I have a 2013 f150 and recently install some aftermarket headlights. They are from the company Autosaver 88 and have a drl led bar that has sequential switchback turn signals. They were super easy to install but after about a month the turn signals(Amber) stopped working and now I have a hyper flash. The side mirrors and back lights work but hyper flash. The DRL white led bar works but doesn’t when I try to use the turn (amber) signal. I’ve looked on many forums and looked at many videos but can’t find a specific answer. Will disabling the front turn signal outage with FORscan fix my issue or is it something I have to change a code on. Hoping someone can help. These are the link to the type of lights thank in advance! https://a.co/d/6XXCFRh

 

If the turn signal completely stopped working, sounds like your aftermarket lights are the problem. Warranty?

Yes, I believe changing the proper code with forscan would stop the hyperflash. But, that won't fix the non-functioning light.

 

I have put on the original headlights back on to see if the turn signals would work and they don’t. I have also changed the bulbs thinking it might be that but they were never burnt. So I figured it might be something I could fix with forscan but not sure where exactly to start.

 

I would assume the light bar shutting off during a turn signal is normal behavior. Can't guess what might cause the turn signals not to work with anything other than damaged wires.

 

I am experiencing the exact same issues and I’m wondering if you ever figure out what was wrong so I am able to fix it on my truck.

 

I'm not sure what you're working on, but if it's an 09-14 I would use Forscan to scan the BCM for any fault codes.
The BCM can shut down a circuit if it senses a high current draw like when a bulb burns out.
I don't know if an led will draaw high current as it dies, but worth a look.
