The present invention relates to an improved wireless communications system capable of efficiently transmitting smaller-sized data packets that are frequently delivered to mobile nodes on the communications system, such as voice communications. The vehicle brake assembly brake shoe mounting system includes a brake mounting member and a pair of brake shoes slidably supported relative to the brake mounting member. The switching circuit includes several switches controlled by a digital counter for turning off portions of the circuit which are not in use. The first spacer overlies the hard mask layer conformal to a sidewall of the logic gate structure. Once activated, the lights flash in the direction of oncoming traffic, and emanate directly from the roadway, to warn drivers of approaching vehicles that a stop may be required at the intersection, and that caution should be exercised.
