If you have 120 v at the wires connecting to the light fixture the light should come on. Its possible the voltage is not getting to the inside of the socket. Carefully measure the voltage between the metal blip at the bottom of the socket and the metal along the sides. Be careful here. Its tight quarters and easy for the voltmeter leads to touch the wrong things. Before doing that I would try a third light bulb. I've gotten them bad right out of the package. If you have voltage inside the socket, then for some reason the light bulb is not screwing far enough down so the bottom touches that metal blip on the bottom of the socket. If you don't have voltage inside the socket then that's your problem and you'll need a new socket.
A fixture is what the light bulb goes into.
The light is wired the same as any voltage fixture. Bring the source voltage to the fixture and connect it to the two fixture wires. If you want to control the off-on of the fixture take the source voltage to a switch first and then out of the switch to the light fixture.
Disconnect the fixture wires and remove the central mounting nut to release the dome from the light fixture in a ceiling fan.
It just holds the bulb, does not have a switch in the fixture.
What needs to be checked is the voltage of the low voltage line. If it is 120 v, that is suitable for a 120 v LED fitting. Second, is the line capable of carrying the current needed by the fixture. The answer to that is, probably, but it still needs checking.
Look on the label of the fixture ,it will tell you the maximum wattage the fixture will safely handle.
multi function switch
Yes
Switching a light fixture requires the following steps. First, remove the old fixture. Second, you must disconnect the wiring. Third, a junction box must be installed. Finally, a new fixture must be installed. Detailed instructions can be found here: http://www.diynetwork.com/how-to/replace-a-bathroom-light-fixture/index.html
take it to a pro wiring is very tricky if you do not know what your doing
It sounds like you are describing either a slimline or dc recessed base type of fluorescent fixture. There is a wiring diagram on the ballast of both of these types of fixtures. Do your wiring the same as what is shown and you will have no problem.
There will always be a way to dismount the fixture. Look for some screws, they are usually hidden from sight.
Check ground on that fixture short in the wiring it sounds like
Wiring Up a Light FixtureWhen remodeling a dining room, the light fixture can become a hazard if it is hung low enough. Banging one's head on a chandelier or heavy light cover hurts. If a light bulb breaks, it can become dangerous with broken glass in the eyes and under the feet. Wiring up a low-hanging light fixture takes a attention to a few details.Remove the table and chairs so access to the light fixture chain is unhampered. Set up a stepladder close enough to the fixture that it is easily worked on without the person leaning away from it. If the light covers are in the way, remove them to a safe area. Determine how much to raise the light fixture so people can walk under it safely.For raising the fixture temporarily, use a piece of baling wire or heavy construction wire. Place the wire through two of the chain links and lightly twist with a pair of pliers. When the work is over, remove the wire and lower the light fixture.If permanently raising the fixture is desired, purchase a connector link from the DIY store that matches the light fixture chain. As with the wire, attach the connector to two of the links and leave in place.This can be done with any light fixture in the home, on the patio, entryway or porch. For lights hung with cable, use a hose clamp spray-painted to match the cable. Do not over-tighten.
If an immobilizer light on a 2005 Peugeot Boxer will not go out it indicates a problem with the wiring. The immobilizer can be by-passed until the wiring can be checked.
A fixture is what the light bulb goes into.
If these are all the wires you have then this would be a great assumption. It assumes also that everything before the fixture is wired correctly and with commonly used color schemes.
