car alarm

A car alarm is an electronic device installed in a vehicle in an attempt to discourage theft of the vehicle itself, its contents, or both. Car alarms work by emitting high-volume sound (often a vehicle-mounted siren, klaxon, pre-recorded verbal warning, the vehicle's own horn, or a combination of these) when the conditions necessary for triggering it are met. Such alarms may also cause the vehicle's headlights to flash, may notify the car's owner of the incident via a paging system, and may interrupt one or more electrical circuits necessary for the car to start. Although inexpensive to acquire and install, the effectiveness of such devices in deterring vehicle burglary or theft when their only effect is to emit sound appears to be negligible.

    A series of unfortunate events: alarm, then strange yellow warning light

    Had a strange one with Leo the Goth MG4 today, and I thought I'd share the experience here in case the MG4 hive mind has any ideas. From the beginning: We were going into the village. I climbed in, and all the usual lights came on, and I put my foot on the brake. I tried putting Leo into...

I unlocked the car, shut the door properly and locked up. All fine. I've now received a text message saying 'the abnormal invasion into your vehicle has...

    Turning off the car-alarm for travel on ferries

    I use car-ferries relatively often, and some operators request that people deactivate the theft-alarm because the vibration (on high-speed ferries) and wave motion (on traditional ferries) can trigger the alarms continually, flattening the car's 12V batteries, and making the car-deck(s) rather...
