How to Fix AlphaRex Hyperflash Issue

[@derekrickson7314]

Second gen Tacoma owner. Love these AlphaRex headlights. Hyper-flash issue drove me nuts. Reached out to TacomaBeast and they sent me a pair of resisters. Watched this video and the issue was resolved in less than 20 minutes. Thanks for a quick and easy fix Zach!

[@SunshineStateVikings]

No problem! Thanks for leaving a comment like yours, it lets us know we are doing a good job and helps motivate us to keep trying to make useful content like that! ✌️😃 enjoy the lights we still love ours.

[@basselmourra6603]

Hey man I have the same issue and I need the resistor. How can I order them from Tacoma beast?

[@TheUtahMan]

Saw this video too late. I had the same issue, contacted alpha Rex about it and they never got back to me. The hyper flash drove me so nuts I stopped using my turn signals all together because it was a constant reminder that my $1000 headlights weren’t working properly lol. Sold the truck a few weeks ago. Thanks for sharing this. Now I won’t hesitate buying alpharex again, loved them.

[@SunshineStateVikings]

Oh no! So sorry to hear about your experience, your story is one of the many reasons we try to make content like this. We simply want to help others with information we have learned ourselves!

[@rudycornelius5119]

Yo im doing the same thing your doing! But i still got the truck. Got mine from the retrofit guys and i ask if they can send me the resistors and they said its not going to fix it. But this guy is doin it and it fix it! I dunno man.

[@mvincent7704]

Thanks for the video, I just replaced mine on my 2010 Tacoma, and your video made it easy. Do you have any idea how long these resistors last?

[@juniorsarmiento7292]

I had hyperflash happen months after I installed headlight/resistor in my Tundra. Do you think the resistors went out?

[@joseg.5937]

You would think that for $1200 the company would figure it out so you would have any issues.

[@paint3ball]

Just installed mine and got the hyperflash issue on the drivers side. Waited 65 days to get them and then this. They are sick looking but this shouldn’t happen…

[@BROKExx]

not to mention their customer service is fucking awful

[@Coloradoboss]

I asked alpharex if I could install resistors on my headlights for my Rav4 and they told me not to install resistors, this is interesting. I bought mine from a 3rd party vendor on ebay. I may be SOL. Thanks for the video though. Wish I saw it sooner.

[@garrettschaible5865]

very helpful, originally hooked up wires just to drls so had hyperflash at night. its fixed now 😊

[@SunshineStateVikings]

Awesome, we are happy our video was able to help!

[@compassandradio6261]

What's cool is that your Tacoma already has faux vents next to its headlights. Now, they can actually be functional to keep your resistors cool.

[@ryanfloberg5601]

Thank you, worked!

[@zachgobonkers]

I just got the pros installed on mine which uses halogen low beams. I’m about to replace them with LED bulbs. Will this cause the hyper flash problem?

[@SunshineStateVikings]

It should only be possible if the turn signals are being changed out to LED. If it’s just the low beam it I don’t believe it will affect it.

[@isaiahiniguez5631]

What LED bulbs did you end up swapping with??

[@azballerguy]

I have a 11 Tacoma with the factory DRL and the 12-15 front conversion. I already have the alpha Rex tails. Curious to see if I will have hyper flashing or not when I get my headlights

[@scorpionyted3283]

Did you have the issue or they already fix it?!!!

Hi there, I am recently just installed these onto my 2013 Tacoma, and I don't get my DRL's or turnsignals. Everything else seems to run properly. I am have some contact with Alpharex, but nothing has been resolved yet. Do you have any advice? Feeling bummed they are not working properly.

[@AlRoque-hy5td]

I have the same hyper flash issues. I contacted the seller who pointed me to alphare. I contacted alpharex but having difficulties obtaining support/ just spinning my wheels. Can you advise who to contact to obtain the resistor to fix my hyperflash issues?

[@christianbarcinas694]

Can you please send me the link to where you bought the resistor? I’m having the same issue.

[@ramiroramirez8535]

Intael everything as you show in the video, but now it doesn't start, my tacoma is a 2008 model, do you have a solution, thank you

You going to be at Expo East?

[@reeseotero6619]

Thank you for this video brotha.

[@SunshineStateVikings]

Glad you found this video valuable 😊

[@jaimebakal4253]

What year is your Tacoma? I just installed the same headlights to my 2015 Tacoma Limited and I didn't have the hyper flashing turn signal, because I have a led bulb on my rear turn signal which I have installed the resistors for that reason 😅 maybe since they are powered by the same line that's why I didn't have that issue when I installed my Alpharex NOVA Series.

[@SunshineStateVikings]

Loki is a 2014 TRD Off-road, we’ve been getting a lot of mixed reports of others either getting hyper flash or not with a variety of situations. Some have had it just installing the tail lights and some have had no issues at all with the same headlights and taillights installed just like us. From what we gather and based off talks with AlphaRex customer support it’s just random as to wether or not it will happen between the product and the truck itself. But either way it’s awesome to hear about your experience and that you didn’t have to hassle with the resistors for your install, it wasn’t bad to do just another step and added stuff is all. Thanks for sharing!

[@Th33Oth3rGuy]

On your 2015 tacoma can u turn off the DRL with your switch or does it constantly stay on ?

[@jaimebakal4253]

@@Th33Oth3rGuy unfortunately the DRL switch is disabled so the surrounding light is constantly on. Other than that it’s all good 👍 I love my alpha rex light 😀

[@Th33Oth3rGuy]

For your Tacoma when you turn the switch to the off position does your DRL turn off or constantly stay on? Because mine stays on

[@SunshineStateVikings]

The AlphaRex DRLs stay on all the time. We just resolved this issue by installing an electronics manager and will have a video come out in the next few weeks that will go into it a little further!

[@marvinj1972]

Great video. I currently have a similar problem on my F-150 Alpha Rex send me a pair of harnesses and supposedly should solve the issue, but it didn't work, yet they sent me a new set of headlights, but the issue persists. Do you think I have the same problem you had?!

[@carystarke8000]

I sure hope that I have that already when I bought the Headlights , it comes with 1 DRL Converter , and you buy a pair of Converter Harness kit . I'm guessing maybe of those 3 black boxes , 1 is a resistor >?

[@craigpattison5762]

Can you provide the part number of the provided resistors and confirm what their resistance is? I thought you said they were 100 ohm which sounds pretty high as I've heard others that had to install resistors on their LED headlights only needed 5 to 6 ohm resistors.

[@SunshineStateVikings]

We are currently away from home but as soon as we get back we can confirm that for you. They are definitely 100 ohm from I remember. I also am not sure if they sell it. All we had to do was let them know we had the issue and they sent them out to us

[@craigpattison5762]

@@SunshineStateVikings hi, any luck finding out the specific model/ohm of resistors you used? Thx!

[@josemercado8496]

Does one resistor fix the headlight and taillight? Or do you need a resistor for the front and another for the back?

[@delgado3033]

It would fix both bc that’s the only reason your taillight is hyper flashing bc the front one is doing it as soon as you fix the front one it should control the back one

[@johnlocus3096]

in my case, i had both alpharex headlights and tail lights, had hyperflash. They sent me resistors and told me to put them on the tail lights, problem fixed. so i guess adding the resistors on either or works fine 👍(this may or may not be right but I think if you have oem tail lights and you install alpharex headlights you wont have hyper flash issue because there is already resistors built onto the headlight)

[@SunshineStateVikings]

That’s interesting, it really seems like hit or miss with this issue. Just recently talked to another individual asking about some other options he found to fix the problem as he wanted to be able to correct them during the initial install. had same situation as you, he installed both new AlphaRex headlights and tail lights however he ended up not even having the problem with either one. I’m sure this is why they don’t just send the resistors initially with the product, they likely only have some that experience the problem and have no way to tell which sets will experience it. Maybe it’s all situational.

[@artoli7054]

Do you know what kind of resistors they sent you? How many watt and ohms?

[@SunshineStateVikings]

@@artoli7054 they are un-branded but they are for sure 10 ohm resistors (one for each side)

[@joseelizondo7535]

Hey I have alpharex headlights and they have resistors already and the passenger side has hyperflash any tips to find the issue?

[@alvarosolano6569]

Great info 👍🏽

[@taximaroa]

hello, the hyper flash happens on the driverside for me. Do i just tap it in the same wires you did but on the drivers side?

[@SunshineStateVikings]

Yes, that is all that should need to happen. Just be sure to confirm that your wires your about to tap are the turn signal leads just like we showed in the video, you are merely adding resistance to that circuit so your computer thinks the incandescent bulb is still there. Hope this helps, and feel free to ask any other questions you might have!

[@loganhopkins7133]

Having the same hyperflash issue, do you know what size resistor you used?

[@scorpionyted3283]

Did you findout?

[@miya7525]

Is this only an older car thing? I have a 2023 4runner with this issue and I’m in the middle of communicating with Alpharex and they don’t think this is the issue

[@josemrubio442]

Thx I needed this vid.

[@SunshineStateVikings]

Glad you found it, and hope it helped!

[@alfredopeliajr.9229]

I had the same issue, make sure all the prongs in the male end of the plugs are straight and not bent. My issue was one of the prongs were bent and not going into the female end correctly making the turn signal to hyperflash. I zoomed in to the video and it kinda looked like one of the prongs were bent

[@joseelizondo7535]

Do you mean that the harness is actually plugged in correctly? I'm having hyperflash when my turn signal is on but they already have resistors and it's only on the passenger turn signal

[@alfredopeliajr.9229]

In my case, one of the metal prongs in the headlight plug was bent over, not going into the holes making the headlight hyperflash. Just look inside the plug and make sure all of the metal prongs go into the holes in the wiring correctly. I did not use a resistor.

[@joseelizondo7535]

@@alfredopeliajr.9229 ok I'll check that cause mine have already resistors attached to the headlights and only the passenger side will hyperflash when turn signal is on

[@GoldenBoy0423]

I just installed the resisters is not hyper flashing in the cab but the actual headlights are flashing the turn signal

[@PlayCallOfDutyMW3]

If you have LED turn signals on front and rear you can get rid of the resistors and replace your turn signal flasher relay with a LED specific one. More streamline, no worry of resistors burning up, bad connections, and lower voltage consumption. Just a different way of correcting hyper flash.

[@SunshineStateVikings]

Thank you for probably the most explained version of the relay fix we have ever received. We will look into that for sure to help guide others with that info as well in the future!

[@cameroneshleman4833]

What size are the resistors, I can't find the alpha rex ones anywhere

[@scorpionyted3283]

Did you find out??

[@tanercomertoglu5236]

Do your drl stay on after locking the truck?

[@SunshineStateVikings]

For a short time yes, I believe the intention is to leave some light on the ground for walking away Convenience.

[@kaomoua1998]

Does adding 1 resistor fix all hyperflash? Or they go individually to each one that has hyoerflash?

[@SunshineStateVikings]

Each light will get its own resistor, it’s basically to look like the bulb for each side

[@cheaterrico1652]

where do I exactly buy the resistors for my truck?

[@SunshineStateVikings]

We recommend reaching out directly to AlphaRex!

[@lingmorales7060]

i have the same problem with my lights what is that called to fix

[@craigpattison5762]

Wouldn't replacing the flasher with an LED flasher be an easier fix for the hyper-flash?

[@rockyhedding7117]

It would normally, but the wiring in the later 2nd gens 2012-2015 is way different. If you change the relay the front light will not flash at all.

[@justifiedbyfaith8971]

The 2nd gen with DRL's have an 18pin box that controls the flashing. It doesn't even use a standard type flasher relay.

[@stevepark1930]

my headlights came with a resistor but it only plugged into the drivers side harness, the pass harness had the same plug, (the yellow one in this video without a wire connected) but nothing to plug it into. my pass side blinker is the one that hyper flashes, only sometimes, like 50% of the time. you would think this would not be an issue at all at this point considering I bought the lights in 2024. WTF.

[@farmermike9262]

Thanks

[@pinpin891]

I installed one in my 2014 it was plug and play for me only thing you have to make sure you do is do not install anything in the fuse box in the engine bay install like this guy did in the fuse box next to the steering wheel

[@SunshineStateVikings]

We are happy it all went well for you!

[@mlapl03]

Why not install in fuse box in engine bay?

[@justifiedbyfaith8971]

@@mlapl03 because the fuse in the engine bay is tied to the evap system which momentarily turns on while the truck is off. You may see the lights come on during the night or odd times during the day. It also causes the DRL's to flicker during your engine start/crank which could potentially lower the life span of the LEDs.

[@aharonvazquez3646]

@@justifiedbyfaith8971 so would it just be better to not put that in or in some other place

[@justifiedbyfaith8971]

@@aharonvazquez3646 The Alpharex DRL and turn signals require the control box to function. You just want to run a wire from inside the cab to the engine bay instead of using the fuse tap inside the engine bay fuse box. Take note that you will need to cut the fuse tap and add on some wire to extend it. 1. Starting at the fuse tap, Cut off about 8" from the fuse tap and wire. 2. Solder an additional 3-4' of 16-18ga wire. 3. Plug the fuse tap into the fuse box inside the cab that is left of the steering wheel. 4. Run the new wire through the firewall. There are 2 grommets in the engine bay firewall that gives you access to the cabin. The top one has interior carpet trim that prevents you from just feeding the wire through. If you take a slim screw driver, you can shove it through. Tape the wire to the screw driver with electrical tape tightly and pull the screw driver back out. This will fish the wire into the engine bay for you. 5. Strip both ends of the old wire and the new wire and use a butt connector or male/female quick disconnects to connect the wires back. The fuse that you can tap into is the radio fuse.

[@mikedougherty9361]

Did you ever find the part number to the resistor kit need for the headlights? Having the same issue with mine

[@SunshineStateVikings]

I did! The package is actually a 2 piece set of 10 ohm resistors. The O in ohm is too close to the 10 so I read it as 100 ohm. They are in fact 10 OHM resistors. Part number listed on the package is just as follows AHL-LR-10OHM-2PC There is nothing listed physically on the actual resistors. If you have an alpha Rex product, I recommend giving them a call as I don’t think they have it on their site for sell. They will either send them to you for free or I think can send them for I think $15 if they weren’t the original seller to you. I hope this info finds you well and helps you fix your issue!
