LED Flasher Relay
- Thread starter Sahara01
- Start date
I believe all 2000-2006 use the LM470. The flasher module won’t change which bulbs work, but will change the operation of the entire system. Since the other bulbs work fine, we can generally assume the flasher is not the issue.
The issue with the side marker bulbs not working is because the sidemarkers are designed to ground through the filament of the front turn signal bulb. Since that bulb is now LED, not enough current can flow to light either bulb, assuming both the sidemarker and the turn signal bulbs are LED.
By the way, the resistor diagram I linked only works if the sidemarker bulb is also converted to LED. A halogen sidemarker would require a much higher wattage and lower resistance resistor.

The EP26 will still allow most of the functionality but will change some of the operating characteristics in the later year TJs. For example, the turn signals will operate even with no keys in. Better to use the correct flasher for the year.
You can confirm the LM470 part number by looking up the flasher relay on RockAuto or various auto parts store websites
I've tried everything to get mine to work. I've followed this thread and still nothing. I'm thinking it is a ground? Can anyone help? I've got all lights except for passenger fender signal. But when I turn flashers on the front passenger signal stops and the fender passenger blinks. I have an LED light bar installed that's it. No led taillights nor headlights. Some input would be greatly appreciated. Also I've tried the LM470 it blows fuses.
So about a year ago I replaced rear lights, head lights to led with a new relay. All was well until I replaced front signals to led switchback and side markers to led.
I lived with hyper flashing In the dash and the side markers didn’t blink for a few months and then I started getting the beeping now and then.
Went to diode dynamics website and they recommended the inline resistors, as diD a few people in this forum. I thought it was going to be a big hassle.
I just finished putting them in on the front switchback flashers, all is well so far. I instantly noticed no hyper flashing in the dash and the side markers are working again. Also no beeping so far. I think it’s fixed for good!

Hello all, just as confirmation and for future reference the LM470 worked fine on my TJ 2002.
I installed first the EP27 but the hazards didn't work.

There seemed to be a lot of confusion on this thread.
So the EP26 is 97-00 and the EP 27 is 01-06?
I have a 1997 and Just put in the EP26. Seems to be working fine.

Is that the same as the this one? https://wranglertjforum.com/threads/led-flasher-relay.11733/#post-185489

So I just snagged an EP27, fixed hyper flashing when using my turn signals, but super hyper flashes for my hazards. Guessing this is what you are getting at by they won’t function the same as stock?
That’s how mine always were. They functioned but they were always a bit quicker than factory.
Interesting. I swapped back in the factory relay and I noticed as I drove to work this morning that the speed of the blinker flash varied. One turn it would be faster than the OEM lights, but the next it would be the same speed, as if it was naturally fluctuating.
As of now the OEM relay works for hazards/blinkers, whereas the EP27 made me lose hazard functionality.
I’m going to buy the novita lm470 later and see how that works.
On my '98 Sahara,
I am replacing the OEM front fenders with EAG fenders.
EAG uses the Eagle Eye LED for turn signals
and no side marker lamps.
The rear lights will remain OEM incandescent bulbs.
So I want to thank everyone for all of your input
but I would just like to confirm my understanding.
I should get the EP26 like this one:
EP26 on Amazon

Update: I decided to leave the OEM relay in, and it appears that I no longer have experienced hyper flashing like I had with the EP27. Originally, when I didn't make a distinct position change to turn, as there is some "slop" in the turn signal lever, I did notice hyper flashing. However, even when I have tried repeating this over the past few weeks I no longer experience hyper flash. I don't know if they relay or whichever governing logic is able to teach itself to new conditions or what, but apparently I have gotten away without changing to the EP27 or lm470.

I am fairly certain this is correct, based off what other people have said both in this forum, on youtube videos, or other forums. You could always be certain by taking out your relay and seeing if it in fact has 4 pins. Mine being an 03 had 5, so I needed the EP27, but even with that I still had issues. Honestly it is hard to say what the exact correct relay is. In my case the EP27 fixed my turn signal hyper flash but made the hazards go from working fine to extreme hyper flash. Now I experience no hyper flash with the OEM relay, which I find odd. There is a chance I had a bad EP27, which other people have dealt with and took several trips to the auto store to get a different EP27 until it worked. It is luck of the draw.
In conclusion, your best bet is to try that EP26 and see if it works. It is trial and error from what I have read and experienced myself. Give an update with what you find. Good Luck!
