led lights now dash ind are on....?

[Dzznuts]

I bought the plug in style led (lens') they are the ones that plug directly into the light sockets. I put tail and park lights in now only when the lights are on the dash indicates both front lights are out. I've bought 2 different flashers and neither fix it. blinkers work fine, lights work great. Just when I turn the lights on the dash ind are on solid, don't flash when blinkers are on either. Any ideas?
I was thinking maybe a diode?
I have bought flasher from LMC and other one with ground wire.....
Not sure if it matters but I have Dakota Digital VHX gauges
