The lighting system of a motor vehicle consists of lighting and signalling devices mounted or integrated to the front, sides, rear, and in some cases the top of the vehicle. The purpose of this system is to provideilluminationfor the driver to operate the vehicle safely after dark, to increase theconspicuityof the vehicle, and to display informati

on about the vehicle`s presence, position, size, direction of travel, and driver`s intentions regarding direction and speed of travel. Driving lamp" is a term deriving from the early days of night time driving, when it was relatively rare to encounter an opposing vehicle. Only on those occasions when opposing drivers passed each other would the dipped or "passing" beam be used. The full beam was therefore known as thedriving beam. Turn signals are required to blink on and off, or "flash", at a steady rate of between 60 and 120 blinks per minute (Although some operate slower than this). International regulations require that all turn signals activated at the same time (i. e. , all right signals or all left signals) flash in simultaneous phase with one another;North American regulations also require simultaneous operation, but permit side markers wired for side turn signal functionality to flash in opposite-phase. Worldwide regulations stipulate an audiovisualtelltalewhen the turn signals are activated; this usually takes the form of one combined or separate left and right green indicator lights on the vehicle`s instrument cluster, and a cyclical "tick-tock" noise generated electromechanically or electronically. It is also required thataudioand/orvisualwarning be provided to the vehicle operator in the event of a turn signal`s failure to light. This warning is usually provided by a much faster- or slower-than-normal flash...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
