Hi, I bought some Sylavnia Zevo LED bulbs to replace my current bulbs and when I turn on the turn-signals, they start hyperflashing. I changed all 6 bulbs (2 front, 4 rear).

Anyway to fix this?


2011 F-150
Used the Sylvania Zevo 3157R (4 bulbs, rear)
Sylvania Zevo 3157A (2 bulbs, front)

Thanks

 

Get used to it the dash indicators hyper flash to indicate a bulb out due to the reduced load of the led light. I believe if you check even tho the indicators are hyper the actual signals are still flashing at normal speed. you can install a ballast resistor at each signal but that kind of negates power saving of the led lights.

 

Does anyone know if I can get a LED flasher module to swap out the existing one? This way I dont have to put a load resistor on each bulb?

 

You can disable bulb out detection with ForScan. A lot better then splicing resistors into wiring.

 

Yes it's available. Google it. It's what i did.

 

Or just install resistors, which is what their sole purpose is to do.... stop that hyperflashing.

 

I know it's an EP27 flasher for leds, for older model trucks. Not positive on a 2011.
It is located up under the steering wheel, by the pedals.

 

I had a Ranger with LED bulbs and ended up changing the flasher to stop the hyper flashing don't remember the number of the replacement I may be able to get the number if you would like.

 

EP27 for leds.

 

I'm pretty sure your year can only be disabled via a resistor. There's no blinker module for you and I think you can only update the PCM for 2013+ years.
