LED Lighting Conversion

Dang...no longer a sticky...this thread was golden and helped a lot of folks, what a shame...but do realize it diverged way too much...well at least I got on the forum just in time as this was the king of LED lights information and testing.

 

For the blinker lights, are some of them built with some kind of resistor or do they all need resistors installed? If you replace front and back is the resistor still needed? What happens if you do the full rear signal mod and the fast blinking? In my defense I went through 50 pages of this thread looking for answers first...

 

It’s trial and error. I ran all LED but still had issues even with just the front.

I should put all my stuff up for sale. Not going to use it.

 

That's a shame. I have all led up front and reverse led bulbs with zero issues. A little leery to mess with the rear lights. Seems like those are very hit and miss.

 

If you only do front signals (I did yesterday), resistors weren't needed, but I think as soon as you do rear AND front, then "I heard" resistors all around but I can't validate that without testing. I know the rear's for sure regardless. Here is the thread that has some links to good bulbs and info on the resistor issue you brought up (with links to resistors).

I have the same setup without issues. I think when you change the rear brake lights to LED you have to add resistors, however if you only do the front signals but don’t touch the rear brake lights, you’re ok. I don’t think the reverse LEDs have an affect on the system at all. However if you do front, then do rear brakes, the front will then start to hyperblibk and you may need resistors all around, rear brake for sure wth or without front blinkers.

 

I ran front led only for a time and got random hyper flash on the passenger side.

 

Oh man that sucks, I’ve had these for a bit now and never hyperflashed...this was a suggestion from anothe taco owner and there is a video of a taco owner in the reviews section if you ever want to give it another shot...

Those are the ones I have. It’s something with my truck.

When i swapped left to right the flash stayed on the right side.

 

Wait a minute here...you were the one that suggested these in the first place! So let me ask you this, how did you notice the hyper-flash, was your dashboard signal blinker blinking quicker than usual when you signaled? Or did you notice the light reflection at night was super fast?

 

I know. They worked fine for about 2 months. Then it started up.

Both the actual light and the signal in the cluster would fast blink.

Flip on blinker. Get 2-3 normal blinks then hyper flash. Only on passenger side.

I think it’s my truck. I really do. Possibly a funky or loose ground maybe or whatever. Others have done just fronts without issue.

 

I am curious if you had trouble after you added led to the rears. Also did you try using resistors up front without having led in the rear or had you already done the rears before the front hyperflash. Did you put resistors on all 4 corners as needed. Odd that you had no front issues for 2 months unless it happened after adding the rears. I don't believe I have seen anyone with hyperflash with resistors on all 4 signal harnesses.

 

I would be curious to hear the response to this as well...very good question. If its only on the passenger side, check the receptacle in which the pins would be seated when the bulb is inserted, make sure they aren't loose (I highly doubt this but doesn't hurt). But in all honesty, it may be a "fried" OEM resistor wherever the blinker relay is located within our dash, which means you may now need to compensate for that at the bulb location. This may mean a slightly higher resistance/ohms than usually suggested. For example, some go with 6 to 8 ohms, you may need 10-12 ohms (mayne more? trial and error unless you find the signal relay with the cooked resistor and de-code the resistor strips to figure out what it was). Since the resistance with the OEM relay is in series with what we would have added in the past, that means that thier resistance values are added together to increase resistance. I don't know what the OEM value was, but if it was 5ohms for example, then when everything was working fine and we would add 6ohms more from an Amazon purchase, it was really 11ohms that prevented hyper-blinking. You pretty much have very little resistance if it's still blinking which could be due to a "failing resistor" and/or natural resistivity from the wiring/harnesses, OEM cabling length etc..if it didn't blink at all, it's the bulb (burnt because of a completely failed resistor) and if it came on and stayed on, that means there is NO resistance at all...

 

Those LED pods I suspected were the same internally, where one was 3x the price of the other but output looked striking similar?

LED spectrum comparison:



Looks pretty identical to me.

 

Question on turn signals...

So this is basically the only thing I haven't yet switched to LED. So those of you that have switched them out.

Has anyone found some good ones with built-in resistors to avoid the hyper flash?

Found these here

If no to that question, what bulbs and resistors combo is everyone liking right now.

If I swap the front do I have to do the back as well right away even if I use restores?

I've read a few posts that seem like there is a little problem here when upgrading the turn signals to LED.

I just purchased the V3 @mesojdm ultimate mirror signals and sold my V2's. So I want a brighter front turn signal and one that matches the color of the new mirror signals.

Thanks in advance!

 

I have the V3 mirrors with the xspeed ambers. Pretty close. No hyperflash. No led in rears. No resistors needed with this setup.

 

You got a link to these lights boss??

UPDATE: These them??

Front by themselves okay without resistors. As soon as you touch the back, then you may have to put resistors all around. @commbubba19 is the expert on this matter. I learned a lot from his on this subject matter.

 

Ahhhh i see. That must have been the issue I read about then.

So Front turns signals only as LED are fine without resistors and won't HyperFlash, but as soon as rear's are swapped then HyperFlash is an issue and all require resistors? @commbubba19

 

Link to xspeed at bottom of page in "products discussed". My pic has v3 mirrors too. Amazon has a video in daytime in reviews for these.
