Over the years, tree large product families have been developed in the respect of the most severe standards, requested by our customers, neon xenon and led type. OBSTA lights are designed in the respect of the latest international standards that are ICAO and FAA. They constitute a complete range low intensity or L-810, medium intensity or L-865/L-864 and also high intensity, ideal for broadcasting towers, telecom mast, transmission lines, stacks and wind turbines.

Cold neon discharge lights,
pure cold neon discharge 5 and 13 turns OBSTA® HI STI & STI,
33 & 49 turns BALISOR® (conductor warning lights) red fixed obstruction lights.

Led NAVILITE® red fixed obstruction lights (low intensity and L-810) since 2003 The NAVILITE series is dedicated to night only obstruction lights especially for telecom mast, buildings close to airports and all kind of obstacle below 45 meters high. Completely molded with 64 leds divided in 16 independent led circuits, they are ideal for all kind of obstacle
