Does anybody Know if the 3157 LED switchbacks used as Tail/Brake in a 2017 F250 are standard socket or CK. Or do I have the wrong bulb size?

I bought Alla T20 Switchbacks for the front signals only to learn my truck requires the 4257 bulb. I'm returning those to get a 3157 switchback I went with iBrightstar 3157 bulbs for the rear stop/turn/tail lights. I do have Hyperflash but I'll resolve that.
I used JDM ASTAR 1200 lumen reverse lights and am super happy with them.
I haven't done the front side marker bulb or license plate bulbs yet. They are both T10 but orange LED for the front and White for the rear.
I already have LEd's in my cargo light (2019 STX)
I'm running the SuperNova V4 from Headlight Revolution ... very happy, much improved. Have driven several times at night and not getting flashed by on-coming cars.
Love the look of those 5 lights in the grill, what brand? How much? Any issues?

Are you sure a switchback is being use for rear tail/brake lights? Seems odd to me to have a bulb that flashes from white to amber (which is what a switchback does) inside of a red lens.
When in doubt, I've always gone to Superbright LED's website. Even if you don't buy from them they have a good reference for every bulb on the truck for you to find the correct bulb number.
I have the beamtechs on the way for the headlights but what brand do you guys recommend for the reverse, license plate and the upper break light/bed light on the top of the cab ? I'm not replacing the break or turn signals right now, so I don't have to deal with any issues with hyper flashing.
I also have beam tech bulbs and their fog. I did led brake lights and switchback fronts. Here are the ones I bought. Very happy bright no issues

My bad, I meant duel filament Red 3157's Stop/Tail. Superbright LED website say's My truck use's a CK type bulb, I Was looking for conformation, Yea or Nay.
Someone who already tested with a DVM.
Thanks, DaveyMac
Reviving this thread for a quick question. I have a set of these LEDs sitting in the garage. Never got around to putting them in my previous truck. Will they work on the 2017 Platinum I now have in place of the license plate bulbs? Or are they already LED from the factory?
