    Default electrical question

    Hey guys, so I'm doing some stuff to my bike, and I really want to use the other two headlight plugs on my front end. But because I have the dual sport headlight I only have one light that is being used. CBR have the two plugs for low and one for high. Is there a way to reverse that? So that the one is on all the time and when I hit the high it turns on the two others? I'm not sure if how I'm explaining this makes sense.

    It would help if you could post a pict. of the back of your headlamp. Does it have three lamps? It sound like you are using one and want to use two additional. A pict. of your headlight connectors would help too.

    I presume your harness has a connector for low a connector for high. That low is always on (US style) and high is only on when you throw the high beam switch.

    Had to google, because i'm not entirely familiar with the 929. (good explanatory image: http://images.motorcycle-usa.com/Pho...02CBR929-2.jpg)

    it sounds like what you have going is the one of the low beam plugs is powering a single light, low beam only. i don't see any reason you couldn't continue that, and wire the high beam plug to a relay to kick on whatever lights you want to wire up (and the electrical system will support).

    high beam plug > relay > whatever lights > ground (i can visualize this better than i can explain it, apparently? ( had a drawing somewhere of the basic concept that i sketched related to something else... )

    added the diagram; this was based on running a h4 low, and a separate h3 hi, powered off of relays and triggered via the stock switch. basically what you're looking for is the "hi" side of things with your existing high wiring to a relay, 12v from battery to the relay, and the relay feeding whatever lights you want to turn on as "high beams".

    If this helps! They are all h4 plugs and I currently have my headlight in the hi spot. I want to use the lows for something like the Trail Tech hid spots, is there a way to switch the polarity(??) On the switch itself so the hi spot is always on amd the lows only come on when the switch is pressed?

    Easy..
    The rocker switch high or low use that plug, the remaining plug use that as the other low or high. You will have to tap in or change connector for specific applications. Diagrams don't do no good if people do not know how to read the schematic. If your new application has higher amperage don't be surprised in the future finding burnt wires. If your plugs have 3 terminals then you have dual filiment bulbs for high and low. If your still confused and need services you know who to contact.
    what do I do..build/repair/engine swap/sell aftermarket and factory parts/used parts/make custom decals/screen printing/ banners/business cards/promo pinback,magnets,mirrors buttons for all occasions/embroidery coming soon Insurance work welcome...

    still having trouble visualizing exactly how the three bulbs are wired to behave. it sounds like when you switch to high, only the middle is lit, but on low, the outside two come on, yes?

    It sounds like you could just wire the headlight you have to one of the existing low beam plugs (so its on when you're on the low side of the switch, and then wire the spots you want to add to the high beam plug.

    As SF Boyz mentioned, if what you want to install is going to draw more current than stock, you probably want to (realy should) run the new lights through a relay. Second, what i've read (and seen) of HIDs, they take a minute or so to come up to brightness once you hit them, so maybe not the best to run for "on demand" lights. (Side note: most of the h4 HID i've seen either use a reflector or shift the bulb for "high beam" operation, so it's already up to temp).

    I also wouldn't hesitate to use his services if I needed electrical work done.

    I was referring to the drawer of the sketches, Jen. I don't think I know too many guys named Jen
