The Putco YellowJacket LED rooftop strobe light bar is a compact, high-intensity LED warning light designed for work trucks, fleet vehicles, and safety-focused applications where visibility is critical. Unlike traditional full-size rooftop strobe light bars, the YellowJacket delivers professional-grade warning output in a compact 12-inch housing by using advanced optical technology instead of relying on size alone. Built for real-world conditions, it combines high-intensity TIR LED performance, dual-color amber and white output, 33 selectable strobe patterns, IP69K waterproof construction, and a wide operating voltage range of 12 to 54 volts DC. This makes it a versatile LED warning light solution for pickup trucks, commercial vehicles, and heavy equipment.

How the YellowJacket Strobe Light Bar Works

Advanced Compound Projection Optics

At the core of the YellowJacket is a compound projection lens system that controls and shapes light output. Instead of simply emitting light outward like standard LED strobe lights, this system redirects light at precise angles, combining wide-angle coverage with focused intensity. It maintains consistent brightness across viewing angles to create a 360-degree visible warning signal. This allows the YellowJacket to cut through bright daylight, rain, fog, and snow while delivering strong visibility from all directions. This approach focuses on optical efficiency rather than size, which is why a compact light bar can perform at a high level.

Dual-Color Output and Flash Patterns

The YellowJacket features amber and white LED strobe output for flexible visibility configurations. It includes 33 programmable flash patterns with memory recall, so the light returns to your last selected pattern. Users can run amber only, white only, or a combination of both colors, depending on the application. This flexibility supports work zone safety, fleet visibility, roadside assistance, and emergency response.

Tap-N-Sync Programming System

The YellowJacket uses Putco’s Tap-N-Sync system for programming and control. Patterns can be changed using a simple ground tap during installation or after installation. No remote is required to operate the light. For added convenience, the Putco Luminix Tap-N-Sync Programmable Wireless Remote can be added as an optional upgrade. This gives users full control without complex wiring or external controllers.

Mounting Options and Installation Flexibility

Installation requirements vary depending on the mounting method, allowing users to choose between permanent and no-drill setups.

Standard Mounting Options

The YellowJacket is designed to work across multiple mounting setups, depending on the vehicle and application. It includes a universal mounting bracket for hard mounting, which may require drilling depending on the mounting surface and installation method. It also supports magnetic mounts for temporary installation, headache rack mounting systems, BackRack setups, and T-slot compatible racks. This allows the light to be used across a wide range of vehicles and equipment.

No-Drill Mounting Option

For a clean, factory-style install, the YellowJacket can be paired with a vehicle-specific third brake light mounting bracket. Installation varies depending on the mounting method. When using a vehicle-specific third brake light bracket, the light mounts to factory locations with no cutting or drilling required. It is secured with automotive-grade adhesive for added stability and is designed to maintain rear camera visibility. This is one of the easiest and most secure installation methods available for rooftop strobe lighting.

Hornet Bracket Compatibility

The YellowJacket is compatible with existing Hornet mounting brackets. This allows users to reuse installed hardware and upgrade or change lighting setups without replacing mounts. It is especially useful for fleet vehicles or users already running Hornet systems.

Built for Harsh Environments and Daily Use

IP69K Waterproof and Weatherproof Construction

The YellowJacket is fully sealed and IP69K rated, providing complete protection against dust, water, and high-pressure washdowns. It is designed to handle extreme weather conditions including rain, snow, mud, and jobsite exposure.

Thermal Management for Consistent Performance

The aluminum base includes heat-dissipating fins that help regulate temperature during operation. This prevents overheating and allows the light to maintain consistent performance during extended use.

All-Season Reliability

The YellowJacket operates in temperatures ranging from negative 40 degrees Fahrenheit to 185 degrees Fahrenheit. The polycarbonate lens is engineered to resist yellowing, fading, and wear over time, ensuring long-term clarity and performance. The light is also backed by a 10-year warranty, reinforcing its durability for long-term use in demanding environments.

Who It’s Designed For

Built for Visibility and Safety

The YellowJacket is designed for users who need reliable, high-visibility warning lighting without the bulk of a full-size rooftop light bar.

Ideal Applications

This light is well-suited for construction and jobsite trucks, utility and service fleets, tow trucks and roadside assistance vehicles, snowplows and municipal vehicles, agricultural and industrial equipment, forklifts, trailers, and off-road vehicles.

Designed for Real-World Use

The YellowJacket is a practical solution for daily drivers, fleet managers, and professionals working in low-visibility environments. Its compact size, flexible mounting options, and durable construction make it adaptable to a wide range of use cases.

Why It Works

The YellowJacket takes a different approach than traditional rooftop strobe light bars. Instead of relying on size, it focuses on optical efficiency, mounting flexibility, and durability. Its compound projection lens system allows it to deliver strong visibility in a compact form. Its multiple mounting options make installation adaptable to different vehicles and setups. Its sealed construction and thermal management ensure long-term reliability. This combination makes it a strong choice for users who need dependable visibility in demanding conditions.
