Why won't your replacement light fixture work when your tester says the wire is live?

If this is a screw in bulb type fixture, the frist thing I would look at is the center tab inside the sockit where the center of the bulb makes contact. With the power off, take a small tool and gently pull the tap up a small amount, then give it a try.Other things to check is to do a continuity with your meter from the center contact to the black wire end and from the side contact to the white wire end coming out of the fixture. One last thing to check is the nentral wire from the mounting box. Do you get a good reading from the black wire to the white and from the black wire to the ground.

Where does the switched live go in a ceiling light?
To the black wire on the fixture.
What if your ceiling light does not work although there is power to the live wire?
Is this a fluorescent fixture? Most fluorescents will not start if the fixture is not grounded. Make sure the fixture has the branch circuit ground wire properly connected.
How can i find out if the live wires i found in my wall are for a light switch or an outlet?
Use a voltage tester held next to the wire. Turn the switch off. If the tester stops beeping then the wires are on that switch.

How do electrical testers work?
An electrical tester is tool used to check if a wire is producing an electrical current. Usually you will just hold it to the end of a wire, if an electrical current is being "induced" a light will glow on the tester, this is a live wire.

How do you use a voltage tester?
First, check if the voltage tester works by placing a tip inside one of the slots of a working receptacle or holding it close to a light bulb which is turned on. If continous flashes or chirps are heard, then it is an indication that the voltage is seen and the tester is working. Ensure that the power for the outlet is turned off from the main panel in order to test a desired outlet. Test the outlet's receptacle -you can insert the tip of the tester inside the receptacle slots. Just ensure all slots are checked as the top set may have been wired differently from the bottom set. Test the hot wires which are inside the outlet. Unscrew the receptacle and pull it out. Insert the tester deep inside the box to test for hot wires which may not be directly connected to the receptacle. If you find them switch them off from the main panel. Next, if you want to test a light switch, just make sure the power is turned off from the main panel. The cover plate must be removed and the tester must be placed closed to the screw terminals of the switch. Once the live wires have been tested, you can remove the screws and pull out the switch. Test the other wires which are in the box. To test a light fixture turn off the power from the main panel then turn the switch to on. Next, remove the bulb which is in the fixture and insert the tester to the bottom of the socket. Once you have confirmed that the power is off unscrew the fixture and test the wires.
Why tester glows in phase but not in neutral?
A mains tester works because the potential difference between the live and Earth makes a very small (imperceptible) current flow through the tester and our body to Earth. This current is just enough to light the lamp / Neon. When you stick it in the Neutral socket, the potential difference (just a volt or two, usually) is not enough to give sufficient current to light the neon.When the tester light glows, it mean electrons flow like,from live terminal > tester > body > floor & walls of building > inside the earth>goes back to the generator, via earth or neutral conductor (Please note that somewhere, Neutral and Earth are connected together so we have, in effect, a huge loop of circuit.) Above description is for AC supply only ( path complete thorough earth or nutral to generator neutral), however please note the fhilosophy is not applicable for DC supply where - V is in floting condition (not grounded or earthed) so due to un completation of that circuit tester light will not glow.

What is the reason for glowing of light in electric tester?
A small current is flowing through the light. In an insulated screwdriver with a neon tester, you put your thumb on the top and touch the other end on to the wire. It's best to make sure your other hand is behind your back and that you are not touching anything else. A live wire will light the neon. But if the neon does not light, that does not mean the wire is safe to touch. The power must be turned off back at the main switch before anything is touched.
What is the cost to replace a street light bulb?
The cost of the bulb is in the 30 dollar range. The cost to replace it depends on the hourly rate of the person changing the lamp and the additional cost of a bucket truck to reach the light fixture. This price will vary throughout the country in which you live.
When you turn off your truck the daytime running lights stay on when you turn the headlights on you have no high beams?
== == Sounds like a defective head light switch to me. Have a mech check it with a curcuit tester to see which contacts are not live.
Why does not tester light up when it is touched to neutral of 3 pin socket?
Because the neutral is simply the return path in a complete circuit. It doesn't carry any power - that's only found in the live wire.
