LD Series

LD Series Traffic Signal Module – Bi-Modal Arrow

Name: LD Bi-Modal Traffic Signal Arrow | LEOTEK
Brand: LEOTEK

The LD Series 12-inch bi-modal LED traffic signal arrow supports two specified indication combinations: Yellow-to-Green and Yellow-to-Yellow. It is intended for compatible signal heads and controller wiring where a paired arrow display is required, rather than a conventional single-color arrow module.

The LD data sheet identifies TSL-12BM-LD-A1 for Yellow/Green and TSL-12YYBM-LD-A1 for Yellow/Yellow operation at 80–135 Vac. Match the requested sequence, termination and controller behavior to the exact order code before specifying.
