bought a pair of high level brake lights for foxeye"...with the intention of wiring up to the exsisting brake light?...now ive got a black and red wire from each light and at the rear of the bikes light ive got a yellow,blue,and black?...according to mr haynes the blues the live ,the yellow is from the brake light switch,and the black is earth!!....so ive wired up black to black and blue to red and nothing!!....even tried taking the red to yellow and still nothing!!...what the fk am i doing wrong?...
Are the existing tail and brake lights still working?
Silly thing , but have you checked fuses.

What are they ?
I don't do rain or threat there of. dry rider only with no shame.
Check the connections are good and take out the two bulbs and then see if it led light works.
Yellow to Red and Black to black looks correct.
Made in england......think you've answered you own question :rolleyes
One, is never going to be enough.....
think u may be right paul?...usualy everythings china isnt it?...anyway update still dont work so bk to the drawing board?...chkd them again off and the work perfect!!...where art though fazerider??
Have you tried wiring them back in as before black/black & blue/red but remove the existing brake lamps/bulbs.....then try it!
Those are my principles...if you don't like them I have others.
How have you spliced onto the existing wiring? If it's by one of those insulation displacement clamps, was it the correct size for your cable? If it's too large it might not have cut through the insulation enough to actually make contact with the conductors.
You shouldn't need to worry about relays, the current taken by LEDs is very small, the existing wiring will cope OK.
If they are working directly to the battery and the brake light are working then it is your connections which must be at fault.
As Fazerrider says if it is those insulation displacement they may be the wrong size.
I would never use these type of connectors as they are nothing but trouble.
Disconnect the plug to the lights and connect the led lights into them Yellow to red and black to black. Do they now work, if so then it is your connections which are wrong.
with a bit of care you can remove the insulation with a cutters and connect the led light wires directly wire to wire.
Solder the connections and tape it up.
The reason I asked to remove the bulbs and try it was because of a problem brought to me a few months ago and they would glow lightly with the bulbs out but nothing with the bulbs. After much head scratching, I saw a very small sign on the lens "24volt" the led lights he had bought were for 24volt running. :lol
Have you got access to a multieter?
If so, check the voltage between the two wires you are trying to use on the bike is 12V (with the brake light on).
If so, connect it up and check again, (with the brake light on)
If it's still not working, check the voltage between the two wires as close to the LED light as possible - again it should be 12V.
If it's 12V there, you've got a faulty unit
If at any point you stop getting 12V, sample around a bit until you can confirm exactly where the voltage drops off - it'll probably be somewhere in the new wiring. Bingo! You've found your problem. Depending on where it is, you may be able to bypass the problem section with a new piece of wire.

I still dont know what they are?

How high is high level? :eek
Better to have it and not need it, than to need it and not have it..
....1/ the scotch locks where the wrong size!..and 2/.decided to follow unfazed idea about soldering them?...going to do that today!!..when its sorted i will put up a piccy helps incase of a rear ender mabe :rolleyes ....went for the flat truck type instead of the thin led strip type, these measure about 4inches by just under 2inches look quite good from rear!! cheers for your help men!!
