why is it that if we do the turn signal mod we can't use led turn signals in the front?

 

Something to do with the ground. You still can use LED's, Just your corners will not blink with the lights off. Use LED's In your corners too!

 

LED's are polarized...they only work one way. When you try to send power through the negative lead on an LED, nothing will happen. That's what you are doing with the turnsignal mod....sending power through the ground.

I'm trying to make this clear w/o me knowing the proper names and terminology... The incandescant bulbs work with the hot and ground going through either lead....it'll work no matter which wire is touched on + and which is touched on -....it'll work either way. LED's are much different...they only work one way. hot to +, ground to -. That's why the turnsignal mod wont work...because power is being given to the bulb from both sides depending on what position your headlight switch is in.

 

Shaner you beat me by 20 mins. lol

L.E.D. = Light emitting diode.

Diodes only allow the flow of current in one direction.

 

...of course, there's always the use of bipolar LEDs, which emit (usually, but not always, a different color) light when reverse-biased.

You can fabricate your own bipolar LED arrays -- every place that you have an LED in the array, add a second LED in parallel with the leads reversed; only one of the pair will light at any given time, but the effect is that the panel will light no matter which way you power it. Something like that would work in conjunction with the "turn signal mod".

 

eeek. all sounds complicated to me, hahaha

 

My leds work fine? hmmm

 

You mean to tell me you've got the turn signal mod and it functions as normal?

sorry motoman, negatory.

 

I have the Turn signal Mod and everybulb on my truck except 9007, H10 are LED now. The corner flashes fine when the lights are on and runs just fine. The Corner just doest flash with the lights off thats it. Everything else runs Fine.

I'd Suggest running a 912 LED or SMD in your corner light though, it should fit and will give off alot better light. It has the same base its just a little bigger & brighter bulb

 

Post a vid, Ian.



My buddy trevor is completely HID and LED. he's got no halogens/incandescants on his truck anymore. I think he's running some 14 SMT's in his corners. He's un-blinker modded.

 

odd, I gotta lil thread jack here, in Tre's pic what kinda LEDs is he running for the 3157s looks crazy bright!!!

 

ummm...idk. he's a *****, so i think he's posted a thead regarding his complete LED swaps.


I wanna say they are like 60 5mm's off ebay. SUPER bright at night. Literally lights up the ground and is hard to look at in pitch black.

 

it sounds to me like blackonblackfx4 _is_ having the problem -- he states that the corners do not flash when the (parking) lights are off.

That is because they are reverse-biased at that time, and LEDs will not light up when they are reverse-biased. If you put a set of LEDs in parallel, but with reversed polarity, in those lamp positions, then they will flash whether the parking lights are on or off.

 

Yup.. I've got 194 leds from superbrightleds.com in the corners. When the headlights aren't on the leds blink in sync with the blinkers, when the headlights are on, they alternate with the blinkers. Is it not supposed to work like that?

 

mine does that, they all do that with the mod...

 

SHOW ME!!! vid please.


When I tried this with LED's, it was massive failure because of the polars of the LED's.

 

here ya go... you'll see the swap of sync

LED's cody, LED's. lol. Not incandescants. lol.



This thread is about the turnsignal mod using LED's.









*kicks and giggles...here's my vid i did like 4 years ago..with incandescents...

well it did the same when I had the lil amber LED 194s in there... took em out b/c they were really dim funny thing i noticed is when you have the incadesents in the center and you hit lock on keyless entry they take a second longer to flash than the LEDs :-)

 

Something wrong today! My hazzards dont work with the headlights on and truck running anymore! they work with lights off, or if the trucks off though, and the fuse is good.

Only thing I did was add the 3157's SMD's in the tails. other than that I have LED mirror lights, LED corners and front signals

 

Did you ever get an electronic flasher?

 

Yeah I put a napa EP 27 as well not sure if that effects it,

or when i pulled a trailer last weekend, it wasnt working that might have done something too?

 

You need to check your blinker fluid.

 

Is that Napa flasher made for LED's?

 

Im 99% sure it say'd LED on the flasher, It has no hyper flash or anything, Just the hazards quit with the truck running and lights on, If the truck off and lights are on they work. Or truck on and lights off they work.
