LED resistor question

Hello all! I’m new to this forum and looking for a quick answer to my question. Im just now starting to put some work/slight modification into our 2008 sequoia. We’ve had it for a while and I figured it’s time to freshen it up. I have plenty of experience working on cars, and have had my fair share of lighting upgrades in several other vehicles. This however, is the first time I will be installing the resistors. What I have are 4 led’s, 2 switchback turn signals for the front, 2 amber for the back. I also have 4 50w6ohm resistors. My question is, do I need to install one resistor per led turn signal? Somebody asked this question but it never got answered and I don’t want to bump an old thread. Any help is appreciated!

 

Welcome to the Forum!

There's a 2ND gen sequioa thread here. Link.

I would imagine that as long as its on the circuit, and is the correct resistance that it wouldn't need one at every light.

I've asked this question before, and never got a response either.

 

You might get away with just two, one for each side. I'm not sure about that at all, but I say so because, when I replaced my front headlights, DRLs, and turn signals for 2018 Sequoia LED clusters, there was no hyperflash on the turn signals. But when I also replaced the bulbs in the back with LEDs, I got the hyperflash and had to install the resistors in the back. So all I'm using is one for each side.

 

So far it sounds like it’ll be trial and error. I was planning to do all 4, but if two work, then that’s a win!

 

Hey yall, I went ahead and installed my front switchback leds with the resistors. Only thing thats weird, is they are always orange with the truck running unless the headlights are switched on. I thought they would stay white at all times besides turn signals, regardless, its not a big deal just found it odd. Anyways, the resistors get burning hot! Only when the engine is running though. When the ignition is off and I have parking lights on, they are white, and resistors are cool. Is this going to be an issue? Considering the drls are ALWAYS on if the engine is running. I understand they are going to get hot, just wondering if it will be problematic with them always in orange mode with drls on.

 

Also here is a pic of where i mounted them. To the frame for max heat dissapation

 

Final update for this thread! Did a bunch of experimenting and found several answers and encountered several problems along the way.
Question #1. How many resistors do I need if installing 4 led turn signals?
Answer: One per each turn signal. I used 4 50w6ohm resistors
Question #2. My switchbacks stay orange when the engine is running and even when the parking lights are on. Only white with the headlights on, or with parking lights on and engine off.
Answer: This is due to the flasher relay that we have and the drl function.
What I did: I depinned the THIN GREY wire on the flasher relay connector. It is pin #5. Theres a youtube video that lays it out for even the newbiest people like me sometimes. What this did was removed the drl feature, and allowed my parking lights to now operate the white part of the switchback leds. This was a BIG PROBLEM because when the drl’s were still functional, the resistors were getting power and working hard. They were reaching temps over 300° within minutes. Obviously this would not work and would end in a fire on one drive. So the drl bypass solved my overheating resistors, and my improper color switchback.
Lmk if you have any other questions! It’s not a bad job after all, just takes some research and some thinking.

 

If anyone sees this I need help. Both my resistors got super hot and killed themselves. How do I stop this from happening. Everything was working fine until I realized my high beams died. Then I realized I had dead resistors and my brake like would turn on instead of high beams.
