OBDResource TL123 Automotive Timing Light – 12V/24V Ignition Timing Gun with Adjustable Advance, LED Display & High-Visibility Strobe Diagnostic Tool

The OBDResource TL123 Automotive Timing Light is a professional ignition diagnostic tool engineered for accurate engine timing verification across both 12V and 24V vehicle systems. Designed for technicians, workshops, and performance tuners, this timing gun delivers precise ignition timing analysis to help optimize engine performance, improve fuel efficiency, and reduce emissions.

Equipped with a high-intensity xenon strobe tube, the TL123 produces bright, stable flashes that clearly illuminate timing marks even at high engine speeds. Unlike standard LED timing lights that lose brightness during rapid flashing, xenon technology maintains consistent visibility across all RPM ranges, ensuring reliable readings during real diagnostic conditions.

The built-in display and adjustable timing advance function allow technicians to fine-tune ignition timing quickly and accurately. With its inductive pickup clamp, the device reads ignition signals safely without damaging wiring, making setup fast and convenient for both professional and field use.

Supporting both passenger vehicles and heavy-duty systems, the TL123 is suitable for gasoline engines in cars, trucks, SUVs, and commercial equipment. Its rugged housing and professional-grade components ensure durability during frequent workshop use.
