LED parking/turn signal bulbs up front

[Colossus]

Have any of you installed LED turn signal/parking bulbs (3157) up front in your factory stock headlight housings?  if so, did you encounter a hyperflash situation?  Trying to decide if I want to replace the stock turn signal bulbs with LEDs as I get ready to replace my headlight housings (staying with halogen headlights) 

 

We have LED lights in the mirror turn signal things so not sure if there is already a built in load equalizer in the lighting circuits, or if I'll need to add them for new LED turn signal bulbs up front to prevent hyperflashing. 

 

Thanks

I put all LEDS on my 2009 3500HD.  Had to use resistors for the turn signals.  We must have messed up wiring the right one since it hyper flashes if I have the running lights/driving lights off, but not when they're on.  I need to find shorter T10 LEDs all the ones I've used or seen are too long to replace in the fender/clearance markers in the rear.

I just put these in my 2001 HD, front and rear. Remember to color code as needed. I needed 4 orange, 4 clear and 2 red, clear are for Reverse and DRL.

I did find these all cheaper on Ebay.

I used these in the outside front blinkers.

Odd, using the flashers in the driveway, everything worked good but using blinkers I have hyper flash issues. I ordered a new LED flasher relay, going to try that next vs adding resisters.

4 ways won't hyper flash.  You have an '01 with the flasher relay you'll be fine.  Colossus and I can't use relays b/c we don't have them.  They're controlled by the computer or whatever it's called.  We need to use resistors.

Just did finished this up this week, replaced parking lights and flashers, got hyper flash and then installed the Sylvania resistors from oriellys. Worked like a charm, needed 4 resistors one for each light.
