An emergency light switch uses a relay. A relay has an 5 terminals. The firs two terminals are connected to a flowing current (current flows when there is a normal electricity) The next 3 terminals are the common, the normally on, and normally off.
One of the battery terminal is connected to the common, and the other one terminal of the battery is connected to one terminal of the light bulb(which has two terminals) then the other terminal of the light bulb is connected to the normally on terminal of the relay. When current flows to the first two mentioned terminals of the relay, the circuit of the battery and light is cut off or not connected. But when the current is off, this will switch on the normally-on terminal thus current will flow from the battery to the light bulb, that will shed light. ;) on an emergency situation.
note: The normally off is not use. And may be use for some purpose.

Check for loose wiring at the light itself and also at the light switch. There can also be a loose wire anywhere in the circuit supplying power to that light switch. Start at the light itself and work backwards in the circuit until you find the loose wire.

How do you wire a motion security light from the box to the light?
You wire a security light like any other light. The sensor is generally part of the light and provides an "auxiliary" switch to detect movement and switch on the light, usually only after dark.The regular light switch for the security light should be left "on" at all times and labeled or enclosed to prevent being accidentally turned off. The sensor will not work, and the light will not go on, if the regular light switch it not on.Many modern units allow you to "lock" the motion sensor on by using the regular light switch to turn off the circuit and quickly turn it on again. This makes the light stay on until morning, when the photocell will turn it off and reset the lock, even without any motion detected.

What is maintained and nonmaintained emergency light?
maintained is where the light is constantly on all the time, For example,, when you go to cinema, There will be a maintained emergency light on the top of the exit door. This light will on constantly no matter the normal AC power outage or not. Non-maintained is where the light is normally off until power loss or emergency situation. For example, In the corridor , there always a non-permanent emergency luminary & a normal luminary. When the AC supply work well. We turn on the normal luminary to light the corridor by switch, The emergency luminary keep off. Once the AC supply outage, the normal luminary can't work. The non-permanent emergency luminary will turn on automatically.

You have a 1991 Chevy lumina it is hard to start when running the emergency light is on the emergency light flickers on and off when braking?
First of all, I don't think the 2 are related...hard to start and the brake light thing. As far as the emergency brake-I don't recall, but the light staying on might signal that a brake light is burned out. I'd check my brake lights first. Second, and I don't know this for a fact either because I never looked on my LUmina. But on other cars, here's what I'd do: after releasing the emergency brake, take your foot and pull out on the emergency brake pedal to make sure it's returned all the way out. If the light is still on, look under the dash at the emergency brake pedal and locate the "switch" that's activated by this pedal and make sure that the switch doesn't need adjusted. When the emergency brake pedal is fully returned, it should not be STILL hitting the switch. You can adjust this switch. Assuming I'm correct about the switch being there...after I verified that the switch is not needing adjustment, I'd fiddle with this switch (spin the plunger, check the wire connection...things like that) to see if I could get the light to go off...indicating that the switch is frozen. After this I might disconnect the wire to the switch to see if the light went out.
