I have an 2001 Ford F250 V10 CCSB.
I installed 3157 LED Brake//Turn light. Now when I turn in my left turn signal it blinks fast which I can live with that but it would be nice if it blinked at the regular pase. Here my big problem. When I turn on my right turn signal there's a loud squeal in the cab of my truck. !!!

Any tips and help would be greatly appreiated.

 

That's odd, don't know what it really could be but DDM tuning sells LED blinker relays that correct the fast flash etc for $11. Did the issue only occur after installing the LED's?

 

Thanks for the response. I will check out there website. It all started after I installed them. Everything worked normal before I put them in. I also installed LED back up lights at the same time

 

you need a resistor

 

You need a resistor or an LED flasher.

With regular light bulbs, the resistance of the bulb determines the flash rate. (This is why you would see the turn signal flash twice as fast when a bulb was burned out). The LED bulbs do not have this resistance. A resistor will restore the resistance, or a flasher designed to work with LEDs should be installed.

I recommend the flasher.

 

Sorry to hijack but I have recon tail lights and I want to use LED front blinkers. If I add them will I get the hyper flash? Also of I would, would the flasher fix it even with the recons?

 

I just acquired a 2006 F350 SD and upgraded tail/brake/turn signal lights to LED. To my dismay, the turn signals were blinking fast. Thanks to this tread I ended up purchasing online an LED flasher and fixed the problem. FTE rocks!

 

Yes. Unless you also install a flasher or resister with the new LEDs.

 

I installed Phillips 3157 intense red LEDs in my 2002's (with 2016 body) tail lights and used resistors of the same brand; Philips 21W "Vision LED CAN-bus Warning Canceller, 2 Pack." This prevents the hyper flashing common to LED retrofits.





The resistor has to be hooked up to the ground/black wire (indicated on the harness plug) and the "major" wire as indicated on the harness plug, which is the colorful wire.



Quick tip. Add some silicon paste into the plastic wire taps to prevent corrosion, right where the tap makes contact with the OEM harness.

Then use some heat transfer Arctic Alumina thermal adhesive (2-part epoxy) to permanently glue the resistor in-place and assist it in transferring heat. Its cheap via eBay or Amazon.



The resistor fits up against the bed's wall behind the tail light and doesn't inhibit the light from fitting properly. Make sure you smear the entire base of the resistor with the thermal adhesive to maximize contact and heat transfer.






Use some tape to hold the resistor in place while the epoxy cures.
