not liking to admit to doing something wrong. when replacing the right lamp I didn't make sure it was tight and in-place in the socket. so when I turn my lights on it just lit up in just a steady light, no flashing. Sure enough I was a 1/4 turn off or so. No problem I turned it into place and were off, problem fixed. Except every once in awhile when I turn my lights on, it will just flashes one time or stays on for a couple of seconds or maybe flash a few times. never lasting more than a few seconds. Then after they have been on for a short bit, no problem until the first time you turn on the lights the following day. not that big of a deal, except I kind of like everything to be just so so.[:-]anyway, be careful.

 

Put another bulb in with dielectric grease on the contacts.
Chanches are, the bulb that's in there now has a loose filament.
