Frontier isn’t just a name—it’s a declaration. Born from the legacy of Dialight’s trusted traffic signal designs and reimagined by LEOTEK’s innovation-driven R&D and product management teams, Frontier stands as a symbol of reliability, evolution, and regional adaptation.


The EV Series 12-inch LED railroad grade crossing signal module provides a red crossing warning indication with low-wattage options and red or white side lights. It is intended for compatible rail-crossing signal heads and controller systems, rather than transit bar or triangle indications.
The EV data sheet lists several supply configurations and model-specific ranges. It shows 8–20 Vdc / 8–16 Vac for the main listed operating range and a separate 8–14 Vdc / 8–16 Vac entry for the unregulated TSL-12RCS-EVW-U1. The Resources folder labels use different nominal ranges, so confirm the exact power-supply model and electrical drawing before ordering.
