Abstract: A system of signal lamps for an auto or truck places the lamps where they are visible to the driver of the vehicle, as well as to the drivers of other vehicles. The lamps act as running lights and turn signal lights. The system comprises four omnidirectional, surface-mounted signal lamps. These are mounted in two pairs: an amber front pair and a red rear pair. The front pair is located on that surface of the vehicle which is the front-most upper surface of the vehicle where they are within the view of the driver. These front lamps alert the driver to the lamp condition directly, and also warn other motorists. The rear pair is side-mounted, in places where the driver can see each rear lamp in one of the side-view mirrors. These locations make the lamps highly visible to the driver, because they are visible in regions where the driver habitually looks, and because they are angularly close to the normal view straight ahead.
