Installing LED flush signals help K4 600
I'm installing LED front flush signals on my k4 600 gixxer. I can't get them to flash when connected to the stock harness.
1. When I connect the LED signals to the harness they don't flash (or work at all)
2. When I connect the LED signals straight to the 12v battery they light up fine
3. When I connect stock bulb signals to the harness the bulb flashes fine.
The weird thing is I also have a set of LED signals on the rear and they work fine. I tried checking the fuse under the seat and it's also fine.
What am I missing here? Thanks for any help.
how many wires come from your stock signals? 3? and only 2 from your new ones? ive had this problem before too, on my 89 gixxer the front(only) signals were supposed to stay on when NOT in use then blink when in use, they had three wires. seems to me you will either have to buy two more for the front(with the proper wiring) or you will have to do some custom wiring to get them to work with what you got there.but they may have to all stay off untill you use them. keep in mind they may use something different now than the third wire like on the 1989 bike. i have also seen on youtube these led's using some kinda relay perhaps it needs a different relay than the one the bike has? i wish i knew more....i am still waiting for my signals to show up in the mail if i get this shit figured out soon i will reply again.
You probably need a special relay for the LEDs, something to do with them not drawing enough power I think. Go to eBay and search for GSXR LED relay and you should find what you need.
i have the same bike and it worked fine for me when i installed it
i can help u out if u want. msg me
Thanks for the replies guys.
There are 2 wires per signal only, so I don't have to worry about the running lights. I looked into this a bit further, apparently a kind of relay is needed or wiring resistors in does the job. Weird thing is I have LEDs on the rear and they flash fine. Anyways I'll stop by radioshack tomorrow, I read that an 8ohm 50 watt resistor per signal might do the trick. Kinda a pain, i thought itwould be a simple plug in mod...
Mr. Squid, did you have to install resistors/load balancer to make yours work? Do you have LEDs on the entire circuit (f+b) or one pair only?
i dont have load resistors ..fronts and back flash very fast cuz of that.
Maybe it could be the brand? if u want i can meet u up and take mine out and plug to ur bike. im using hotbodies and ebay rears
*edit or try swapping the fronts to the rear, vise versa and see if there is problem with wiring in the front.

The easy way is to get the special flasher but you can use two power (wire wound) resistors , 5 or 6 ohms @20watts is about right the minimum you want to go is 10 watts because turn signals are intermittent use and they wont get that hot. you dont need a 50 watt one that is way to big (3/4"x5") 13v @ 8 ohms =1.6 amps=20 watts WTF? If you go this route try places like Active Elc. or MRO or Quale all on Boundary @ 1st
Good news, got it working guys. Great advice there Mech!
For future reference to anyone doing this mod:
I used 2x 10watt 5.1 ohm resistors, $1.99 at Active Electronics on Boundary and 1st like Mech said (10 watt is the highest rating I found in stock, otherwise it's an order-in item. Should be good though considering each LED has an imprint of "1 watt" only?) I have 4 LED's all around, but I soldered in the resistors on the ground wire of each turn signal in the front only. Before they wouldn't flash at all, now they flash and at a stock-like rate and all is good!
glad to hear that one more thing , keep the resistor away from wires or plastic. If there used for more than a minute or so it will get warm.
