Product Overview
Sometimes a product doesn’t quite make the perfect cut — but still deserves a spot on your truck.
This Amber/Purple Watermelon LED Marker Light combines the classic 3.5″ watermelon lens look with a dual-color LED setup, giving you the ability to switch between amber and purple lighting depending on your wiring configuration.
It’s bold. It’s unpredictable. And at this price, it’s hard not to try one.
Key Features & Benefits
Dual-Color LED Lighting
This light can illuminate in amber or purple, depending on how the wiring is configured. Purple provides a custom show-truck glow, while amber delivers a traditional marker light color.
Classic 3.5″ Watermelon Lens Design
The clear dome lens features a starburst reflector pattern that spreads LED light evenly for a signature watermelon-style glow.
19 LED Internal Light Array
Nineteen LEDs provide strong illumination behind the lens for a bright marker-light appearance.
Standard Watermelon Mount Compatibility
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 the reflector cup, lock ring, and pigtail wiring leads needed for installation.
Performance / Compatibility / Use-Case
Works with 12V DC vehicle electrical systems.
Compatible with standard 3.5″ watermelon light mounts commonly found on:

Installation / Fitment / Technical Details
This dual-color light requires proper wiring to control each LED color separately.
Typical wiring setup
-
One lead powers the amber LED mode
-
One lead powers the purple LED mode
-

⚠️ Important:

Frequently Asked Questions
How do I select amber or purple?
Each color has its own power lead, with a shared ground. Wire the amber and purple 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/purple 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 are moisture intrusion, early LED burnout and diode inconsistency.
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.
