Truck-Lite 329D Signal-Stat Back-Up Alarm Bulb – 87 dB Single Sound, 20W Halogen, Wedge Base, 12V

Upgrade your vehicle’s reverse visibility and safety footprint simultaneously with the Truck-Lite 329D Signal-Stat Back-Up Alarm/Bulb. This innovative, dual-action safety device seamlessly combines a high-output halogen reverse lamp with a built-in audible alert system, offering a practical, cost-effective way to add an audible alarm to passenger vehicles, vans, RVs, and light commercial trucks.

The Truck-Lite 329D features a powerful 20-watt halogen bulb that delivers a crisp, bright light output to illuminate hazards behind your vehicle while backing up. Simultaneously, the integrated solid-state alarm emits a clear, steady 87 dB "beep-beep" warning sound to alert pedestrians, cyclists, and other drivers that your vehicle is in reverse gear.

Forget about routing complex wiring harnesses, drilling into your chassis, or splicing factory wires. The Signal-Stat 329D is engineered for instant installation—it goes in as easily as replacing a standard burned-out reverse bulb. Outfitted with a standard industry wedge base connection, it drops directly into your vehicle’s existing factory light socket.

Built to handle the vibration and daily abuse of over-the-road travel, the 329D features a durable aluminum housing that efficiently dissipates heat away from the halogen element. Packaged in a high-visibility retail display format, it is the perfect proactive safety upgrade for owner-operators, delivery vans, school buses, and light duty fleet vehicles.

Note: These localized combination safety bulbs are excellent secondary safety additions but do not meet specific OSHA or SAE J994 rigid requirements for heavy commercial vehicle primary backup alarms.
