LED Lights

Does anybody know why my LED lights flash when I honk the horn?

Doc here,

Check to be sure your not picking up power from the horn side of the horn relay..

Doc here,

And...Do they work normal otherwise? or only when the horn is blown?

They are in the dash, directional signal and high beam indicator.

They work normal otherwise, just light up when the horn button is pushed.

its not in the steering column because I eliminated that and it still does it.

I would apply a Diode to keep it from back feeding to the lights.

Doc here,

Good call Denny! I was going to suggest the same thing!

Try putting a 1N4001 Diode ($1.50 at rat shak for two) on the horn relay activate line..should be the small black wire.

The Collapsing field on the relay could be inducing a forward Bias on the diodes as the relay opens and closes, causing them to "Blink", It only takes a small amount of voltage to light them off.

Also be sure none of your wires cross that or other close circuits under the dash, give it as much separation as possible.

Doc
