LED bulbs. Flasher or Resistor?

That's weird the front doesn't, but yeah, you guys were right. They blink fast. Can you buy any resistor for 12v applications or does it need to be a certain one? Last resistor I bought was a white box with 2 wires sticking out of it, like not copper wires but just one little silver wire like a paper clip, and i had to somehow try to join that into an actual electrical wire?
Really wish an electronic flasher would work. Or find a decent resistor.

The white was probably a ceramic one. They are not as high power rated as the bronze coloured barrel type. You want 60 or 70W ones, 2-3 ohms.
Far right is what you want:

Is thisone here more like it? or just like the white ones but painted? haha
Also, do i wire one into the top and bottom bulbs of each tail light or is there some point where i can just wire one on each side

Best place I found was to remove the taillight itself, and attach there. The R's get real hot- there are 60-70 watts of power passing through those each time you hit the brakes, use the signals. I actually used a self tap screw to mount the R's to the sheet metal back there to act as a heat sink to cool the R's. They WILL burn your finger tips. Its pretty weird.

That's it. 1 per side is enough. Does not matter if its the top or bottom bulb.

You mentioned the purple/black wire. I'm assuming that you splice both ends of the resistor into that wire? Also, where did you attach the resistors too with sheet metal screws?

What should we use? a 6 ohm 50w one? or what? So confusing haha. I might just mount it inbetween the tail light in there somewhere. v-leds.com sells some with brackets around the resistor so nothing really touches it, I kind of like that idea... it might be worth the extra $15

I am TOTALLY with you. I want LED's in the front because I have the front facing blinker on the mirror and want them to match, but I don't plan to upgrade if I have to splice wires in order to make it work. They should come pre-built in to the bulb.

I wonder if these work. Or do I need the '4 bulb' ones since theres 4 bulbs on the backs and not just 2?

agian, i really dont want to cut the wires and start splicing in crap. if my truck ever starts on fire and they find these im sure they'd blame them and id have no coverage.

Lessee..
Can't build R's into the LEDs as the power required ( P = V(squared) / R ), is;
P = 144/2.3 = 62.6 W. A 60W resistor is a lot of heat and very large.
You only need 1 R per side.
The R needs to go across the + and - of the turn signal wire. Does not matter what side of the R goes to what side. One side goes to purple, one side to black.
I screwed mine into the metal behind the tail light.
I will take a picture in the morning....
