Easiest way to fix hyperflash on LED turning lights? 2014 GC

I replaced my turning lights with LED bulbs from AutoZone. The bulb packaging itself says that the bulbs will not hyper flash... but they do.

I did some research and purchased a turn signal flasher relay on amazon that is supposed to fix this issue.

Well i followed the instructions and there is no turn signal flasher relay in my fuse box that I can replace.

Should I just go back to regular incandescent bulbs? Didn't think it'd be this hard to switch to LEDs.

Try the XenonDepot guys. They are forum suppliers and by all accounts are top notch. Send them an email and buy what they recommend. Some guys get into trouble mixing parts from different suppliers. XENONDEPOT - HID & LED Lighting Products

You can also search the vendor list at the top of the page and send them a private message. Not sure, but they may offer discounts to Jeep Garage members. Won't hurt to ask.

Also just an FYI, atleast on Overland and Summit, the actual bul outside does NOT hyperflash, just the inside indicator hyperflash es and ofcourse you get the bulb out warning everytime you start the car. So again, your outside bulb is flashing at normal rate which h is kind of cool.

The electronics is simply looking at the load. It is expecting a 21W bulb at the rear (the front/side are low power LEDS). An 8 ohm resistor will create a load of around 18W. The new LED bulb will add a bit more and make the car think it has the correct load (no hyperflash). Many LED bulb sellers supply 6ohm resistors. This creates more load than required and just creates extra heat. The resistors need to be rated to 50W to handle the heat they produce.

true, but these are not just used for turn signal application. Something to think about though if your hazards are on for prolonged periods of time...

Just making sure people understand how hot these things can get.

My 08' had the gold resistors and they got HOT...this was before XD made these lovely resistors! Will be changing out my brake lights (only OEM bulbs left) at some point, so these will come in handy. No Walmart/eBay "specials" for me...Thanks Steve :thumbsup:

The short and long of it, the power consumption needs to be equivilant to the incandescent bulb.

I appreciate that you guys have done your homework (I've purchased LEDs from you) - #1-3 is the same thing. Ceramic is an insulator, probably in the housing.

#5 is likely unobtanium. =)

@DrSpeed - Yes, the power consumption needs to be equivalent to the incandescent bulb. However, insulation, housing design, etc.. will ultimately play into just how how the resistor will get. @rt66er brings up another good point, which is something that we've done as well :)
Putting on my nerd hat....

Resistors in series:

R total = R1 + R2

In parallel:

1/R total = 1/R1 + 1/R2

Two 3 ohm's in parallel is an equivilant 1.5 ohm, no? You'd need two 12 ohm resistors to have the equivilant 6 phms....
