Hello Lads,
My wife just ordered me the acrebis twin halogen light set up. Now how can I hook this up so when I hit the high beam, both lights will be on?

I'm planning on running the low beam to the flood lamp.

Please be as clear as possible cause I'm a noob at electronics. Many thanks in advance.

I haven't done this but I can explain the procedure, some else might be able to say exactly where to change things. There are a lot of ways to do this. Probably the most straightforward would be to let the feed from the dimmer switch run the low beam as in stock, then take the feed from the dimmer switch that would normally run only the high beam and feed both lights with that. I would suggest a relay on that combined high/low feed. The relay is used so the fairly high current of the light circuit does not need to go thru the dimmer switch - which is wimpy and has small wires and causes a voltage drop which makes the light not as bright as it could be. Your dimmer switch normally turns off the low beam when the high beam is turned on. There should be 3 wires going to that switch, one will be the positive basically from the battery, one will go to the high (might be yellow), one will go to the low (might be white). I say might on the colors b/c that is what is in the manual which is questionable, I think it also has a mistake in the drawing where it shows the dimmer positive feed line coming from. Anyway, test the outputs of the dimmer with a voltage meter, The high and low will toggle, on and off, with the switch, the positive feed should always be 12 volts or more when the ignition is on. Those high and low beam feeds lead to a fuse box, that might be an easy place to test or start rewiring. Your goal will be to find a place where you can take the feed line from the dimmer going to the high beam and use that to turn on a relay that will then feed both lights. The relay itself will need a positive feed from the battery with wire a couple sizes bigger than what is used for the dimmer circuit. If you can't keep the stock fuses in the circuit you will need to put one in, speaking of fuses if both lights run off the same fuse that originally only ran the high, that might need to be swapped to a bigger fuse.
Anyone - feel free to correct or slam this, If I was doing it that is how I would go about it, that doesn't mean there aren't better or easier ways
Rocket - how many watts are those bulbs?

Bingo. I have the Acerbis blitz on my DR350 Off-Road (dualsported) and run the bottom beam as the low beam and both beams as high. -Steve

does the factory light run the low beam at the same time as the high beam? For some odd reason, i don't think they are run at the same time.

The factory doesn't run both at the same time, I just want to turn up the lighting dept. a little bit.

i agree, i think the stock lighting on the 650/400/350 is inadequate at best. My brother just put some new lights in his gsxr1000 the other day(or should i say, I did them for him) and they are a very nice upgrade from stock. They're from sylvania and i think they have are called silver star or something with silver in the name.

That almost makes sense to me, but I'm new at wiring and barely understand relays. the lights are 35w each I believe. The install sounds complicated as all get out, I think I should have had her order me a skid plate instead.

Where would the wires on the relay go? I realize one to the battery, one to the light, and I would guess one for ground and one for the switch, but which one goes where? i.e. contact 85 goes to groound, 86 to battery, etc.

Very helpful and I'm a dunce so your doing very well.

Sorry I probably made it sound more complicated than it is. I can't be more specific w/o looking at it. My bike is STILL :foul: in the shop or I would take off the cover and be able to tell you which wires. I thought about it last night and setting it up like you want would probably require a second switch. If you wired the new light the same as stock, then added a switch which would turn on the high beam separately that would work. Simply put all you need to add is a wire from the positive on the battery to the switch, then run a wire from the other connection on the switch to the wire that feeds the high beam (between the stock switch and the fuse). You would end up with a stock switch which would be either high or low beam, and the ability to turn on the high beam with the new switch while the low beam is run off the stock switch. If the new switch was turned to high you would get the high beam reagardless of if the new switch is on or off. If you wanted to put a relay in this additional feed to the high beam you it wouldn't hurt. A relay is nothing more than than a switch that is turned on and off by putting 12 volts to it. It has 2 sides, an output side with 2 connections and a control side with 2 connections. Typically the output would have one connection wired to the positive on the battery, the other output connection would go to the light. (on the output side, it doesn't matter which connection goes where, it is which just like a light switch). The control side has a positive and a ground connection. The positive would be fed from from your new switch, the negative would go to ground. One connection on the new switch would be connected to the positive on the battery, the other would go to the positive on the control side of the relay. When you turn the new switch on it sends 12 volts to the control side of the relay, this turns the relay "on" which basically makes a connection between the 2 connections on the output side so current can finally flow to your high bulb. Rereading this I have probably driven you to exchange the Halo for a skidplate :excuseme:

:crazy:

What bike are you installing this setup on? Like I mentioned above, I installed a dual beam setup on my 1999 DR350 Off-Road. I ran the headlight wire (from the stock headlight) to the bottom beam. I then spliced a second wire into the headlight wire (running the bottom beam) and ran it to a switch. Then I ran a wire from the switch to the top beam. No resistors or anything else (of course you need to run the ground wires to a ground). Extremely simple install.

You can see pics of my DR350's HERE , including pics of my '99 with the Acerbis Blitz.-Steve
