FIND YOUR LIGHTS
Compare lights, kits and replacement parts by family below.
Check the exact assembly, voltage, wiring, mounting parts and included quantity. Match the light’s opening, fixing pattern and rear clearance; lens material alone does not establish fit.

Shop glass watermelon lights for semi trucks, pickups and custom builds. Compare complete lights and kits by family, then find the matching bulbs, lenses and service parts below.
This collection brings several real-glass light systems together. Check the exact assembly, voltage, wiring, mounting parts and included quantity before ordering.
MODULAR GLASS LIGHTS
Compare the listed Gen 2 single-colour and Duo combinations. Match lens colour and LED colour, and check the exact light’s function and wiring. Gen 2 uses its matching AlphaFit system; do not assume parts interchange with the original generation.
STEADY • ROTATING SIMULATION • STROBE
Browse Alpha 360 glass beacons by colour combination. These specialty lights offer steady, rotating-simulation and strobe modes and are not Class 1 warning lights. Check the exact application before choosing.
COMPARE THE EXACT KIT
Compare UltraBurst glass flush-mount kits and their listed LED/lens combinations. Similar product names can describe different bulb or kit versions; open the exact listing to confirm the included parts.
DUAL-COLOUR OPTIONS
Compare the 360-degree bulb and 4 LED glass kits by their listed colour pair. Review the bulb type, wiring and kit contents; lens colour alone does not describe the emitted light.
2 LED • 4 LED • DUAL FUNCTION
Browse 2 LED, 4 LED and other LED glass-light kits, including dual-function options. Check the exact voltage, light function, wiring and supplied hardware on the product page.
LENS & MOUNTING OPTIONS
Compare these glass flush-mount kits by lens colour. Confirm what the selected kit includes and whether a bulb or other mounting parts are needed separately.
ASSEMBLIES AND HOUSINGS
Compare complete light listings with housing-and-lens listings. A housing with two glass lenses is not automatically a complete wired light; check the exact bulb, wiring and included-parts details.
APPLICATION-SPECIFIC PARTS
Browse the 3157 upfitter, Grakon-style cab conversion and 3/4-inch Mini-light kits. These are different installation systems. Match the exact application, opening, base and included components before ordering.
MATCH THE BULB SYSTEM
Find AlphaFit Gen 2 and 1157 UltraBurst bulbs together. Match the required base, generation, voltage and wire functions; the shared watermelon-light name does not make these bulbs interchangeable.
REPLACEMENT & MAINTENANCE
Browse glass lens listings, replacement glass, gaskets and venting patches. Check whether the item is a lens, housing or service part, the compatible light family and the supplied quantity.

Start with the complete light family and intended mounting location. Then compare the exact voltage, wiring, light function, dimensions, LED colour, lens colour and included quantity. Lens material alone does not establish compatibility.
Not always. This collection includes complete light listings, kits, replacement bulbs, lenses and service parts. Check the exact product’s included-parts list before ordering additional components.
Do not assume they interchange. Gen 2 uses a modular AlphaFit bulb and matching real-glass housing. Match the generation and product-specific compatibility information.
No. Match the light’s opening, fixing pattern, depth and clearance to the bracket. Use the bracket collection and mounting guide to plan the installation.
No. Lens colour and LED colour are separate specifications. Compare both in the selected listing, including each colour and wire function on dual-colour products.
Alpha 360 is a specialty glass-light family with steady, rotating-simulation and strobe modes. It is not a Class 1 warning light; check the intended use and exact product details.
