LED Rear turn signal questions

[rolo06]

Long time lurker, first time posting.

I have a 2006 4Runner Limited. I have purchased the VLEDS triton amber amber for the front turn signals and DRLs. the questions i have are regarding the rear turn signals, i am planing in purchasing these HIGH-VIS AMBER 21 LED 7443 7440 STANDARD BASE | 1 PAIR. now the questions i have not been able to have found an answer for are:
1) will the rear turn signals in our 4runners will also need resistor given that 6 ohm resistors will be installed for the front VLEDS triton.

(2) how many resistors do we need in our 4runners. do each turn signals needs its own resistor (6 or 3 ohm). and if only two needed, do they have to be installed front or back or it doesn’t matter.

3) any good instructions for rear led installs i have been in contact for J.A through his website but since he himself has not switch the rears to led has not been able to guide me.

note: have looked into replacing the relay but have been unable to since i believe that my relay controls both the turn signals and drls. thus have to stick with resistors

your guidance and advice will be appreciated,

man... i have been stuck on this as well.. I'm modifying the flasher but don't know what resistor to use, i have used .01, 1 watt works but will burn out after a while when u use the hazards, wondering how high up of a wattage should i go...

I also have the Triton switchbacks up front. I've been wanting to install rear LED turn signals, but when (if)I do, I'll be ponying up for vLed V3 turn signal (pricey). Those kits, like the switchback kit, already come with built in resistors. Hence why those pricey kits are expensive. (not just b/c they have the resistors, but generally are of high quality)

Rule of thumb I've seen: Every bulb you replace with an LED, you must use a resistor.

hope this helps

that is, unless the LED assembly (bulb) already has the correct resistor built into it.

seems like more and more nowdays come with resistors installed so that one doesnt have to worry about correcting this externally, no?

100% agree. It always seemed strange to me when I see these "plug & play" LED bulbs come with no resistor. SML . It's even funnier to see some teenagers run around with them and see their turn signals hyper flash while they blast their music.............

i think the best one was when LEDs first started coming out. guys would swap out their bulbs for an LED bulb that was basically 15 5mm leds facing forward...absolutely no light beyond like 10*. i would see a brake light that went from a 5" circle and well lit to a tiny 1" circle that was actually dimmer than the OEM brake light...i just shook my head....

 

[hunterD1]

does any body know what resistor to use for the flasher relay?

 

[yosh2000]

what bulbs did you purchase. from my understanding, any decent bulb nowadays should come with internal resistance to not have to worry about adding separate resistors. the linked LED bulbs the OP linked show an operating voltage of 14.5v, which should work no problem.

 

[hunterD1]

these have no resistors...leds all around, so last resort is modify the flasher

 

[yosh2000]

since they are TRS bulbs, why not make a call into them and ask how to make them work?

straigtht form the source, "The XB LED bulbs are can-bus friendly and should not hyper flash or cause any "lamp out" errors in MOST applications. If however your vehicle requires more resistance, we recommend using the Morimoto HD Load Resistors" ...http://www.theretrofitsource.com/components/harnesses/morimoto-hd-load-resistors.html#.VT5pCSFVhBc

 

[hunterD1]

yeah they said to add those but i don't want more shit hangin on the housing, plus they get super hot, and don't want stuff melting

 

[yosh2000]

they gave you a solution...what more do you want?!

the reason they get hot is the very same reason your current resistors are blowing. waste energy is converted to heat.

 

[hunterD1]

all i asked for is the resistor size and wattage.. so i can modify my flasher relay that's all buddy.

 

[yosh2000]

And I, and TRS, gave you your solution, plus a bonus answer as to the reasoning being the suggestions.

If you're still looking for the resister, here is your answer:

R= V / I

Yosh is right. With that particular product, seems like the only (clean) way to make it work is the additional resistors they sell. Otherwise, you might want to look at another product.

If you get them to work, post pics!

Update Research

After browsing through the toyotanation forums i came accross the following:

"The reason I say a set as front and back is because you would never convert just a left or a right side to LED and leave the other side alone.

People might only do the front bulbs or the back bulbs if they choose. For people like that you would need to install a 6ohm resistor next to each LED you installed whether it's the back or the front.

People who choose to install 4 LED bulbs like myself, only need to use 2 3ohm resistors. Where you put the doesn't matter as long as you have one for the left side and one for the right side."http://www.toyotanation.com/forum/310-7th-generation-2012/475337-2013-camry-turn-signal-flasher.html

so from reading the replies in that forum i can conclude that if replacing all turn signals in my 06 4runner limited i can just purchased the two 3ohm resistors from VLEDS and install them in the front(due to space constraint in the back and heat dissipation issues) one on each side. Correct me if wrong.
