Traffic Signal – Go/No Go

Using the Signals

These traffic lights are a popular device to illustrate a go/no go/further study concept in decision making. There are two series that you can use for this concept: Concepts 092 (CN092) and Concepts 100 (CN100). You may want to review both series (links to each at bottom of this article) to make sure you have chosen the most suitable signals for your message.

CN092: contains red/yellow/green artist-drawn versions that cannot be edited. They need to be used as is, but they can be animated (see below in Animation section).

CN100: contains editable and somewhat editable versions and multiple layouts, which are graphics are ready for immediate use or may be easily modified for other uses. There are two types of bulbs:

  • There is a set that is beveled and not modifiable in PowerPoint 2003. They are tintable in PowerPoint 2007.
  • There are variations that have been fully formatted with color and line colors. There are also variations that are without formatting so you can apply your own. The "hanging" signals can be stacked into any number configuration. These may be used individually as icons next to text or they can be used as a group.

Customizing the Signals

Adjust size

If you want to change the size/shape of a signal, be sure to group it and resize the entire group. Once resized, ungroup to proceed with other customizations.To rescale, hold the shift key down as you resize.

The CN092 variations are not equally sized graphics because there is a glow emanating from the lit bulbs. This makes aligning the signals a more manual process. We suggest using guidelines to help you size and align the signals if you use them as animated overlays. We've also provided these as a slide in the download to save you the trouble.

Color variations

Individual elements in the CN092 signals cannot be colored, but the graphic can be tinted. This is not a great formatting choice, however, since the signals rely on specific colors to deliver their messages. The downloads are standard red/yellow/green colors.

CN100 has both editable and noneditable elements available for use. And even the noneditable graphics have been assembled in parts so that the light colors can be changed. The downloads have been preformatted with realistic colors. There is also a page of signals that have not been colored in case you wish to just color the lines and use it as a tone-on-tone illustration.

3D variations

These graphics are drawn in 3D, so you should not apply this effect.


Don't add shadows to these graphics.

Gradients, patterns, and pictures

Gradients have been applied to the signals in some cases. This is a good effect to help make the graphic appear more realistic.


In reality, the signals are not movable objects, so they shouldn't be animated to zip around the slide. A good animation scheme might be to select the "bulb" and apply an "emphasis" animation which changes the color of the bulb. For example, a further-study idea can change to a go or no-go idea by making the yellow change to red or green. Try this if it is appropriate to your message.

Both CN092 and CN100 have animated examples available for download that show possible animation schemed, which might be helpful.
