J.W. Speaker’s Models 538 and 539 LED strobe safety warning lights offer an advanced lighting solution that merges high-visibility signaling with critical operator feedback in one compact, low-profile design. Now enhanced with the addition of red/green indicator functionality, these lights are engineered to support safety protocols in demanding environments such as agriculture, construction, mining, material handling, industrial operations, railroad, specialty vehicles, truck, and bus applications. The new indicator light, integrated within the Model 539 flange mount and Model 538 pipe mount configurations, alerts operators with a dual-color system—displaying red to indicate an unbuckled seatbelt and green when it is securely fastened. This intuitive signaling helps reduce operational risks and ensures quick visual compliance checks.
Built for rugged use, the Models 538 and 539 feature impact-resistant acrylic lenses that resist scratches and scuffs, enhancing durability even in high-impact work zones. Their polycarbonate housing adds further strength without compromising on weight or form factor. These models utilize a solid optic design with a single LED source, enabling the use of multiple LED colors—amber, red, green, blue, and white—without relying on colored lenses. This not only improves light output and visibility but also results in a cleaner, sleeker visual appearance, which is critical for maintaining a professional, uncluttered lighting system on industrial or commercial vehicles.
These strobe and indicator lights operate over a wide voltage range of 12 to 80 VDC, making them adaptable to a broad variety of vehicles and machinery. Their flange mount (Model 539) and pipe mount (Model 538) options allow for flexible installation on both flat surfaces and pipe-style configurations, ensuring a secure fit in virtually any location. The frosted lens used for the indicator version provides clear visibility without creating unnecessary glare, supporting both day and night operation.
Designed and manufactured with compliance and longevity in mind, these models meet Buy America requirements and represent a modern update over their predecessor, which was redesigned in 2017. For legacy product needs, customers can reach out to their J.W. Speaker representative. With their sleek, durable design, multiple color options, and intelligent safety feedback, the 538 and 539 series lights represent the next generation of industrial-grade strobe and indicator lighting for operators who demand both performance and accountability on the job site.
