Product Overview
Sometimes a product doesn’t pass every quality test — but may still suit a custom display project.
This Amber/Green Watermelon LED Marker Light combines the iconic 3.5″ watermelon cab light look with a dual-color LED system that lets you switch between amber and green illumination depending on your wiring setup.
It’s loud, colorful, and slightly unpredictable — but at this price, that’s part of the fun.
Key Features & Benefits
Dual-Color LED Lighting
Switch between amber and green illumination depending on how the light is wired.
Amber offers a traditional marker-light look, while green adds bold custom styling.
Classic Watermelon Lens Styling
The clear domed lens with starburst reflector pattern creates the classic watermelon glow that truckers have loved for decades.
19 LED Internal Array
Nineteen LEDs provide bright output behind the clear dome lens.
Standard 3.5″ Watermelon Mount
Designed around the listed 3.5-inch watermelon mounting format. Compare the existing bucket, lock-ring interface and wiring clearance before ordering; the truck make alone does not confirm the fit.
Included Mounting Parts
Includes reflector cup, lock ring, and pigtail wiring leads to simplify installation.
Performance / Compatibility / Use-Case
Designed for 12V DC vehicle electrical systems.
Compatible with standard 3.5″ watermelon light mounts commonly used on:
-
Semi trucks
-
Cab light bars
-
Custom pickup builds
-
Parade trucks
-
Trailer lighting systems
Green lighting may be restricted for on-road use depending on location.
Installation / Fitment / Technical Details
This dual-color light allows independent control of each LED color.
Typical wiring setup:
-
One lead powers the amber LEDs
-
One lead powers the green LEDs
-
Ground wire completes the circuit
⚠️ Important
If both power leads are energized at the same time, both colors will illuminate simultaneously.
Using a 3-position switch or separate toggles is recommended.

Frequently Asked Questions
How do I select amber or green?
Each color has its own power lead, with a shared ground. Wire the amber and green leads to the intended switching arrangement so the desired color can be selected.
What happens if both color leads receive power?
Both colors illuminate simultaneously on this older Alpha-W product. Do not assume the color-priority or brightness behaviour of a newer Glass Is Class Gen 2 Duo bulb.
What should I measure before ordering?
This light lists a 3.5-inch watermelon mounting format. Compare the bucket, reflector cup, lock-ring interface and rear wiring space with the actual installed light; the lens size alone is not a complete fit check.
Does it work on a 24V circuit?
This exact listing specifies 12V DC. Do not treat it as a 24V light merely because other truck accessories accept both voltages.
Which parts come with one light?
One amber/green dual-color LED marker light, reflector cup, lock ring and pigtail wiring leads are listed. Plan any switches, vehicle wiring and additional mounting needs for the installation.
Does this clearance light include warranty or return coverage?
No. These lights are sold as-is with no warranty and no returns due to quality control issues. The disclosed possible issues include lens fogging, LED flickering and early LED failure.
Where should I look for the current Glass Is Class range?
Compare Glass Is Class Gen 2 for a new custom marker or accent project. It is a different product generation with its own mounting, wiring and warranty terms. Match the exact selected assembly to the project.
