Factory rear turn signal light bulb part number #?

[poghr]

Hello, I had the Lasfit led rear turn signals for about nine months before one went out. I want to go back to the factory bulbs, but I am having a hell of a time finding them. When I put the part # from the manual all I am getting is led bulbs. Is there something I’m missing?

Try WT21 -7w sylvania or phillips. Any auto parts store should have them. Part is not unique to the maverick more of a common bulb number used by many models.

Please find me a store selling them, I can't find one

You can just go to o'reilly or autozone they can definitely give you the right bulb for it.They usually have it on records or physically check the rear lights of the truck.

Don't know if this matches the manual, but I can read you the numbers off some stock factory bulbs. I took mine out and put in LEDs.

Amber double filament is a Sylvania 4257NA
Here is the O'Reilly listing for them: https://www.oreillyauto.com/detail/...530/automotive-truck-2023-ford-maverick?pos=0

Clear double filament is a WT21 7 Wattts
I do not see an exact match online, other than the LED options you probably saw.

Clear single filament is a WT21W
This seems to be it, in a "Commercial Pack", which is why there is a "CP" on the model name (WT21WCP): https://www.partsgeek.com/zlw6hs7-f...2021&fp=pp&gbm=a&gad_source=1&cid=18313611776

I did a deep dive into replacement stock bulbs. After finding out how hard to find they are, I decided not to attempt any LED buld replacements in case things backfire. Someone in here mentioned a type that would fit after doing some trimming of the edges...........go figure!

The problem for me wasn't finding the bulbs.............it was finding someone who had them in stock.

Well, I just posted 2 of the 3 in stock. So you are 66.6% of the way there.

Agreed. One has to order them online as usual. I think most wanted to walk in your local auto parts store and pick them off the shelf.

I ordered replacement ones from lasco auto parts. Their part number is jl3z13466f. And they are showing in stock for now. I have gotten my order and they are the correct bulb.

Thanks everyone. I didn’t think it was going to be such a pain in the butt to find these.

I’m in the same boat with trying to find these damn bulbs. I ZEP’d my tail lights and switched to the Lasfit LED’s but half the time they don’t work so I’m switching back to stock. Luckily I kept the stock bulbs but unfortunately one of my stock bulbs has already burnt out and none of the local parts stores (Autozone, Napa, OReily’s) can get them. I tried 4257 bulbs and after trimming the base they fit in the socket but the bulb itself is too big to fit the taillight assembly.
I’ll guess I’ll have to order online and wait for them to arrive.

I called a local Ford dealer and they had the taillight bulbs in stock.
jl3z13466f. It fits and works.
