Front blinkers

I have the new 2018 headlights with pnp harness, and motor control. Question is if I change out the blinker bulbs to led switchbacks will I need to add resistors?

 

@iHacker

 

Yes

 

Yes LEDs need resistors to work properly as turn signal bulb. Just remember now is a 7444NA for 2018 LED Headlights

 

Just a reminder, make sure you get blinker bulbs for an 18, because the bulbs changed from 3157ck on the 14-17's to 7444 on the 18 Led headlights.

 

I have VLEDS nice kit easy hook up

 

I would recommend the LED turns, I have found the 2018 lights really outshine the turn signals and people don't see them very easily. Not the best idea on Toyotas part, nice bright LED's and a incandescent turn signal buried in the interior corner.

 

My truck came with the factory installed LED headlights and it did not need the resistors at least in the front turn signals, I have yet to do the rear blinkers but front ones did not need them. I'm assuming because it came with factory LED's and the wiring must be ready for them. I installed these lights from Amazon.

here's a pic of it.

 

will the 7443 switchbacks from the retro fit source work?

 

I have the HP24/7443 bulb will it fit?

 

I was curious about this as well,to get my 18 lights full led when i install them, vleds has none listed for the 18,says there the same as the 17

 

You have any pics of yours by chance?

 

Vleds too pricey for me, the retrofit source ones much more in my range

 

Yeah 7443 is xcompatible with 7444NA

 

@iHacker
Installed the 7443 switchbacks but they only function as turn signal and when I arm or disarm the truck.
Not sure why the white part of it doesn’t turn on. Is it cause the led headlights and harness?

 

Ohh wait a minute looking at your profile say your truck is a 2018 SR5, so you never had the Amber DRL signal, that’s why no white LEDs in your 7443 LED bulbs

 

What he said, ^^^, only the orange blinkers work on the 2018’s

 

No I haven’t! How do I do that? Also like to note that I have the nsv light bar on the way. Any of this going to affect that install?

 

I have the the new led 2018 head lights. Truck originally came with the drl lights with led strip on the bottom, I got the harness from ihacker for the install. Only wire that I moved was the one that went from #2 spot to #3 spot based on instructions.

 

Maybe this is possible but no one have shared something like this for Platinum/1794 before, your 2018 SR5 basically have the same wiring with a LED strip in the bottom. Maybe I’m not sure or saying this is the way to go but you could try with a jumper between violet wire and adding a terminal in the center MT spot in turn signals socket

 

Can you hook me up with the two terminals to put in the plugs and I’ll try the jumper.

 

I can but honestly not sure if go to work I been looking the 7443 bulb diagram but I don’t recommend it, may cause issues or popping fuses

 

Ok

 

@iHacker, i installed the NSV light bar and after the install the drivers side switchback function works white he lights on and orange when turnsignal engaged but not the passengers side? wondering what happened and if i could do something wiring wise to get the other one to work. im not good with the schematics but i can follow directions. lol.

 

Not sure about it but definitely is for the NSV bar t-harness you used in driver side, no experience with the NSV bar wiring but I guess you had to t-tap something to the side marker in driver side, is this correct?

And I guess this is only with first click of headlights switch, because that’s the only way to get 12V for the MT spot in turn signals

 

I did the jumper from the blue wire on the t harness to purple wire

 

Yes that’s why, doing same thing in the passenger side, a jumper from purple wire to the same blue wire location

 

I need a pin to put in the passenger side plug the cause that spot is empty in passenger side plug

 

I can do a jumper for passenger side and send it to you if you like, it’s gonna be a 2 piece wire can you measure the wire length needed to connect turn signal socket center MT spot to side maker
