The study focused on the design and fabrication of a Vehicular Signal Circuit Trainer to serve as an instructional device for automotive technology students at Palompon Institute of Technology. The trainer was developed to provide a hands-on, interactive platform for learning the principles, operation, wiring installation, and troubleshooting of automotive turn signal and hazard lighting systems. Fault simulation tests demonstrated that the trainer reliably replicated common system failures, including blown fuses, broken wires, loose contacts, corroded terminals, short circuits, component failures, and low battery voltage. Evaluation by five instructors and thirty-eight students assessed design, performance, and safety using a structured five-point Likert scale. Results indicated high acceptability across all dimensions, with design receiving the highest mean score (4.76), followed by performance (4.73) and safety (4.70), yielding an overall grand mean of 4.74. Participants consistently rated the trainer as effective, reliable, and safe, confirming its suitability as a classroom demonstration and practical laboratory teaching tool. These findings suggest that the trainer system enhances student competence, supports instructional innovation, and provides a robust platform for experiential learning in vehicular signaling systems.
