Reed switches in Defective lamp detection

Reed switches in Defective lamp detection
Automobile Lamp

Automobiles these days provide a wide range of information ranging from door and window position, wind screen viper fluid level, whether a tail lamp has failed, the positions of the engine hood and trunk and also whether the fuel cap has been closed fully. Reed sensors are the only devices that are hermetically sealed and completely safe to use even inside fuel tanks and they are molded, which means they can withstand higher shock and vibration limits, as well. Reed Sensors also have the added advantage of withstanding temperatures of up to 150°C without much change in actuating distance when the right magnets are used. Tail lamps and parking lamps are very vital elements of an automobile and any failure could cause accidents. Reed relays, by virtue of their small size and high life, find an important role in these applications. A reed relay and a resistor are connected across the lamp and when the lamp fuses, the reed relay energizes and the output is used to trigger an alarm on the dash board.
