LED signal lights on a 74 Dart

Hi all,

On my 74 Dart I thought it would be nice to brighten up the lights. Checking the forums here I found lots of useful information. Thanks to all that contribute. Here's the situation...

LED lights all around, marker lights, brakes, front signals etc. All the more expensive Phillips LED bulbs.

All the lights work when the headlight switch is pulled to park. Looks great. Hazards work just fine with the original flasher. Signals don't work, just light up solid, no flash with the original flasher. No problem, expected this based on the forums, replaced the turn signal flasher with the LED flasher with the pig tail to ground, now no signal lights at all. Tried to use the old incandescent bulbs up front, same thing no light with the LED flasher, solid light with original flasher. Not sure what to try now, suggestions? It seems like it should work especially since they all flash on hazard.
