    I want to add a driving lamp...

    ...to my '03 R1100S.

    There are many available, each with their own wiring harness, relay and switch. I kinda like the one from Wunderlich....
    http://www.wunderlichamerica.com/mot...S/8600530.html

    Here's my question: I want to operate this lamp with my high beam switch. Can I simply splice into the existing high beam wires or I am courting a visit from the friendly local fire department? The unit itself draws 55W.

    What say you, o' gurus of all things electrical?

    You're going to blind oncoming vehicles.
    You're better off having a discrete switch.
    If life throws you a curve; lean into it.

    It is unlikely to be a good idea to just tap power off the high beam. The draw would likely be too high. Better to use a relay and use the high beam tap as switched power for the relay.

    You can do it like this:



    The relay hooks up like this:



    Adding a switch allows you to turn it off even with the high beams on. You can add power and use a double throw switch so you can turn the lights on without the high beam too.

    LED might be cheaper and brighter?

    From the description: ”The kit includes the bracket, lamp, bulb, relays, switch +wiring and all that is needed to fit it.”
    I guess you could tie the relay trigger to your existing high beam (or low beam, if it is a driving light) wiring, instead of using the switch that comes with the light. That would put a very minimal additional load on the existing switch. Better yet, you could run both the existing and the additional lighting through the relay, and get a bit higher voltage and therefore better light output from your existing light (unless the S already uses relays for the headlight?).

    Or you could do all that, but with a higher output LED instead of this 55W halogen light.

    Alrighty then...I'll bring the parts and meet you at the Billings rally. You seem to know what you're doing, whereas I....

    I won't be there, but IF I were it would be no problem.

    get a set of fork mount driving lights that can stay on all the time. LEDs are a good choice. better for conspicuity.
    get a set of HIDs as replacements for your stock lighting. I've been running like that for over 12 years- yet to replace anything on the HIDs. the halogens I've been running as driving lights last about 40K miles, give or take.

    Not quite the same as what I've been running, but I bet these would work nicely.

    Best relay pic/annotations I've seen, Jim! Nice work.

    Use your high beam wiring as the trigger signal for a relay. A separate switch is just a distraction and just something else to fail (you're going to have to use a relay anyway).

    A little late to the party...usual excuses, finishing the new house, moving in, cleaning up the rental house, yada, yada, yada.

    Set up I got for my S is similar to what I used on my 1150R. Hella FF50's, Autoswitch (utilizes the turn signal cancel button as the auxiliary light switch. On the R, I just screwed the mounts to the bottom of the oil cooler shrouds. For the S I got a set of brackets (brand name when I can remember!) that mount to the valve cover bolts. Stuff is still in boxes, and "available". I don't ride at night anymore...

    I used the fog beam pattern On my 1150R and found I could leave them on all the time without distracting other drivers, these FF 50's are sort of old school halogens but put a lot of light out on the road.

    Now, back to unpacking two million boxes...lol.

    Cheers! Bill

    Yes, but I like to be able to fully control my lights. As for the switch being "something else to fail", seriously? It can't get more simple than a switch!

    And an add on comment, after re-reading all the posts, including that OP guy from north of the border.

    That microflooter from Wunderlich is pretty cool, especially if you're not looking specifically for a conspicuity feature. I like the triangle of light with low mounted auxilary lights, and the Hella fog lamps really light up the deer traps along the roadsides. But a pure ultra bright driving light is a whole 'nother story.

    The switch I mentioned previously is (I think) still available from Aerostich. Or...I have one available for the price of one beer (maybe two?), someday...say in Billings?. Or Port Angeles?

    Cheers! B

    PS. A bit OT, but my memory banks refreshed automatically, and the brackets I mentioned earlier that mount to the valve cover bolts are called Talon mounts by Hawksproducts, and advertised in the ON. Amazing how the brain pops up these tidbits when you quit "trying" to remember.
