Thank you all for the help. I have tried 3 ohm resistors,  1 ohm resistors and .5 ohm resistors with no luck. The only change when adding these were reduced brightness in the hyperflashing blinkers.  I am out of options and am probably going to end up selling the morimotos and getting some recon tail lights painted to get the look I want.  Again, thank you all for the suggestions .

If your looking to sell the morimotos, how much are you wanting?

If you add 1 ohm resistors in paralllel it should work. Resistance in parallel adds such that 1 ohm resistors will keep the numerator the same but keep adding one to the denominator.

My numbers are made up!  I don’t know specifics. Just rough examples

I don’t see how adding resistance in his case would help at all. In my head, he has too much resistance to begin with.  This if fully assuming the new tail lights have built in resistors already

Don’t forget the option to flash the BCM to disable the bulb out indicator. 

 

Ill be having it done pretty soon. 

So if you have this done, you can run LED's without the hyperflash?  Does it screw up if you have regular incandescent bulbs in?

I'm taking my truck in Friday for service and I've thought about having this done, just wasn't sure what all it entailed.

If you don't mind, what's the dealer charging you to do this?

Dealer I bought the truck from said $175. 

 

It disables the bulb out warning system (which is hyperflash). So the BCM no longer looks for a specific load on the circuit. So afterwards you could run whatever you want. 

 

Call and ask them what theyll charge you. I’m curious. I’ve read $50 online before. I’d like that price better.

When I get a chance to call and talk to him at the dealership I'll let you know what he quotes me.  I think their hourly is $120, he cut that in half for me once in my 2014 when I was trying to add carplay because he was curious to see if what I was doing would work too.

Hell, I’m good for an hours labor haha

 

i talked to 2 other dealers and they never called me back with a price. 

I'd definitely rather pay him $120 and keep everything OEM than go hacking harnesses adding resistors and stuff.

Any word if this BCM reflash will work? Running the Morimoto tails in my truck and still occasionally getting the hyperflash every once in a while. If flashing the BCM to disable the hyperflash is actually possible, I'm totally doing it.

I just dropped off my truck for this BCM flash. So we will see.....

I had some body shop stuff on there too, so probably be late this week before I get it back. 

 

I'm fully expecting a "Oh yea, we couldn't do it like i thought" type of deal.

Any luck with it afterwards!?

Picked it up yesterday. With a giant scratch on my tail gate!! 

 

They said in the end, they could not do it like they thought. Went from $175 to $300 to nothing. I’ll be adding resistors I guess.

Damn, i have the morimoto tails in my LT. Even with the resistors built in they still tend to hyperflash quite a bit and it's really annoying lol.

i just installed mine on my LT as well and am running into these issues as well, half the time they are fine then out of nowhere my right turn signal is hyper flashing, but my left side has given me no problems in the past few days of ownership.

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
