I have a 2017 F-150 4x4 and have a quick flash situation because of LED rear bulbs. Where are the turn signal flashers located?

 

We dont have a flasher module. You will have to install load resistors or learn about Forscan and how to disable your bulb outage values to avoid hyper-flash. This changed in 2009.

 

Yep. Just what Summers22 said. Gone are the days of electro-mechanical relays and flashers etc. It is controlled by the Body Control Module, or BCM. Check out the FORScan thread and you can take care of it through simple programing, plus so much more.

 

Telling your age asking that question. Those old electro-mechanical flashers are gone, all controlled by the computer now. Even the sound of the signal light is artificially created by the computer. No more click clack of the mechanical flasher working.

 

Thank you! Yup, I am an old guy and fixed my Rubicon last year with this issue by installing resistors recommended when the LEDs came. Guess that I just assumed the new trucks were all the same as years ago but also read the literature from the LED manufacturer and they had a replacement flasher you could buy..? Anyway, when I ordered this Roush F-150 from a dealer in the mid-west, I assumed too much and thought everything was LED with this supercharged toy (didn't know that much about the Ford sub-models). Anyway, do appreciate the quick response to my query!

 

I always find it amusing when people install LEDs and then put in load resistors, but I guess it depends on your reasoning for the LEDs in the first place.

 

99% do it just so they have LED lights and think it is cool/neat.
It's not done to be more efficient.

 

Installing resistors will give you a hard wired solution. However this also opens you up to mechanical failure from bad connectors and etc. These resistors put off a lot of heat and bring you a step back to the "relay" days. The FORScan programming is the logical way to correct this.

 

You can't beat the crisp on and off of the LEDs no lag like typical incandescent bulbs.
