Product Overview
Many clear‑lens/white LED watermelon lights rely on clusters of small LEDs and basic wiring. For instance, Alpha Series Lighting’s Dual Function Glass Watermelon Flush Mount Kit uses a dual‑function 1157 LED bulb, a stainless steel flush mount bezel and foam gasket, and runs on 12 V DC. The kit includes a pre‑installed white 1157 bulb, mounting hardware and a 3‑wire metal ground lead, but its warranty is only six months. Budget “Double Fury” mini lights use a 4‑LED cluster and a 12 V, 4‑wire hookup, where the secondary colour overrides the primary when activated. These products deliver a basic white glow but lack the intense output, dual‑voltage support, thermal management and durability needed for high‑end builds.
The Gen 2 Clear/White Glass is Class light solves these problems. Its AlphaFit G2 LED features a single high‑output chip and a compact PCB that projects through a true tempered‑glass star lens, eliminating the dark voids seen in multi‑LED lights. The three‑wire design offers low‑power marker and high‑power signal modes, and the integrated driver works on 12 V or 24 V systems. An anodized‑aluminum body, internal cooling fan, radiator fins and positive‑pressure vents dissipate heat and expel condensation. Coupled with IP68 sealing and a one‑year warranty, this light provides unmatched brightness, reliability and versatility.
Key Features & Benefits
Clear Lens with White LED Chip – Crisp White Output
A crystal‑clear tempered‑glass lens and a pure white AlphaFit G2 LED combine to produce a bright, neutral white beam. The star‑burst prisms inside the lens amplify and spread light evenly, creating sharp lines and a uniform glow without the pixelation found in 4‑LED clusters.
Dual‑Function AlphaFit G2 Bulb (Marker & Signal)
The AlphaFit G2 features a three‑wire harness that delivers 15 W on the marker circuit and 20 W on the high‑power circuit. Unlike competitor lights that use standard 1157 bulbs or 4‑wire LED modules limited to 12 V, the G2 operates on 12 V and 24 V systems. You can wire the high‑power line permanently for maximum intensity or use it only for turn/brake signals.
Advanced Heat Dissipation & Positive‑Pressure Cooling
An oversized anodized‑aluminum body with a radiator‑fin heat sink, a quiet internal cooling fan and four check‑valve vents maintain safe operating temperatures even at full 20 W output. The vents create positive pressure inside the light, pushing out condensation and preventing moisture intrusion—features absent from basic flush‑mount kits and mini lights.
Real Tempered‑Glass Star Lens & Optimised Beam
Instead of polycarbonate, this light uses a tempered‑glass lens that resists scratching and yellowing. The star‑burst design focuses the single LED’s output into a wide, sharp beam with no dark voids. Competing lights with 1157 bulbs or 4‑LED clusters scatter light and rely on multiple diodes to approximate brightness.
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 withstand water submersion. By contrast, many kits carry IP67 ratings or lack any active cooling.
Universal Fit & 12/24‑Volt Compatibility
The standard H11 base and slim profile allow this light to fit existing watermelon‑light brackets or tight spaces. The three‑wire pigtail (black = ground, blue = marker, yellow = high) simplifies wiring, and the internal driver supports 12 V or 24 V operation. No resistors or converters are needed, unlike 12 V‑only kits.
New Colour Options & Flexible Customisation
The Gen 2 lineup includes Amber/Amber, Amber/White, Clear/Amber, Red/Red, Red/White, Clear/Red and Clear/White variants, letting you match your rig’s aesthetic perfectly. All share the same AlphaFit G2 bulb and IP68 housing.
Performance / Compatibility / Use-Case
This light delivers pure white illumination for both marker and signal functions. The 15 W marker mode provides a bright running light, while the 20 W high‑power mode produces an intense white flash for turn signals or brake lights. The single chip and star lens ensure a cleaner, more consistent beam than 4‑LED or 19‑LED clusters. Its dual‑voltage compatibility means it’s suited for semi‑trucks, tractors, custom hot rods and show vehicles. Positive‑pressure vents keep the interior dry, making the light reliable in humid, rainy or cold environments.
Installation / Fitment / Technical Details
Mount this light using your existing watermelon‑light bracket (not included). Connect the three‑wire pigtail: black to ground, blue to marker/running (15 W), and yellow to brake/turn/high (20 W). To run at full brightness all the time, tie the yellow wire into your running circuit and cap the blue wire. The H11 base makes bulb replacement easy, and built‑in electronics allow safe operation on 12 V or 24 V systems. Unlike flush‑mount kits with 1157 bulbs and only 12 V support, the Gen 2 light is truly universal.
Build Quality / Warranty
Every Gen 2 light uses a tempered‑glass lens, anodized‑aluminum body, internal fan, radiator fins and positive‑pressure vents. These components provide durability, efficient heat management and moisture resistance. The light comes with a one‑year warranty, which exceeds the six‑month warranty of many flush‑mount kits. Like all Glass is Class products, it is extremely bright and not SAE/DOT approved, making it ideal for off‑road, show and custom applications.
Warranty: 1-Year Limited Warranty
Designed and validated by Alpha Series Lighting for real-world truck environments.

Frequently Asked Questions
How does the Clear/White variant differ from Clear/Red and Amber/White options?
The Clear/White light pairs a clear tempered‑glass lens with a white LED chip. This produces a pure white beam without any tint, ideal for chrome or clear‑lens builds. The Clear/Red variant uses the same clear lens with a red chip, emitting a vivid red signal, while the Amber/White variant uses an amber lens and white chip, giving a lighter amber hue.
Can I run this light at full brightness continuously?
Yes. The AlphaFit G2 bulb is designed to handle continuous 20 W operation. Its oversized anodized‑aluminum body, internal fan and radiator fins dissipate heat effectively. To run the light at full brightness continuously, connect the yellow wire (high) to your marker circuit and cap the blue wire.
Is the light waterproof and suitable for pressure washing?
Absolutely. The Gen 2 housing features a silicone gasket, anodized‑aluminum base and check‑valve vents, giving it an IP68 rating. You can safely wash your vehicle without water getting inside the light.
Will this light work on 24‑volt trucks and tractors?
Yes. The AlphaFit G2 bulb includes internal circuitry that automatically accommodates 12 V or 24 V systems. Simply wire it according to the pigtail instructions, and it will operate safely on either voltage.
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. Competitor flush‑mount kits may be DOT compliant and come with shorter warranties, but they do not offer the same intensity, cooling and tempered‑glass construction.
Can I switch to a different LED color later?
Yes. The light uses a standard H11 bulb base. You can replace the AlphaFit G2 with another colour or replacement bulb as they become available.
