Stoplight Indicators

Name: StoplightRG_01.sym, StoplightRG_02.sym, StoplightRYG_01.sym, StoplightRYG_02.sym

Custom Properties: GreenTag, RedTag, YellowTag

Description: This symbol set has 4 different indicators, 2 with Red and Green only and 2 with the addition of a yellow “Lamp”. Each lamp can be independently controlled so it is up to the developer to set the tags so only one color is on at a time, or if they choose, multiple lamps can be lit simultaneously. Great for digital signage, production monitoring (ANDON), or pass/fail test systems.


  1. These symbols use the enhanced “Visibility” animation.

  2. These symbols were created primarily for use on a PC running on a desktop or server operating system, but with some slight modifications, can be made to look great on Embedded or even Mobile Access clients.

Ideas for improvement:

    1. Remove the gradients and visibility (transparency) for use on Embedded and/or Mobile access clients.

    2. Create a horizontal version.

Here’s how to use this symbol:

Unzip and copy the .sym files into your Symbol folder of where InduSoft Web Studio is installed. This is usually “C:\Program Files (x86)\InduSoft Web Studio v7.1\Symbol” or similar. Either create a new folder or copy it into an existing one, such as “Indicators”.
