10/7    I've got this weird light socket in my house. The lightbulb in it
        is good because I tried it elsewhere and didn't have problems.
        The light goes out after about 4 minutes and 15-30 seconds. It
        turns back on pretty consistently in about 1 minute, 40 seconds.
        It makes a clicking noise when it goes on or off this way.
        Any ideas?
        \_ I've had something similar happen with a dimmer switch.  Is there
           one?
           \_ nope.
        \_ If this is a ceiling socket (ie, not a lamp) it might be that the heat
           from the bulb is causing something to overheat.  Get an electrician
           to take a look at the wires and make sure they're not overly damaged,
           and then have him replace the socket.
           \_ or if you are lucky, it is a newer socket with a built-in
              thermal cut-out to prevent damage.  try a lower wattage bulb.
              \_ it's 50 watts. i'm not so sure about going much lower than that.
                 compact fluorescent might help with a heat problem though.

                 \_ I caution you, open flames can lead to the immolation
                    of entire cities.
                    \_ Wasn't the Chicago cow story a myth?
           \_ Wave a fan at it while its on and see if it stays on longer...
              If it cuts off just as fast, you know not to worry about heat.
