Stoplight signaling equipment for a motor vehicle comprising a normally open inertia switch electrical contacts of which are connected in a circuit controlling illumination of a warning light and are closed by movement of an inertia element in the switch caused by inertia forces upon bodily acceleration of the switch. The switch is preferably mounted on throttle linkage of the vehicle to be moved bodily upon actuation of that linkage so that on sudden release of the throttle the switch is accelerated bodily to cause closure of contacts whereby light is illuminated even before vehicle brake is applied. |
