# 2.1.12 Signal

A signal is created by selecting Create Signal from either the Add menu Section 3.3.1 or from the hotbar. Use the mouse to select a location (left button) and then dragging (left button down) the signal to set its orientation. Once the left button is released, a Create/Edit Signal dialog box is displayed, and you can fill in the signal's properties: name, fine tune the location and orientation, number of heads, and the aspects.

The create/edit signal dialog has spaces for the name of the signal, its location and orientation, the number of heads (1, 2, or 3), and a list of aspects. Each aspect has a name and a script. The name could be a rule book name (Clear, Aproach, Stop, etc.) or the actual color(s) displayed (green, yellow, red, etc.). The script is just some information for the layout control software to actually effect the display of the aspect -- this could be the LCC event id to trigger the aspect or it could be a code snippet that causes the aspect to be displayed.
