Yes a T12 lamp socket will take a T8 tube. The T8 tube will not operate. The T8 ballast is an electronic ballast where as the T12 ballast is a magnetic type. If you are changing over fluorescent fixtures to the smaller T8 lamps then the ballast has to be changed and the end sockets have to be rewired. The schematic on how to do the rewire is on the electronic ballast's label.

No, you cannot replace a T8 bulb with a T12 bulb in the same fixture. They have different diameters and require different ballasts to operate. It is best to use the correct type of bulb for your fixture to ensure proper functionality and safety.

You shouldn't because the ballast in the light most likely is older and won't b compatible with T5's. The bulb could flicker , basically not function correctly

If a fluorescent light blinks is the light bulb bad or the ballast?

If a fluorescent light blinks, it is more likely that the issue is with the ballast rather than the light bulb. The ballast helps regulate the flow of electricity to the light bulb, so a flickering light is often a sign that the ballast is failing.


I am installing a kitchen light fixture in the ceiling. While pulling down the old fixture the green ground wire broke. The new Fixture has a green ground wire. Where do I ground it to now?

You can ground the green ground wire from the new fixture to the metal junction box using a grounding screw or grounding clip. Make sure the junction box is grounded properly to ensure safety.


Can you use New 100 watt bulbs that use 72 watts of power in a 75 watt fixture?

NEVER! NEVER! NEVER! The current draw from a 100W light greatly exceeds the design limits built into the 60W fixture. The end result would be a fire. You can use florescent light bulbs to get more light with less amperage. You get 100 watts equivalent lighting for 23 watts and will not create a fire hazard.

It depends on which bulb is burnt out. If it is the front bulb in the bumper you can reach up behind the bumper and unplug the socket and replace the bulb. You may need to loosen the valance to reach up to the bulb. If it is the bulb in the front side marker just take out the screws and remove the fixture, the socket can then be removed to change that bulb. If it is a rear bulb in a sedan or coupe: 1. Inside the trunk near the quarter panel on the side the bulb is burned out on there are three nuts. Remove the middle nut, it should be in the middle of the tail light fixture. 2 Pull the stud out of the body then pull gently away from the center to remove a tab from the backup light fixture. The fixture should now be loose. 3. Remove the appropriate socket and replace the bulb. Reverse the procedure to reinstall the tail light fixture.

How do you remove the headlight assembly to replace a bulb?

Modern headlight assemblies are just lenses and are really more part of the body than they were in older cars, to replace most all headlights on modern vehicles look under the hood behing the outer headlight lens and there is a bulb receptacle that inserts into the fixture, now it varies on how to remove it from one manufacturer to the next but that receptacle will either have a locking ring or will simply turn out of the back of the lens and you can pull out and replace the bulb from there. Be careful not to touch the bulb with your fingers to help it last longer, fingerprints or oil will cause the halogen bulbs to burn out quickly.
