Product Overview
Most clear‑lens watermelon lights use dozens of small diodes behind a polycarbonate lens and only run on 12 V. For instance, a standard clear/amber light from Trux Accessories uses 19 diodes, a clear polycarbonate lens, and operates at 12 V with an IP67 rating and 3‑year warranty. The Star Burst clear amber lights are similar: they have a star‑burst pattern, 19 diodes, a clear lens, polycarbonate construction and are DOT compliant. These lights are adequate for basic marker duties but lack the intense output, dual‑voltage flexibility and weatherproofing needed for high‑end builds.
The Gen 2 Clear/Amber Glass is Class light solves these shortcomings by combining a true glass star lens, a high‑output AlphaFit G2 LED bulb, and dual‑function wiring. It offers both 15 W marker and 20 W signal modes, operates on 12 V or 24 V, and features advanced cooling and positive‑pressure venting for condensation‑free performance. Whether you’re outfitting a show truck or a heavy hauler, the Gen 2 light delivers brighter, cleaner amber illumination and unmatched durability.
Key Features & Benefits
Clear Lens with Amber LED Chip – Crisp Amber Glow
The clear tempered‑glass lens lets the amber LED chip shine through without the tint of a colored lens, resulting in a lighter, more vivid amber hue. The radial prisms in the star‑burst lens amplify and diffuse the light into a wide, sharp beam with no dark voids—a significant upgrade over the multi‑diode patterns used in typical clear/amber lights.
Dual‑Function AlphaFit G2 LED Bulb (Marker & Signal)
At the heart of the Gen 2 light is the AlphaFit G2 H11‑base bulb. Its three‑wire design offers both a 15 W low‑power marker mode and a 20 W high‑power signal mode, giving you the versatility of a marker/signal combo or constant full‑brightness operation. In contrast, competitor lights simply switch between diode banks and are limited to 12 V. The G2’s 12/24‑V capability, combined with its internal electronics, ensures consistent performance on any rig.
Advanced Heat Dissipation & Positive‑Pressure Cooling
The AlphaFit G2 uses the same multi‑stage cooling system that made the original AlphaFit bulbs famous: a passive radiator‑fin heat sink and an internal cooling fan work together to pull heat away from the LED chip. The enlarged anodized‑aluminum body acts as a thermal mass, while four check‑valve vents create positive pressure, pushing moisture out of the housing and preventing fogging. This design allows you to run the light at full power continuously without overheating.
Real Tempered‑Glass Star Lens & Optimized Beam Pattern
Rather than using resin or plastic, the Gen 2 features a tempered‑glass lens that’s scratch‑resistant and built to last. The star‑burst pattern projects a wide, even beam, and the straight PCB design of the AlphaFit bulb eliminates dark spots. Competitor lights rely on clear polycarbonate lenses that can yellow or crack over time; our glass lens retains its clarity for years.
IP68 Weatherproof & Anodized Aluminum Housing
The housing uses a silicone gasket, anodized‑aluminum base and check‑valve vents to achieve an IP68 rating, keeping out dust and water even under prolonged submersion. Most clear/amber lights are rated IP67 and use a plastic bezel—adequate for basic road use but not for heavy washdowns or harsh weather. The Gen 2 light is built to handle anything from rain to high‑pressure washes.
Universal Fit & 12/24‑Volt Compatibility
The AlphaFit G2 bulb uses a standard H11 base and comes with a color‑coded three‑wire pigtail. It’s plug‑and‑play on both 12‑volt and 24‑volt systems, eliminating the need for voltage converters. This wide voltage range and slim form factor make installation easy in cab lights, air cleaner mounts, mirror brackets and other tight locations.
New Color Options & Flexible Customization
Beyond the clear/amber variant, Gen 2 Glass is Class lights are available in Clear/White, Clear/Red, Amber/Amber, Amber/White, Red/Red and Red/White. Each combination lets you tailor the look and beam color to your build—whether you want the darkest amber, a bright clear lens or a bold red accent.
Performance / Compatibility / Use-Case
The Gen 2 clear/amber light is designed for maximum brightness and versatility. Traditional clear/amber watermelon lights use 19 small diodes and run at a low amperage on 12 V. The AlphaFit G2’s 20 W high‑power mode produces an intense star‑burst beam that rivals auxiliary spot lights, while the 15 W marker mode provides a perfect accent. Because the bulb supports 24 V as well as 12 V, the light can be used on semis, agricultural equipment and off‑road vehicles without resistors. Positive‑pressure venting means the housing stays condensation‑free even in humid or cold climates, making this light ideal for show rigs, daily drivers and heavy‑duty applications.
Installation / Fitment / Technical Details
Installation is straightforward: use the standard studs on your watermelon‑light bracket (bracket sold separately) and wire the three‑wire pigtail. Connect the black wire to ground, the blue wire to your marker/running light circuit (15 W) and the yellow wire to your signal/brake circuit (20 W). To run the light at full brightness constantly, tie the yellow wire into your marker circuit and cap the blue lead. The light draws 15 W on low mode, 20 W on high mode and is safe on both 12‑V and 24‑V systems. The slim profile fits easily behind air cleaners and mirror mounts and uses a standard H11 base for future bulb replacements.
Build Quality / Warranty
Each Gen 2 light is assembled with a tempered‑glass lens, anodized‑aluminum housing, internal fan, radiator fins and positive‑pressure vents. These features combine to deliver a reliable, long‑life light that resists moisture and corrosion. The light comes with a one‑year warranty, exceeding the 3‑month or 6‑month warranties seen on some aftermarket lights and matching the best warranties on competitor models. Note: like all Glass is Class lights, this product is extremely bright and not SAE/DOT approved for on‑road use.

Frequently Asked Questions
How does the clear/amber variant differ from amber/amber and amber/white?
The clear/amber light uses a clear tempered‑glass lens with an amber LED chip, producing a bright, clean amber hue. The amber/amber variant uses an amber lens and amber chip for the darkest amber possible, while the amber/white variant pairs an amber lens with a white chip for a lighter amber output. All three share the same AlphaFit G2 bulb, dual‑function wiring and IP68 construction.
Will the clear lens yellow or crack over time like plastic lenses?
No. The lens on this light is made from tempered glass, which is scratch‑resistant and does not yellow or haze like polycarbonate. Competitor clear/amber lights often use plastic lenses that can degrade over time; our glass lens retains clarity for years.
Can I use this light on a 24‑volt truck or tractor?
Yes. The AlphaFit G2 bulb supports both 12 V and 24 V systems. Simply wire it according to the included instructions and it will operate safely at either voltage. Competitor clear/amber lights are typically limited to 12 V.
Is the light waterproof? Can I wash my truck with it installed?
Yes. The Gen 2 housing uses a silicone gasket, anodized‑aluminum base and check‑valve vents to achieve an IP68 rating. This means it is dust‑tight and capable of enduring water submersion. You can wash your truck and even pressure‑wash around the light without fear of moisture intrusion.
Are these lights street‑legal?
No. While competitor clear/amber lights may be DOT compliant, the Gen 2 Glass is Class lights are intended for off‑road and show use only. They are extremely bright and do not conform to SAE/DOT standards.
How do I replace the bulb or change colors later?
The AlphaFit G2 bulb uses a standard H11 base, so replacement bulbs are easy to swap. Simply remove the old bulb, insert the new one and reconnect the three‑wire harness. Replacement bulbs in various colors will be available separately.
