Because at the start and stop of motor it will take high current on starting of motor.
Turning on the lights of a car will increase the electrical load on the battery, but it will not significantly impact the fuel consumption or gas mileage of the vehicle. The amount of gasoline burned by the engine is not directly affected by the operation of the lights.
If the dome lights or lights under the dash don't turn off after exiting the car, you can try closing all doors properly and ensuring the parking brake is engaged. If they still do not turn off, there may be a faulty door switch or wiring issue that needs to be addressed by a mechanic. You can also try manually turning off the lights using the light switch if applicable.
Energy can be turned into mass through the process of pair production, where a high-energy photon creates a particle-antiparticle pair. An example of turning energy into mass is when a gamma-ray photon interacts with an atomic nucleus, leading to the production of an electron-positron pair.
Of course not. When the light is on, it uses energy; when it is off, it doesn't, 'tis as simple as that. I have heard certain rumors that turning it on will use (for example) the equivalent of two hours of just being normally on. Since turning the light on takes but a few seconds, a simple calculation shows that this would produce enough current to trip any standard fuse or circuit-breaker. What's more, I personally turned a one of those lights (40 Watts) on and off 40 times in a row, and checked the energy usage. According to the above mentioned rumor, this would have to use about 2 kWh; the meter didn't advance a single kWh. Unfortunately, I don't have the equipment to do finer measurements, but it just doesn't make sense.
A TV typically uses more power if it's left on for an hour than if it's turned off and then back on. When a TV is on, it is actively using electricity to display images and produce sound. Turning it off reduces power consumption, but the initial surge of power when turning it back on should be considered.
What causes the dashboard light to stay on after your car has been turned off? 1994 Buick Century.
Bad relay
The switch is probably bad or you aren't turning the knob all the way off.
there is a bad ground somewhere
There are various ways to tell night time in Pokémon SoulSilver which would include Street Signs turning on, buildings turning on their inside lights so that you see their lights from the outside and the Magnet Train having turned its inside lights on so you can see the inside lights from the outside view.
Simply because of the extra drain on the circuit. When a high-current device like a washing machine is switched on - it creates a temporary 'dip' in the power supply around the building. The mains supply compensates for the extra load on the circuit fairly quickly - but it's still noticeable by the dim lights.
The driving lights on a Volvo xc90 are turned off by turning the knob on the left side of the steering column. Driving lights are used to notify other driver's of the vehicle's presence.
Answer You might want to check your flasher relay which is under the dash.
try turning off your headlights
A mis-wiring or short circuit somewhere between the controls, fusebox and lights.
It's a relay. Which one it depends... I would start from testing headlights relay.
Look for a knob on the panel which dims the dash lights. It may be turned all the way down.
