck owners who want a durable, highly visible signaling light that combines classic glass styling with modern LED technology. If you need a weatherproof, easy-to-install post-mount lamp that supports both amber and red applications on 12V commercial vehicles, this Partsam unit offers a practical, long-lasting option.
