So as some of you may remember, I picked up a clear alternatives 2003 integrated tail light, and modded it to fit in the tail of my 07. Well now its time to wire it up. The tail light came with resistors, and I have no clue what they do. I double checked all the lighting on a 9v and it worked just fine, as well as tested it on the 12v circuit and it was plenty bright. All OK, and testing was done without use of resistors.
I wanted to know if the resistors should be wired in, what they actually do, and will anything bad happen if I do not put them in. The light is built into the tail of the bike, and is permanently attached. I want this to last, cause if I blow the lights out, I am going to have to scrap the tail and start over, or have one hell of a time replacing the electronics.
Thanks for the help.

You dont need the reisitors. Their purpose is to slow down the amount of power going to your lights if they are blinking to fast. If your lights are blinking at a normal rate then your fine. Im actually about to put resistors on mine because one I turn my signals on they are on solid without even blinking

If you have resistors in the front turn signals, then you wouldn't need them in the back. However, i'm gonna assume from your post that you don't have them  . Basically, without resistors, here's what will happen.
-If you have one set of stock signals (in the front for example), and wire your integrated taillight without resistors, you will get a faster-than-normal flash rate. Most people actually like this faster flash.
-If you have aftermarket LED signals in the front AND you wire your taillight up, when you turn on a signal, it will blink so fast that it literally looks like it is just steady. Not good as a turn signal. If you install one set of resistors (in the front OR rear, doesn't matter), it will slow the blinking rate down to that faster-than-normal flash. If you install resistors in the front AND rear signals, you'll get a flash rate pretty close to stock.
On a side note, the resistors get wired in like so:
----ground-----------------
l
resistor
l
----positive--------------------------------signal wire
The resistor is there to basically eat up some of that excess voltage that the LED's don't need, therefore it gets wired in-between the positive and negative wires to complete the circuit BEFORE it reaches the turn signal.
Hope this helps!! Let me know if you need anything else. My advice is that if you are replacing all of your signals with aftermarket ones, wire in one set of resistors, and you'll get a faster-than-stock flash rate that is very visible to traffic!

Perfect.. thanks guys. I have led front signals, and will be wiring in an led integrated tail light.... although I did have the bikelitez one on there with no resistors and the flash rate was pretty close to normal... guess I will just have to play with it. Thanks again!

Yeah you dont need them. But you may run into a problem when your bike snt started and you try to turn on your blinker and it stays solid for a minute. Or when you first go to turn on your bike. But after that it will work fine. My bike does that because I did front and rear with no resistors and they look solid since no power is being used anywhere else.

If it works let me know, I was thinking of doing the same thing...It just seems to be the most cost effective alternative

all aftermarked signals on my 07.. front, and FE... mine blink fast, no problems with them staying on or anything..
i feel alittle more visible with it blinking faster.
oh yeah.. no resistors at all.

How could the resistor possibly get wired in after the turn signal? I don't even think it's possible to ponder that. Maybe if you haven't taken it out of the box yet?
In other news does anyone here currently have resistors and if so how hot do they get? Will they melt the tray at all? I just got my integrated tailight and i did some tests with it. Everything is working fine i just dont know where to put the resistors(they are massive).

umm guys the resistor actually causes current flow to increase (resistance in parallel is recipricating) the smaller current requirement of the leds makes the flasher module blink faster.... dont belive me hook a headlamp bulb up in place of the blinker and the flash rate will decraese inversly with current flow.

So I wired it all up, no resistors, and I have a consistent flash rate with the bike both on and off, and I have LEDS replaced for all the lights on the bike (except headlights)
Im thinking that might change however when I install my HIDs and the DRL cutoff.

Ohm's law;
E=IR meaning Voltage = Current times resistance...sooo....more resistance, with same voltage,leaves us with less current. less current means slower blinkies! LED voltage is 0.7 volts, thats a constant, or needed to work..its just a ratio that has to be met thats all..

Resistors are polarity free, btw..if you have a series circut..then the current will be the same through all devices, resistors will drop voltage..all the devices in the circut will have the same current flow through them, and depending on the resistance of each device, will determine what voltage drop it will have..but all the voltages in the circut HAVE to equal the total voltage..so, say you have a 12 volt battery ( conveniently enough) and you connect a resistor in series ( so, a resistor with 1 of the leads on the positive and 1 on the negative, you will have a 12 volt drop across that resistor. if the resistor is say 220 ohms, then the current will be..( using Ohms law..of E=IR...) 12=Ix220 ....I = 12/220 54.5mA I = 54.5mA so the current flow of this particular circut is 54.5 mA
seris cct, is like a train...chooo chooo!! everything is connected after eachother..1 lead to the next.
parallel is where there's a split between 2 leads..or more than 1 path the current can flow..
A relay is just a switch that switches a switch..like the ignition in your car..current draw of a starter is more than an amp, and 500 mA will cause heart palpitations, so I think starters are what, 15-20 amps...so that ignition ( where you put your key in everyday...) is a relay.
