Product Overview
Dual‑color red/white watermelon lights are common, but most rely on clusters of LEDs and plastic lenses. For instance, the Trux Dual Revolution Red/White watermelon light uses 19 high‑performance LEDs, a clear polycarbonate lens and a bullet‑connector harness; it runs at 12 V only and is DOT compliant. The RoadWorks Red to White light also features a clear polycarbonate lens and uses 4‑wire bullet connectors, with an all‑weather foam gasket included. Mini lights like the Double Fury series use a high‑quality injection‑molded polycarbonate lens, only 4 LEDs, a plastic bezel and a 12 V, 3‑wire hookup. These products offer basic dual‑color functionality but lack the intense output, dual‑voltage capability and durability needed for premium applications.
The Gen 2 Red/White Glass is Class light solves these issues by combining a tempered‑glass star lens with a powerful AlphaFit G2 white LED bulb. The red lens tints the white light, giving a lighter red hue than a red/red light and matching clear lens builds. Its 3‑wire design allows marker and high‑power signal modes on 12 V or 24 V systems. Advanced heat dissipation and positive‑pressure venting prevent condensation and overheating, while the IP68 seal ensures moisture and dust stay out. Whether you’re illuminating a custom tractor, semi‑truck or show car, this Gen 2 light delivers unique style and uncompromising performance.
Key Features & Benefits
Red Lens with White LED Chip – Lighter Red Hue
The tempered‑glass lens is tinted red, while the white AlphaFit G2 LED shines through, producing a lighter, more translucent red than a red/red combo. This makes it perfect for builds with clear lenses or chrome accents. The star‑burst prisms in the lens amplify and diffuse the light into a wide, sharp beam with no dark voids—unlike multi‑LED lights with visible individual diodes.
Dual‑Function AlphaFit G2 Bulb (Marker & Signal)
The AlphaFit G2 H11‑base bulb offers both a 15 W marker mode and a 20 W high‑power signal mode via its three‑wire harness. Many competitor lights use a standard 1157 or 3‑wire bullet connector limited to 12 V. The G2’s built‑in driver works on 12‑V and 24‑V systems, delivering consistent brightness across vehicle types.
Advanced Heat Dissipation & Positive‑Pressure Cooling
Just like the other Gen 2 variants, this light features a radiator‑fin heat sink, an internal cooling fan and four check‑valve vents that create positive pressure to expel condensation. The anodized‑aluminum body acts as a thermal reservoir, allowing continuous operation at full 20 W output without overheating. Competitor dual‑color lights with polycarbonate lenses and clusters of LEDs often lack such sophisticated cooling.
Real Tempered‑Glass Star Lens & Optimised Beam Pattern
Instead of polycarbonate, this light uses a tempered‑glass lens that resists scratches and yellowing. The straight PCB design of the AlphaFit bulb and the star‑burst pattern project a uniform beam free of pixelation. Polycarbonate lenses on dual‑revolution lights can crack and may scatter light unevenly.
IP68 Weatherproof & Anodized‑Aluminum Housing
The Gen 2 housing employs a silicone gasket, anodized‑aluminum base and check‑valve vents to achieve an IP68 rating. It is dust‑tight and can endure water submersion. By contrast, mini dual‑color lights feature only IP67 water resistance. The anodized finish enhances corrosion resistance and heat dissipation.
Universal Fit & 12/24‑Volt Compatibility
The standard H11 base and slim design allow this light to fit into existing watermelon‑light brackets or tight spaces. The three‑wire pigtail (black = ground, blue = marker, yellow = high) makes wiring simple, and built‑in electronics support 12 V or 24 V systems. Competitors like the Trux Dual Revolution require 12 V only and rely on bullet connectors.
New Color Options & Flexible Customisation
Besides Red/White, the Gen 2 Glass is Class lineup offers Red/Red, Amber/Amber, Amber/White, Clear/Amber, Clear/Red and Clear/White options. This range lets you choose the perfect combination of lens tint and LED color for your custom build.
Performance / Compatibility / Use-Case
The Gen 2 Red/White light is engineered for maximum versatility. The white LED, tinted by the red glass, produces a bright, lighter red marker and an intense high‑power signal for brake or turn functions. This single high‑output chip surpasses the brightness of 19‑LED clusters while consuming comparable power. Its dual‑voltage capability means it can be installed on semis, tractors, pickup trucks and show cars without voltage converters. Positive‑pressure vents keep the interior dry, making the light suitable for humid or cold climates.
Installation / Fitment / Technical Details
Mount the light using your existing watermelon‑light bracket (sold separately). Connect the three‑wire pigtail: black to ground, blue to marker/running light (15 W), and yellow to brake/turn/high‑power circuit (20 W). To run at full intensity continuously, tie the yellow wire into your marker circuit and cap the blue wire. The light is compatible with 12 V and 24 V systems and uses a standard H11 base for easy bulb replacement.
Build Quality / Warranty
Every Gen 2 light is assembled with a tempered‑glass lens, anodized‑aluminum housing, internal fan, radiator fins and positive‑pressure vents. These components provide durability, efficient heat management and moisture resistance. The light includes a one‑year warranty, which is more generous than the 6‑month warranties found on some flush‑mount kits and comparable to or better than warranties on competitor dual‑color lights. Like all Glass is Class products, this light is extremely bright and not SAE/DOT approved.
Warranty: 1-Year Limited Warranty

Frequently Asked Questions
How does the Red/White variant differ from Red/Red and Clear/Red options?
The Red/White light pairs a red tempered‑glass lens with a white LED chip. The result is a lighter red output compared with the Red/Red light, which uses a red chip for the darkest red possible. The Clear/Red variant uses a clear lens with a red chip, giving a brighter red with less tint. All variants share the same AlphaFit G2 bulb, dual‑function wiring and IP68 construction.
Will the red glass lens and white LED combination look pink?
No. The red tempered‑glass lens filters the white LED into a lighter but still vivid red. It will not appear pink; instead, the output matches clear lenses on your rig, offering a crisp red hue with high brightness.
Can I run this light on a 24‑volt truck or tractor?
Yes. The AlphaFit G2 bulb supports 12 V and 24 V systems. Simply wire the pigtail as instructed and it will operate safely at either voltage without resistors.
Is the light waterproof and suitable for pressure washing?
Yes. The Gen 2 light achieves an IP68 rating thanks to its silicone gasket, anodized‑aluminum base and check‑valve vents. It can withstand dust, dirt and water submersion, making it safe to pressure wash around the light.
Are these lights street‑legal?
No. Like other Glass is Class products, this light is designed for off‑road and show use and is not SAE/DOT approved. Dual‑color lights such as the Trux Dual Revolution are DOT compliant, but they do not offer the same intensity or tempered‑glass construction.
Can I change the bulb or LED color later?
Yes. The light uses a standard H11 base, so you can replace the AlphaFit G2 bulb with another color or a replacement bulb when available. Simply remove the old bulb, insert the new one and reconnect the pigtail.
