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.
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.

The screw socket into which an ordinary light bulb is inserted.
My first suspicion is you have a loose or disconnected neutral. TURN THE BREAKER OFF WHEN CHECKING THE CONNECTION. To include all points, even the obvious, make sure you have changed the lamps to known working lamps from another fixture. How do you know it has 120 volts at the socket? If you tested it with a voltage tester or a multimeter, which wires were you connected to? In order to troubleshoot you need to make three measurements, at the BOXif wall or ceiling mounted or RECEPTACLE if plugged in with a cord, not the fixture socket the lamp screws into. Hot to ground (volts AC) Should be 120 volts nominal. This can vary from about 110-130v. Hot to neutral (volts AC) Should be 120 volts nominal. Neutral to Ground (volts AC) Should be 0 volts. These wires are electrically joined at your main panel. If you have 120v hot to neutral, your circuit is working properly. Any problem will lie in the fixture or the connections to the fixture. If you do not have 120v to neutral but you do have 120v hot to ground, your neutral is not connected. TURN THE BREAKER OFF and check the connection. If you do not have 120v to neutral or120v to ground, your hot is not connected. TURN THE BREAKER OFF and check the connection. If you have anything other than 0 volts neutral to ground, your fixture connection may be okay, but your neutral is not connected properly going back to the main panel. This is a dangerous situation, and it can result in fire over time. In this case have an electrician inspect the situation immediately!
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.
Switching light on/off through loosening from socket is not advisable. Light bulb can reach at temperature between 200-260 degrees Celsius and it can be hazardous in physical contact.
To safely test a light socket, first turn off the power at the circuit breaker. Use a voltage tester to check if there is any electricity running through the socket. If the tester indicates no power, you can proceed to test the socket by inserting a working light bulb. If the bulb lights up, the socket is functioning properly. If not, there may be an issue with the socket or wiring that requires further inspection by a professional electrician.

Since the problem either lies in the light socket or in the power cable diagnosing the problem requires access to the connections. The most easiest method is using a continuity tester which has two electrodes attached to a digital meter.
To test a light socket with a multimeter, set the multimeter to the voltage setting. Insert one probe into the hot wire slot and the other probe into the neutral wire slot. If the multimeter reads a voltage, the socket is working. If there is no voltage, the socket may be faulty and further inspection is needed.
yes just make sure your not using too much amps...
If the house wiring does not have a white wire, you can cap off the white wire from the track light with a wire nut and electrical tape if necessary. The white wire is typically used as the neutral wire, but if it's not present in your house wiring, capping it off safely will ensure the track light functions correctly with the available black and green wires.
To extend the reach of your outdoor light socket using an outdoor light socket extender, simply plug the extender into the existing socket and then plug your light fixture into the extender. This will allow you to position your light fixture further away from the original socket while still receiving power.
On an Edison screw (ES or SES) it is in the bottom of the socket not the sides where the lamp screws in that is the neutral connection. On a bayonet catch (BC or SBC) it is either of the two pins, the other being neutral.

To change a light socket, first turn off the power to the light fixture. Remove the light bulb and unscrew the socket from the fixture. Disconnect the wires from the old socket and connect them to the new socket following the manufacturer's instructions. Screw the new socket into place and replace the light bulb. Turn the power back on and test the light to ensure it is working properly.

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.
