The Next Evolution in Glass Marker Lighting Starts Here.
The Red Alpha Series Glass is Class Star Watermelon Light is the ultimate fusion of vintage trucking style and modern LED engineering. Now equipped with our exclusive AlphaFit LED Bulb for Glass is Class Lights, this reimagined marker light delivers powerful illumination, seamless reliability, and refined optics—wrapped in a real glass lens that projects a deep, star-pattern beam.
Whether you’re building out a semi, decking out a show rig, or modding a pickup with real-truck vibes, the Glass is Class series sets the new gold standard in auxiliary lighting.
🔧 What’s New with AlphaFit?
This isn’t just a brighter bulb. It’s a smarter one.
The new AlphaFit 14W H11 LED bulb replaces our old 60W external-fan design, solving common issues like moisture intrusion, fogged lenses, and installation headaches. AlphaFit features:
-
✅ Internal Cooling Fan – No exposed rear fan to collect water or dirt
-
✅ Radiator Fin Heat Sink – Passive cooling fins built into the housing
-
✅ Positive Pressure Performance – Heat and airflow push condensation out through the light’s 4 PTFE vents
-
✅ Compact Profile – Installs cleanly in tight spots like torpedo cab lights and mirror mounts
-
✅ Two-Wire Electrical Connection – Confirm the power, ground and switching arrangement for the actual vehicle circuit
It’s all the power you want—without the bulk or the burnouts.
💡 Why Choose Alpha Series Glass is Class Watermelon Lights?
✅ Real Glass Star Lens
Not plastic. Not “glass-like.” This is the real thing. Tempered glass with radial prisms creates a sharp, glowing starburst beam that diffuses light evenly and looks iconic on any truck.
✅ Optimized Beam Pattern
The AlphaFit LED bulb uses a straight PCB design for a full, even beam with no voids in the center of the pattern—unlike older overpowered bulbs that caused dark zones.
✅ Weatherproof by Design
The updated Glass is Class housing now includes a silicone adhesive seal gasket, making it fully IP68 waterproof. Combined with AlphaFit’s internal fan and our 4-vent G.O.R.E. membrane, keep the seals and vents intact during installation and maintenance.
✅ For Trucks That Show Up and Show Off
Designed for semi-trucks, pickups, custom sleepers, and air cleaner panels, the Red Glass is Class light provides a starburst accent for custom builds when its mounting and wiring match the installation.

🚫 Important Use & Compliance Info
These lights are for show and off-road use only.
They are not SAE/DOT compliant due to their brightness and beam pattern. Even in red, they may be considered a distraction to other drivers. Please check local regulations before use on public roads.
🛠️ Installation & Fitment
This original red Glass Is Class light uses a 12V, two-wire power-and-ground connection and the listed 14W AlphaFit H11 bulb. Compare the mounting opening, rear clearance and wire routing before choosing a cab, mirror, air-cleaner or frame location. A truck model or a matching voltage alone does not confirm the physical fit.

Frequently Asked Questions
Is this the original light or Glass Is Class Gen 2?
This is the original red Glass Is Class assembly, SKU Alpha-Glass-R, with its listed 14W AlphaFit H11 bulb. The discontinuation notice above links to the corresponding Gen 2 replacement. Gen 2 bulb settings should not be applied to this older assembly.
What is included with one light?
One red single-color Glass Is Class light with a pre-installed AlphaFit H11 LED bulb is included. The mounting bracket is sold separately.
What power and wiring does this version use?
This listing specifies 12V, 14W and a two-wire connection: power and ground. It is a single-color version; the separate low/high and dual-color wiring of newer Gen 2 lights is different.
Can I mount it on a pickup or a big rig?
It can be used for a custom show or off-road accent project on a suitable 12V system. Check the actual light opening, bracket, rear clearance and protected wiring route before ordering; vehicle model names do not establish a bolt-on fit.
Can the bulb be replaced later?
Yes. This version uses a replaceable AlphaFit H11 bulb for Glass Is Class lights. Match the original assembly and replacement-bulb specifications; an H11 label alone does not confirm cooling clearance or a suitable replacement wattage.
Is it an approved road-going marker replacement?
The existing product designation is show and off-road use only, not SAE/DOT compliant. Choose the light for that stated use and check the requirements for its installation location.
What gives this light its starburst appearance?
The original assembly uses a real glass star-pattern lens. Choose the output color and mounting position around the intended accent effect; the lens pattern does not establish forward-road-light performance.
