led in parking lights

I got a superduty and trying to convert all my parking lights to led. The problem I'm running in to is the flashers and turn signals. Anyone have any ideas?

What's the problem? CANBUS? Otherwise ensure you get a LED compatible flasher/hazard can, else wire the LEDs in parallel with the existing bulbs. (IMO ballast resistors is a stupid way to go.)

Resistors are good, in one way; to find the one that will JUST be enough to stop the Hyperflash or error. The whole idea behind LEDs is for lower power consumption. wiring with the bulb hidden, still uses the the same current, and defeats the primary purpose of using LEDS. I put LEDS in both my cars, when it is REAL COLD, my Jetta's parking lights come on, or just the plate lights. There is something wrong with the light switch in the car, but thank god I had LEDs, because it started right up.... I was able to duplicate the condition by turning a little harder to the OFF setting, and the parking/dash lights would come on.   I will have VW fix it, it's all in warranty anyway... IF no errors, but you do not like the Hyperflash, they make LED flashers, as stated above. They return the flash rate to normal. Also, your title says PARKING lights, which is fine, then you go on to indicate turn signals and flashers...   I can tell you, LEDS do not work well with Thermal Flashers, and the 2006 Dakota doesn't work at all with LEDs...

Swap out your flasher relay with an EP27 electronic flasher and you should be fine.
