LED hyper flash problem

I installed front switchback turn signal light on my 17 tundra CM n looking around for a relay or plugs n play resistor without splicing the wire.

 

It’s a 6ohm resister and I think vleds has the only plug n play. Other then that you will have to at least use the cheap pinch tap style connectors.

 

I saw the vleds n that my next option to do but there 2 kinds they offer.

 

I’m running VLED Triton V6 bulbs up front with 3ohm pnp resistor. In the rear I’m running another brand led no resistor there since I’m running 3ohm up front. If your rear are holegen then you need 6ohm resistors. Hope that makes sense. I highly recommend VLED products.

 

What the difference on both 3 n 6 ohm resistor. I see most ppls using the 6ohms

 

I answered your question on my post. Re-read it please.

 

Oh ok sorry gotcha

 

Let us know if you need anything else. If ever I doubt give vled a call. They are very knowledgeable and helpful.

 

Ok thanks

 

Howdy, just to make sure I am looking at this correctly and since we have the same truck basically...I installed the '18 OEM LED headlights and fogs. Now, I want to order the markers, brake and turn signals from VLEDs (cargo, backup, license plate and all internal are already VLEDs); my puddle lights are LED too.

Since there doesn't seem to be a LED flasher option for the Tundra that I can find, I like the plug in VLR resisters for the V6 Triton Amber 3157CK for the front turn signals and the 921 Red HVR6 for the rear turn signals. The V6 Triton order page only shows a VLR6 option with the plug in cable, and their details about when to use 3ohm vs 6ohm focuses on whether the front and back are on the single fuse per side (which I don't know for sure but would assume so based on your comments).

In your setup, you are using the VLR3 on each side plugged into the front turn signals and no resister in the back, correct? Ultimately, if this works, I would not have to splice wires with the plug in VLR pack connected to the front and potentially save $$ by only needing two VLR3 packs (one on each front headlight with the V6 Triton) and then HVR6 LEDs in the back. Is my direction correct? With the information on the VLED web site, I think I have the rest figured out.

 

Correct.. 3ohm resistor in the front works for both front and rear. you will be fine.. dont worry =D

Got some more VLEDs today to finish replacing the halogens. I did not go with the Triton V6, but am using their High Visibility Amber and Red in the appropriate locations and VLR-3 resisters in the back. After talking with the VLEDs guys, they said I would be fine using the HVA 3157CK LED in the front turns since my front ambers are only used as turn signals (Platinum version). If the amber front turns were also used as DRL, then I would need to use the Triton V6. So I got the HVA 3157CK 6 LED Amber for the Front Turns, HVR 3157CK 6 LED Red for the rear brake, 194 single LED Amber for Front Markers and HVR 921 6 LED Red for Rear Turns and 3rd brake. These should all be brighter than the halogen and will all use the stock OEM sockets.

 

Changed all of the rest of the halogens for VLEDS today. Everything went fine except for the front turns...HVA 3157CK 6 LED Amber for the Front Turns didn't work in my 2018 LED headlight housing. The original yellow bulb is deeper and straighter than the 3157CK; it looks more like a 7443 or 7440. I read somewhere that this is really a 7444a or standard vs. CK. Does anyone know the correct bulb type? The guide on VLEDS' web site says it should be a 3157CK Amber.

 

I got 3157 switchback led. Idk if the 2018 is the same

 

1. 3156CK Only works for the 18 housings if you are using Triton VLED bulbs. Since you are using regular bulbs I believe it should be 7440 but don’t recall if there is a letter after that.

 

Took the bulb out and followed VLEDS help page to determine whether it is CK or Standard...the 2018 bulb is 7444NA with a Standard socket...Got my old 2016 Platinum headlights down and they are the 3157CK for sure. Thanks for responding...

 

Got my replacement front turn signal from VLEDS, 7443N (7444NA, 7440) and completed the LED conversion. Now, everything is LED

 

Chuck thank you for posting this, I am installing 2018 headlights in my 2015, and i would like to switch to LED turn signals (former 2015 amber DTRL have been de-pinned at the relay in the cab). Can you confirm the set up for the front? VLEDS, "amber 7443" and two 3 ohm resistors to splice into the signal wires?
(i have VLED signal in rear with 3 ohm resistors back there as well)

Since I have a 2016 Platinum that used a single LED for DRL, I did not have to do anything in the cab - my amber lamps in front are turn signal only. I have one VLR-3 (3 ohm) resistor in the back on each side only (none in front); One HVR 921 6 LED Red for each Rear Turn and one 7443N (7444NA, 7440) Amber for each Front Turn.

According to VLEDS, one 3 ohm resistor for each side when changing both bulbs to LED; One 6 ohm resister for each side when changing only on bulb each side to LED. Because I was changing all 4 front and rear turn signal bulbs to LED all at once, I used the fitment for 4 LED CONFIGURATION in the Load Resistor Guide (3 ohm resistor for each side).

VLEDS explains it here: http://www.vleds.com/shop-products/vlr-resistors/turn-signal-resistors.html
VLEDS Load Resistor Guide: http://www.vleds.com/hyper-flash-fix-load-resistors/

I would think that you only need the amber 7443 LEDs. With already having 3 ohm resistors in the back, no more should be needed.

 

Correct. 1x 3ohm per side. I have the same setup and leds on both ends.

 

good catch, thanks guys both of you. parts ordered.

 

I consulted with @BlueBottle during my upgrade as you can probably tell! We both have '16 Platinums...

 

So what I am gathering is the front and rear bulbs are parallel circuits so an led bulb, 6 ohm resister up front and normal bulbs (6 ohm bulb resistance) in back have a parallel resistance of 3 ohms. So the circuit only requires 3 ohms to load properly and flash normal. So when using all leds front and rear the 50watt 3 ohm is all that is required for the circuit to load and flash normally. (Per side)

 

Yes exactly. That’s what I’m running.

 

just wanted to follow up, the VLED 7443 signal bulb you guys recommended for the 2018 housing is great. I am running 6 ohm only on each rear and do not have hyper-flash. Also have triton leds in rear and turn signal mirrors, somehow there is enough load. I bought the 3 ohm pair but didnt end up having to use them.

 

I have a cheaper switchback 3157ck bulb (headlights) i bought from Amazon and used 6 ohm resistors. I’m still getting hyperflash. I have spyder led taillights so I should get 3ohm resistors for them?

 

Well, 2 things, still having hyperflash, and you are using led in front and rear, are you sure you have the 3 ohm across the correct 2 wires?
And, if they are what you can do before spending the $ on the 6ohm is to take the 3 ohm off the other side and stack the resistors example why/blk wire- 3ohm-3ohm-red wire. So you can get a 6 ohm load on one side. Then check the one side for hyperflash. if it works then you can get the 6ohms and put them in place. If it is still hyperflashing, I would go back to my first question. Are you connected to the right wires. If the resistance is in line with the parking lights and not the flashers it will not make a noticeable difference.

 

if you have a 6 ohm in there you will be fine. A 3 ohm will be fine too. You have a little more impedance in the circuit. Which is fine for the flasher.

 

Based on my experience and information discussed in thread #20 above, if both front and back are LEDs, then 3 ohm resistors are appropriate; if either front or back, but not both are LEDs, then 6 ohm resistors is appropriate.

I replaced both front and rear with LEDs and used 3 ohm resistors which worked fine.

I agree with Alptbird that you can stack the resistors to troubleshoot this.
