No go for me with 3157's. Even shaving the nubs off, the base was the tiniest fraction too wide for the socket. Didn't fit securely and stretched that socked just enough that it would not fit into the headlight housing. In fact one bulb fell out and into the headlight housing as soon as I began to push the socket into the housing. That's another story but I was finally able to fish it out.
I don't expect a refund or any other recompense from Superbright, as I altered the bulbs. I am, however disappointed that they told me ahead of time that these bulbs would snap right in and that they'd never had a customer complaint about these bulbs with this particular application. And they most assuredly did not ever mention the nubs being a problem.
I reinstalled the Alla LED switchbacks I had. Not as secure as they should be but a wrap or two of electrical tape and they're good. Why is it so hard to find a bulb that will snap into place without modifying the base? Ford got the incandescents someplace, someone else should be able to come up with a suitable LED replacement.
One of the great things about standards is that there are so many to chose from. [I wish that I could take credit for that line.]
Photos aren't fantastic, but hopefully they make the point. The base on the stock 4257NA is the tiniest bit narrower than the 3157 LED sent by Superbright.
Also, the nubs (apparently also known as "locking tabs") for the stock bulbs are on the on the wider side of the base. The replacements have the nub on the narrow side.
Could I have ground them to make them fit? Probably. In fact I did grind the nubs off of one replacement but did not attempt to narrow the base on it. But I'm guessing that I'd be no further ahead than I am with the current Alla bulbs that I ground the bases on as far as fitting securely. After spending an hour fishing 2 bulbs out of the headlight housing, I guess I'll just live with the current setup. It looks good and works as it should. The only reason I messed with it was to try and get a bulb that would snap in and fit securely as the factory bulbs. Surely I can't be the only person with this complaint.

I think the verbage in FORScan while into the BCM is changing it from "Outage" to "No Outage" for that particular key position.
I may be onto a good solution finally. Headlight Revolution sells a kit for $88 with resistors. Further research shows that the bulbs sold by HR are made by GTR and are 4257 compatible. The bulbs alone can be purchased from GTR for $59. I'm just waiting for confirmation from them on fitment. I've made FORScan adjustments so have no need for resistors.
Just ordered a set from GTR. They also recommend and sell resistors but I told them I'd skip the resistors because I'd already sucessfully done the LED switch a couple of times with FORScan.
Will report back on the fit when the lights arrive.

I can confirm that these lights from GTR, DON'T fit in 2017 F 250 front sockets.
I'm in process of returning to GTR now. Waiting to here from them ???
I can confirm that those GTR 4257's are indeed in and functioning in my 2019. Could Ford have made some change to the sockets between those model years? Nothing surprises me anymore.
And looking back on my previous post, I guess I never did report back on the fit. Sorry! But again, they've been installed and working in my truck since September 2019.
The bulbs I installed are pictured. No idea if the number is an actual part number, lot number or what or if it's subject to be changed. A search of that number turned up nothing for me.
Thats what Im thinking, They Must of change sockets, Here is the Factory Part# for stock Incandescent bulb, OEM Ford Blub And it's not a 7444na or 3157na. Base of Bulb Has something different than over the counter Bulbs you buy at parts stores.
Ford Part# DR3Z-13466-A

I went down the road you're on with my 2017. Many of the Amazon bulbs as well as places like Superbright LED were trying to say that their 3157 or 7444 bulbs were the solution. As you know, they certainly were not. The nub or "locking tab" wasn't in exactly the right spot and the base on these replacements were just a shade wider than the stock bulb base.
Myself and a few others took a Dremel type tool to the base and made them work, but to me it was not ideal and they could have been more secure.
I was pretty happy when those 4257 GTR bulbs snapped right in on my 2019. Seems strange that Ford would change the socket for something as pedestrian as a front turn signal, but these things happen all the time. Maybe they found a lower cost vendor for them.
If you find an answer be sure and post it so that then next poor SOB who wants switchbacks in his truck has an easier time of it.
Well I sent my GTR Lighting Armor Series 4257 LED Bulbs on 1/6/2020. I was in commutation with Elliot and was told he would help thru the return process.
Emailed the USPS tracker # and they were Delivered and sign for by some one at the provided address In Atlanta, GA on 1/9/2020.
A couple of e-mails I sent after Delivery All I get is Crickets from GTR.
As it stands as of Now "Future Buyers Beware". Someone should at the very least Let me know their busy and will get back to me as soon as the can.
Rant Off

Still happy with these? Any night pics of them, do they match the beamtechs?

I'm still satisfied with the result. But in all honesty I drive my little beater around most of the time. I bought the truck new on 9/4/19 and still only have about 1600 miles on it. Near the end of March it'll be going on a 2800 mile round trip for vacation. That should tell me more.
Do you means as far as color? If so, I haven't looked at them from the front of the truck that closely at night. But to me, a white light is a white light. None of the lights on the front of the truck has that bluish tint.
Sorry I don't have more for you at this time.

That sucks. I really hate the fact that this is happening when I recommended the lights. But something for me to keep in mind should any LED needs happen in the future.

Yes, as in color. I know some makers advertise as white, but sometimes they look too blue. Thanks for the update.
