it doesn't make either light brigher, but rather makes the high beam on (but less bright) while the low is on, and when you hit your high beam switch, your high beam goes to full intensity
Dual Headlights With Write Up
10
I am no longer making these. I sold my bike.
Hopefully the mods dont get mad, as I messed up the last write up and want to start fresh.
Things needed.
1-10amp SPDT Relay.It is also made by NTE. Can use one found at an automotive store. $5.99
1-1ohm 25 watt resistor, or 2-2 ohm resistors wired parallel.$1.49 http://www.nteinc.com/resistor_web/resistors.html
(THIS IS FOR 55-60 WATT BULBS. DO NOT USE 100WATT BULBS FOR THIS)
I used an enclosure to put the relay I used in it. $4.99
Should be able to find these at an Industrial Electronic Store.
5' of wire
Soldering Iron, and some Solder
1.5 hours of your time
www.active123.com is where I got my stuff. They are located in Canada tho
Add all the wire to the relay. Leaving at least 12" of length for the wires going to the headlights, and about 8" for the ones going to the resistor.

The relay should look like this

I used mostly all black wire so It looks closer to stock looking.
Then drill out holes in the enclosure. 3 on one side, 2 on the other.
Slide the wires through the holes until the relay is in the enclosure.

Should look like this

Flip over the enclosure. I put about 5 layers of electrical tape to protect it from the heat of the resistors.
Add the wire to the resistors. Make sure to solder the connections.

I then cut the wire, and added some heat shrink. Then taped the resistor to the enclosure.

The relay is done.
I placed the enclosure under the instrument cluster using some double sided tape. It is hidden and out of the way.

You can follow the first picture on how to wire it to the bike. Solder and heat shrink all of your connections
Stock With One light Low beam
![]()
With low Beam on 100% and High Beam on at 40%
![]()
With Both Lights on 100%
![]()
This can be done many different ways. This is just how I did it this time.
If I do another I might try to incorporate everything inside an enclosure.

I am using 2-2 ohm resistors in parallel.
If the relay is clicking very quickly, you more than likely have a short somewhere.
If you wire it this way with the resistors you have. The high beam should be around 34 Watts of out put when using 55 Watt bulbs when on low beams. Theses values are all approximate. Your resistors should run fairly cool then too. By using 1 ohm resistance the bulb is around 28 Watts of out put.
If you can get another 1 ohm resistor. You can add it in series with the single one. Then you would have 1 ohm total with the others run in parallel with it.
