My headlights and dashlights are at times flashing. It is not real noticeable but has a definate pattern, like a relay is causing it. it dosen't do it all the time.At 1st I thought it was a bad ground but it will do it with the engine off orstopped at a light. DoI have a relay that would cause this and where? Anyone have any ideas?

 

Could be your alternator starting to go, check the grounds at the battery and check the connections to the alternator and make sure its all clean and free of corosion.
