BTS Lighting Alpha Series Glass is Class LED Star Watermelon Light; Amber (Universal; Some Adaptation May Be Required)

The Next Evolution in Glass Marker Lighting Starts Here.
The Amber 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
✅ Zero CANBUS Interference – Trouble-free performance with no extra circuitry

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, moisture doesn’t stand a chance.

✅ For Trucks That Show Up and Show Off
Designed for semi-trucks, pickups, custom sleepers, and air cleaner panels, the Amber Glass is Class light installs easily and performs reliably on everything from heavy-haulers to slammed show builds.

🚫 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 amber, they may be considered a distraction to other drivers. Please check local regulations before use on public roads.

🛠️ Installation & Fitment
Glass is Class lights are plug-and-play with any standard 12V setup. The updated compact AlphaFit bulb allows installation in tight cab spaces, behind air cleaners, in mirror mounts, and other tight-frame brackets—places where the old 60W bulb wouldn’t fit.

FAQs
Q: Is this the same as the old 60W light?
No. The new AlphaFit LED runs cooler, fits better, and lasts longer. While it’s less raw wattage, its beam is sharper and more evenly lit.

Q: Can I use this on a pickup truck or 12V system?
Absolutely. These are 12V compatible and commonly used in custom pickup builds, bed racks, grilles, and cab lights.

Q: Is this a DOT-legal marker light?
No. This light is too bright and not SAE/DOT approved for road use. We recommend using it for off-road or show truck builds only.

Q: Can I replace the bulb later?
Yes! The AlphaFit bulb is a standard H11 base and is available separately on our site.

Q: Does this include the mounting bracket?
No. Brackets are sold separately. Check out our full selection of Watermelon Light Mounting Brackets for install options.
