🚨FULL DISCLOSURE🚨 I have heard people having issues with these brake lights and cannot confirm whether they have fixed the issue or not. In the mean time I put a link for VERY similar lights that seem to be working perfect for people. As always I try to be VERY honest with my viewers. If I use something and it doesn’t meet my expectations I WILL be letting you guys know about it. Take care.

These bulbs did the fast blink on my 2022 f150. I went into Forscan and changed it so it didn't fast blink.

[@DanielHernandez-qw6gi]

Awesome lights. I have been waiting to see something come out for the 2021 F150 tailights. Thanks for sharing!!!

[@AutoHeadz]

Thanks! They look awesome. Thank you for checking out my video! 🤙🏻

[@samuelzukauskas8233]

Awesome lights. Looks sick

[@The_Good_Life_starts_today]

Thanks for the video. FYI whenever I work off of the tailgate (or most any hard surface), I'll lay a towel down. This helps keep it stable and prevent scratches to the outside lens.

[@Ahmad-yw5hl]

I need this!! Thank you so much.

[@AutoHeadz]

Hahaha they are a nice touch. Thanks for Watching!

[@blickyboyz0120]

Thanks!

[@AutoHeadz]

THANK YOU!!!

[@jlane7731]

I’m too late for the giveaway. Dang. Lol. Thanks anyway man. Thanks!

[@genedavis7021]

How doin fellow Vet. I purchased the lights I saw on your video. I have a 2023 F150 XLT and after I installed the lights they flash fine the only thing is I have hyper flash on the instrument cluster are you experiencing the same?

[@EMORRIS2312]

Thanks for the video. I purchased these and did not have the best of luck replacing the halogen bulbs in my 2021 XLT. I did exactly what you outlined here and the bulb at the top worked but did not get brighter when you applied the brake or turn signal. One of the 4 bulbs did not work at all out of the box as well so I gave up.

[@AutoHeadz]

That’s unacceptable. Please reach out to Auxito for a replacement. If they don’t hook you up I will. The bulb on top won’t necessarily get brighter it is just a brighter bulb in general because it has more LED’s. Did you make sure to cut the tabs off as seen in video? Send me an email and I will make it right for you. I stand by everything I show my viewers on my channel. [e-mail]

[@travisc3571]

Probably need to reverse the bulb.

[@connerellsworth8736]

Just to confirm, both bulb sizes are the same and it’s 3157?

[@brianbudd8487]

Any issues with the truck thinking the bulbs are bad?

[@scsurface1]

I just put two of those Alla LEDs in the top. No fast blinking inside or out. Will they work in the bottom as well?

[@AutoHeadz]

That’s good to hear. Thank you for letting me know. They should yes! Same exact setup.

[@scsurface1]

@@AutoHeadz now 1 already stopped working

[@RedSizzler]

Does this give you any warnings on the dash at all that a brake light is out? I know that happens with most led bulbs and requires a resistor

[@AutoHeadz]

It doesn’t give a warning it will just increase your blinker speed. It never bothered me but if it does I ford can plug it in and just shut that off. I’ll probably get it done myself next oil change.

[@travisc3571]

If you go into Forscan you can change it and it will not fast blink anymore. It’s well worth it.

[@The_Good_Life_starts_today]

That probably should have been mentioned in the video. When folks watch the UTube on TV, comments are not visible (that I know of).

[@darkom.120]

Do they cause hyper flash?

[@buffalobmf]

They arnt going to hyper flash when you use your blinker? Didnt see a resistor put on

[@AutoHeadz]

The lights themselves don’t hyper flash but you will get the extra click in the cabin.

[@angelomiranda331]

Do you have any issues with the hyper blinking, if so did you add resisters?

[@AutoHeadz]

Yes it does hyper blink. I never installed resistors. I plan on using FORSCAN to shut it off.

[@angelomiranda331]

How do you do that?

[@nighthawkone6770]

I have the same taillights as you. Do you know where the reverse light bulbs are?

[@AutoHeadz]

Hey man, so if you have the same taillights as me there actually aren’t any reverse balls, per se. It comes with a built-in LED light that integrated into the housing. There is really no way to change it unfortunately without getting way too complicated.

[@nighthawkone6770]

@@AutoHeadz Thanks I figured that.

[@pierreguertin7674]

Hi, i see you are not using any resistors…are they built in?

[@AutoHeadz]

Yes. They have a canbus built in.

[@HRO148]

No load resistors needed? Nice!

[@AutoHeadz]

You will get the double click noise inside when using the turn signal. The dealer can shut that off with a simple scan if needed.

[@shwanalkhalifa4212]

Which website I can order it?

[@AutoHeadz]

Links to purchase are in the video description. Use the code: “AUTOHEADZ” for the discount.

[@georgewilliams6328]

Will these break lights fit a 2014 f150?

[@AutoHeadz]

Yes they will!

[@georgewilliams6328]

Thanks, great video BTW👍

[@AutoHeadz]

Thank you Sir!

[@AndrewNobleOfficial]

Did it make that pop noise when you pushed it in or did you add that in post editing? 🤣

[@AutoHeadz]

Lol, I wish it made that noise

[@AndrewNobleOfficial]

@@AutoHeadz so awesome 🤣

[@DanielHernandez-qw6gi]

One of my bulbs doesn't blink. All others blink. They all turn on. Not sure if this happened to anyone?

[@AutoHeadz]

It’s got to be a defective bulb. Please reach out to Auxito for a replacement. If they don’t take care of you I will.

[@scsurface1]

Ok , done with DIY LEDs. 3 sets....none work.

[@jlane7731]

Brake lights….Which ones. Bright red? Ps. Don’t kick the old dog to the curb(2016 f150). Lol. Peace

[@AutoHeadz]

Yes. The link for them are in the description. Also I got 10 codes left for 20% off AUXITO and LASFIT for Valentine’s Day if you need something. The code is “LOVE4U” at checkout. Happy Valentine’s!
