I have a 2022 F350 XLT with blind spot & cross traffic warning. I’m looking to replace the turn signals front & rear. I will be going with the GTR Lighting 2.0’s. Switch backs in the front and amber rears. What’s the bulb size for them?

Thanks

 

I don't have the answer but your owners manual should.

 

Didn’t think about looking there, thanks.

 

I would strongly suggest you pull the existing bulbs and physically check them. On my truck the manual was different from what was actually in the housing.

 

I have GTR switchbacks in my 2020. https://www.gtrlighting.com/gtr-ligh...443?quantity=1 OR https://www.gtrlighting.com/gtr-ligh...443?quantity=1

GTR has pulldown menus to use to determine which bulb for your model.
Here's a list of what I used in other spots on the truck for LED replacement:



But contact whichever vendor you choose to verify fitment.

 

OK, I pulled the switchbacks out of my 2020 yesterday before I took it in to trade. GTR Armor series, number 4257. Great bulbs that snap in very securely. I had other brands in the past that I had to wrap with electrical tape to secure. Not so with GTR.

 

When installing the GTR bulbs do you also have to install a inline resistor so that your turn signals don't blink really fast?

 

Not if you use the GTR Carbide 2.0. You also can use ForScan to stop the fast blink

Thanks for the tip on looking in the owners manual. Found out the bulb type and called Headlight Revaluation to cross reference the bulb and came up with 7443 single filament for the rear and dual for the front. As said, I’ll be running switch backs in the front. Also, CK Type bulbs need to be used in the turn signals only and non-CK in others. I’ll post pics and a vid of the lights!

Thanks
