Restrooms at public places like Airports, Malls, railway stations, multiplexes & stadiums have high foot traffic and long ques. Pushing the cubicle door to see if it is occupied or vacant, cubicles going unused while people que up behind a few cubicles, entering a restroom and not knowing which cubicle to go for can be a worrisome experience. T-Line occupancy-vacancy Indicator Lights optimize stall usage, reduce the waiting time and increase the overall restroom efficiency and user comfort. The indicator lights fixed on the top of the front panel indicate the occupancy & vacancy status of the cubicle with red green led light, visible to the visitors as they enter the toilet block, so they can choose which stall to go for. It considerably shortens waiting lines, toilet crowding and enhances the user ease and comfort.
