interior lights flashing
 

I'v had this problem off and on for a few years. Now something is draining my battery to the point it won't start. I checked all the fuses to find a draw on the batteryand it seems to be pointing to #1 which is the interior dome lamps. Is this a common issue with them. Is there a direction to which I can fix it. I can't afford another trip to the shop. i've fixed enough things this year already.
