Here's a neat idea I read about yesterday which might help solve your problem. If you suspect a bad ground as noted above. Put one lead (+) from a voltmeter at the point where a lamp is grounded, like it's socket base. Put other voltmeter lead (-)to battery post ground, you may need a piece of wire with clips to do this. Set voltmeter to read battery voltage and excite lamp (put brakes on, flip turn signal on, etc.). If the voltmeter reads anything but a wiggle you've got a bad ground somewhere. Good luck.
