I installed these bulbs in the front sidemarkers of my car... but apparently they can only run in one of two ways, dependant on how you put them in the sockets. Either they will work as blinkers and not work at all when the parking lights are on, or they will stay on as parking lights and not do anything else. Flip them around in the sockets and you get to pick one or the other. My question is, how can I get it to work like it's supposed to?

 

You could try putting 2 LEDs in there with the polarity opposite of each other.

 

That would almost fix the problem, except it still wouldn't blink when the parking lights are on. I really want it to work like OEM.
