Don’t throw away good light bulbs

Try the bulb in another lamp – sometimes a bulb will work in a different socket.

Before discarding “bad” light bulbs, try these first:

1).. Use a wire brush or sandpaper to clean the threads of the light bulb.
(To remove corrosion.  Corrosion is not always visible.)

2).. If bottom of base of bulb is rough, lightly file or use sandpaper.
(The dull silver stuff is solder.  Solder is soft, so go easy.)

 

3).. Make sure power is off.  If the metal tab that is inside the light socket is bent downward, use a small screwdriver to carefully bend it upward about 1/8 inch.

4).. If threads of bulb have clumps of solder that could make it harder to screw in, lightly file or use sandpaper.

5).. This is normally not needed. If the bulb is contacting the top of the socket housing, removing about 1/8 of an inch of the housing will allow to bulb to go a little deeper and it might work.
You can do this only if the housing is plastic (as opposed to ceramic).

6).. Use a wire brush or sandpaper to clean the threads of the light socket.  (To remove corrosion.)
