Switching from Regular Lights to LED's

The 2011 K9 250's came stock with the 1157 two element bulb setup, along with HD style controls & primary. My problem is not with the existing 3 wire set up it is with the 4 wires on the new led lights. I'm starting to think what I bought will not work with my existing wiring or at least not with my knowledge base!.
Wow news to me on those.

However the circuit logic still applies. You should easily be able to decifer what the function of the circuits are.

Update:
Drilled & tapped fender strut hole & installed heli-coil for new tail lights, no issues.
Problem: Existing tail light/blinker harness is 3 wires & not LED. K9 250's have the 1157 style bulb set up. The new Kellerman Bullet 1000 DF's have 4 wires. I have determined which are the ground & blinker wires, both new & existing. That leaves with a new grey w/ white stripe & a grey w/ red stripe wire. I connect the new grey w/ white stripe to the existing red wire & the red halo ring comes about half power which makes me believe it's the running light. When I connect the grey w/ red stripe wire to the red wire or the blinker wire the red halo ring gets very bright telling me that wire is probably for the brake light function. The problem is it goes bright red as soon as I connect it so when I apply the brakes it doesn't get any brighter.

Any & all ideas are appreciated.

So I will assume that you have the 3 in 1 light for the rear? If this is the case it is designed to have a turn, brake and tail light all separate signals. In our bikes the brake and turn are the same wire. Connect the tail light to the light wire, then I would tie the turn and brake together:

Rear
Strip the four connecting cables on lamp and vehicle for about 10mm each. Twist the positive vehicle turn signal wire to the yellow wire of m-Blaze edge, insert it into the supplied crimp terminal and crimp. Repeat this step for black m-blaze edge wire with vehicle earth, brown m-blaze edge wire with rear light and red m-blaze edge wire with brake light.

Not sure exactly what model you got but it should be the same as above.

Did you have the bulbs before you switched?
Yes

Or just buy 3 wire signals like I did.

For the front lights did you just cut the wires and solder them back with hear shrink or did you run them back to the plug under the gas tank?
Ran the wires right back to the plug, although I went with Adjure signals on the front, they are very small and the match the Adjure headlight bucket..

That is one reason the guys in europe often have two rear lights, or have changed the EHC to European model. I did google the problem when I took my Choppa to Europe ( red blinkers are no-no ) the only solution I found was to build a converter and that was beyon my skill level,
So I left them original US specs and told the inspector no can do and I will not accept 2 separate lights to spoil the bike. Being flexible guy he agreed with me.

Glad it worked out for you. I ordered some of the Chris turn signal lights so I will see how it goes this week when I try to install them.

I took my front lights apart and the right light has a brown wire and the left light has a purple wire. That is all there is and they are just grounded inside the housing and where they attach to the triple tree. I bought the Chris lights and each light has one brown, one purple and one black. They will not light up no matter how I connect them.

Can anyone give me some help or suggestions?
Thanks

Ok I bench tested them and they work fine. I must not of had a good ground. I thought the amber lights in the front were always on when the bike was running and then when you hit the turn signal switch they would blink. There were 1156 bulbs in the front so does that mean its only turn signals? no running lights?

If thats the case can I somehow hook up the brown wire from the light so when I turn the bike on they just turn on like the headlight does? and blink when I hit the turn signal switch?

Thanks

Front signals are just signals, not running lights. I ran my ground on the front signals very short with an eye connection and it goes to the base of the mounting bolt. As I said these are Adjure signals.

Rear are the run, turn, stop function LED's.

Yea thats the same way mine operate. It looks like you have a mounting bracket that bolts on to the front forks. I am trying to figure out the best way to mount mine. If I had a threaded stud I could still mount the front lights on the bottom of the triple tree just like the old ones. The problem is the old stud does not fit in the new housings. I think is is just the type of threads it has because it starts to screw in but stops after about a turn. I may have to tap either the housing side or in the triple tree I have the same problem in the rear.

Did you have this problem?

Kellerman being made in German most likely has m/m thread?

No, I bought standard thread signals, as Tapio says you've most likely got metric. There are lots of options for mounts, here's an example

Same issue I had with my rear tail lights from Kellerman. The bolt was the right diameter but the threads where off a bit. I opted to drill out the existing threads & tap new ones for a heli coil with the proper thread pitch.
