    I've been looking into swapping my turn signal bulbs over to LED's before coming across this thread; I just finished doing this on my 2019 and man what a difference! Thank you @thomasbus337

    The problem is with the trucks equipped with LED headlights. When the headlights are on, oncoming cars can't see the turn signal because the headlights overtake the dim amber turn. I replaced mine with an led and it seems to be bright enough now. I may the the wire switch when feeling motivated one of these days!

    I also swapped in some led bulbs but am wondering how much brighter they will be if we switch the wires? Thought I saw someone say it was minimal but i'm not sure.

    I guess mine look good because I have the standard headlights (sorry, name escapes me right now) and I have no plans to swap them to LEDs.

    Won't make a difference, same voltage, it's the filaments in the bulbs that are 8w or 28w, led is getting same 12v power regardless.

    I replaced mine with LEDs a while back before this mod "hack correction" came out. I like my LED it matches my LED head lamps and LED fogs, all LED. :D

    I wouldn't change it, I can see the blinker reflecting off street signs across 4 lane traffic.

    Yeah, if you’ve already upgraded to LED then this wiring change won’t be needed

    I find that sticking my arm out the window of my two year old truck and pointing towards the direction in which I intend to turn helps as well.. :rofl:
    But seriously.. will do this mod as well. Thanks for the info!

    Just a note for anyone repinning their turn signal. If you get an NSV lightbar, your going to have to return your factory turn light plug wiring back to original, then rewire the NSV plug that T's into your factory headlight plug, removing the blue wire and shifting the center wire to the outside hole again to use the 28w filament. This is for 2014-2019 with DRL & LED. I was blowing 10A tail light fuse, no DRL, no motor, no side lights till I figured it out.

    I'll add to that, that their instructions call out 2014-19 DRL LED you have to cut the blue wire at the turn signal plug, anyone that has shifted pins because of weak turn signals will need to do this, can't speak to every model tundra. Other than the blue wire gets cut or unpinned.

    Working on it!
    Yep, did mine a minute ago - took about an hour. I don't have the smallest hands, so had to make some room. On the pax side, I removed the three bolts holding the windshield washer reservoir and slid it back a bit. On the driver's side, I loosened the battery hold down and slid it to the left. The reason it took me an hour was I'd reinstalled the pax side and looked on top of my tool box and saw the white plastic lock, so after some choice words, I had backtrack a bit. Worth the time and the few cuss words...Thanks to the OP.

    [An removal-install note for the rubber butt plug on the connector - I found it super simple to use the smallest jeweler's screwdriver, enter the EMPTY socket hole from the connector face and push the rubber plug out (better than trying to flip it out from the back and throwing it across the engine) and on the reinstall, BEFORE you move the pin to the outboard end of the plug, put the rubber plug back into the connector, then reinstall the pin. I found it to give me a bit more room...and didn't drop the damn thing.]

    Did mine the other day just like you GREEN. unmount the washer fluid and slid the battery over. Now they're bright like my '14 was.

    Great info. Thanks. This was probably one of my most unhappy tundra moments. knowing I'm using my directional & no one knew I was trying to turn. 1st problem that had to be fixed. (I'm not goin to get into the " premium sound system "") LoL... Thank you! even tho I had previously installed the LED's. Great post....

    Although cool to fiddle around with, swapping the wire on a '19 SR makes them dimmer...

    [Off topic] Just installed OEM fog lights, and aside from the fog harnesses pre-wired, I saw two other harnesses/plugs hanging loose behind bumper. Any ideas? Parking sensor?

    Someone needs to figure out how the dim turn signals on certain models passed NHTSA tests and/or requirements!

    don't lights need to pass some visibility and brightness tests?
    How did Toyota get away with that if the lights are too dim?

    I guess we would also have to know who does the certification for the lights, is it the headlight manufacturer or Toyota? If the headlamp maker tests them off the truck using their own wiring setup then they will work properly. The problem is when they are mounted on the truck that has been using the same 3 pin plug and wiring configuration since 2014

    Dude. You are the man! Thank you so much for all this information, research and videos. I was reading it all and thought "oh wow, this is gonna be gnarly!" – I just finished doing the wire swap (15 minutes) and bam! I have bright front amber turn signals that people can actually see!

    I did mess up and leave the white clips out but took three minutes to go back in and re-install them.

    Thank you again. I am so grateful for this forum and people like you that help us all.

    I think I'm going to give this a try - I already have JDM Astar LEDs swapped in, but it looks like they're 2 stage bulbs, so I might be able to get a little more juice out of them with this mod. I'll give it a try tomorrow and report back.

    I think LEDs themselves appear brighter without the mod because they're getting installed in a reflective housing meant for halogens.. right?

    Just did the pin swap and it definitely appears to have helped with the Astar's, but it's hard to tell how much in the day time. Can't wait to blind some people at night now.

    Damnit... started getting hyperflash on the passenger side after driving around a bit. Not sure why it's only happening on one side... now I'm torn between swapping the pins back or putting the old halogen bulbs back. I might get resistors eventually.

    Well, one of my coworkers was confirmed with Covid last week. So we’re back to working from home until we can all go get tested. So I figured ide knock this out this morning. I have vled leds in the turn signals. I may notice an ever so slight increase in brightness when I compared one to the untouched other. But then again it’s hard to determine intensity in the daylight. Guess I’ll have to see how it looks at night.
