i dont know im not really into the hole led craze so i wouldnt know how much, but if u can pm a a price u think is worth your trouble ill pay it, ive wanted to turn mines white but idk how to soder
hey guys, really quick question, i just bought a pack of 50 of these leds to change the turning signals to white and it came with resistors, how can i install the resistor onto this???

you don't need resistors.
the voltage going to the mirrors are already ~3.3V
my only guess is a poor solder joint killed the led. i've seen it happen... the one's i've done just like the diy's have lasted for a long long time... no issues yet.
other designs i've done have been fine too.
but yea... i'm working on an array setup too... i just need to find time

shine brighter....?
you two are confusing me..... i'm thinking blah blah lining up all the leds in series.... which will cause the leds to not light up bright enough at all because there isn't enough voltage to push thru the entire series...... then there's wiring them all in parallel... at which then is what i think phiquach is trying to say..
here's something i made that works...

testing..

yeah yeah... the whole current thing i didn't calculate anything for... i knew the voltage coming to the mirrors was enough to light them up so i wired all of them in parallel... this would be the non-engineered way of doing it... and yeah.. the leds aren't as bright as they could be because of it... current is going everywhere....
but hey.. i was bored and had ALOT of amber leds from all the led swaps i've done..

that looks nice if it's in white!!! i had 4 blown up already... the driver's side is now not lighting up.... i haven't fixed taht... but if u can get them all light in series like that, i would like to do that instead of 2 3mm LEDs...
yea squallheart thats what i was trying to do, but i mean if there isnt enough voltage to go through all the leds to brighten them up a bit than i will try and find something maybe from autozone or something that lights up in a str8 line and white
You should always have a resistor in line with an led unless you are running below its threshold voltage all the time. An led, when reaching its threshold voltage, turns into a practial short. They are not like a linear resistance. So if you have one led with 3.3V applied, you are right on the edge of creating a short and killing the led.
If you have multiple in series here, it is not as much of an issue since you are adding to the threshold voltage you need. But then you end up too dim.
I havent messed with the turn signals yet. What type of power is coming into the housing? Dont measure across the leds, measure right where it comes into the housing. On a 3.3V led, you will always read 3.3v across it, even with 5v applied. The led will only drop so much and the rest is dropped across the rest of the circuit (or the leads of the led, in which case you are soon to burn it out).
So basically, what voltage is actually being applied from the car to the mirror turn signal circuit?

for me.. it's about 3. something.. 3.2.. 3.5....
but looking at the stock leds themselves and the diagram that goes with it there's two of the amber snapleds (that are tackwelded on there
and then there's a mysterious resistor after that somewhere that's not inside the mirror housing... which i have no idea where it is.. but it's on the cathode side.
so in a sence you have a general idea or range where the voltage is..
the mirrors are resistored at least already for those 2 leds in series... and then via the DIY here.. the voltage running them in parallel with white leds seems fine as i've done the same exact mod in another car and the leds have lasted so far.
hmm... though i have seen some individuals not having the same luck...
and then my array that just takes that voltage and splits the current to yea... sorry if i disappointed you... i did say i was bored..
hey.. it works...
