Do led front turn signals need resistors???

[PHILLYTONE]

Im replacing my stock front turn signal bulbs(3157) with some new 25 led wedge bulbs i just got. Can anyone tell me if i need resistors for the bulbs or will they work as is??? Once again not the drl's, just the turn signals. Also if they do need resistors, where can i buy them? What kind do i need? And what is the installation process? Any instructions? Thanks in advance for any help, links or pics!!

you shouldnt need resistors. The LED you mentioned comes with a built in resistor. the only thing is if you plug it in and it doesnt work, try to flip the connection. Negative/positive make a big difference in the LED world

I got the leds from superbrightleds.com ... They are the 25 led 3157 wedge type....if i plug them in the wrong way, will one one be dimmer or brighter than the other way or will one way just not work at all?? That question sounds weird but i think you know what i mean...

yeh sometimes they are dimmer and sometimes they dont turn at all. i think. flipping them will fix the issue tho. i purchased all my LEDs from superbrightleds.com

I purchased LED's from VLEDS and resistors were indeed needed.

Hope that helps,

You connect them from the +\- of the bulb. They get wired between them.
