I am working on ATV lights. Originally, it had 2 25W headlights. I have replaced them w/2 LED lights (1 flood and 1 spot).

There is a low/high beam switch and I wired both wires to the flood. I wired just the high beam wire to the spot light...hoping to get the flood light on both settings and also get the spot light when on high beam only. 1 on low, 2 on high.

The problem is that on low beam I have 2 lights. I assume because the low beam voltage is feeding back through the high beam wire in reverse direction.

What do I need to stop that and where would I buy it at?

How much current does the low beam light draw?

Since they are LED, they don't draw much current. You can separate the wires with a 5 amp diode. Connect the Hi beam wire to the spot and connect the low beam to the flood. Put the diode between the wires with the stripe on the diode towards the flood. On hi, current will flow to both lamps, on low, the diode will block current to the spot. Radio Shack or Fry's Electronics will have them.

The low is 12W, (4) 3w bulbs/LEDs...1 amp?

I will start looking for a diode.

You'll be good doing what Don posted. With the answer you posted I was going to give the same directions. Try to find a local electronics store, use Digikey or get them real cheap shipped from Asia on Ebay. Look for one with a high voltage rating too so it withstands any transients which may occur. Should be easy to find a 400V+ rated diode.
