    (stock is 55/60)
    Philips says this thing is 80% brighter.
    I won't show my work unless you just insist, but I figured out that with the stock 18 gauge wiring, the additional current draw causes a voltage drop at the bulb, which (because of the way bulb filaments work) causes a 2% drop in brightness.
    So, what you really get is a 65% brighter headlight (still not bad) and your wiring makes heat at 2W.
    That's not a showstopper by any means, but with the added cost and fragility of the bulb you might consider a 30% or 50% brighter bulb that still runs 55/60 W - first.
    Wish I could find the chart, but there is a considerable drop in light output on the halogen bulbs with a drop in voltage.

    I would upgrade the wires and add relays to my R 1100 S, But I'm still looking for a place to mount the relays.

    I use the silverstars and am happy. Guess I'll see how long they last

    you have space above the relay/fuse boxes on either side of the fairing inner. that is where I located my HID ballasts. can also fit relays on side of gas tank under fairing on L side (my HID relays got zip tied there)

    you can just see the ballasts (blue tops) under the fairing edge.



    but seriously, get HIDs. nothing else even comes close.

    Bikerfish is giving you good advice.

    The Silverstars are rated at about 1/3 the life a std bulb but do not put out more light than a good std bulb- just a different color temp and a little different focus. Carry spares- you'll need them. (H-1 bulbs can be hard to find on the road- it was already seriously obsolete when your bike was built in 2000 and being used by almost nobody even then- some of the usual parts places won't have one when you go looking, especially in rural areas where a lot of folks drive American stuff- I don't believe any American maker ever made a vehicle with an H-1 and off the top of my head I can't think of an Asian car maker who ever did either. It is strictly a euro or driving light application and most euro makers had moved on to the H-7 or other by 2000).

    It takes a little work to do an HID conversion but as pointed out, the projector optics of the bike are thye best possible base for a conversion and you've got the space for the ballast, etc.

    I'm not so much a fan of HID conversions for the high beam- they don't take to frequent dimming very well so you need to be in a really rural area to get much or best use from them. The 65W H-7 Osram is no match for an HID (2100 vs 3200 lumens) but is a no fuss, no muss upgrade from stock (1400-1500 lumens)

    I made a cute Excel spreadsheet I still tinker with. But it boils down to %(drop in brightness) = %(drop in voltage)^3.

    My earlier post saying 2% drop was in error - I ran the calculation at 12V. The bulbs are all designed for 14V or so.
    This improves it, since the voltage drop is less than the 2V difference.

    If you're going to get into grafting relays and wires on - Another tack you might consider - bike beauty notwithstanding - is keeping the standard (or only 1/3 better, like the Silverstar) bulbs in the headlight shell and adding on a set of flood lights or a set of driving lights. These typically run around 30W each and can run on 18 gauge wiring.

    I happen to think that the Silverstar is about 1/3 brighter than the "normal" or standard Sylvania bulb, but note that Sylvania says it lasts about 1/3 as long.
    And costs what, double I guess. In practice I find that the standard bulb lasts "forever" and the Silverstar lasts 1 or 2 years.
    The reason, and forgive me for getting arm-wavey again, is that the Silverstar is actually "designed" for 1/3 lower voltage - the filament is thinner, gets hotter, and puts out more light at a different color (spectrum) than it would at say, 9V or 10V. - They do try to compensate by using more spendy filament material or whatever but it boils down to heating a very thin wire to incandescence, which is, yknow dang hot. The cooler it runs the longer it will last. The hotter it runs the brighter it will appear.

    HIDs - the "ballast" gizmo runs the voltage up to the point where no filament is needed - the hot element is a plasma that can't burn through. Also once the plasma forms, this method of producing light is more efficient, so it might produce 3 times the light of the incandescent with 1/2 the power consumed. HIDs usually consume 30W or so. Again 18 gauge wire, so no need for 12 gauge and relays unless you just feel better that way. (On my RT the headlight circuit is not fused!)

    There are Sylvania Silverstars--which are PepBoys junk--and Osram Silverstars and they're not the same thing. The latter aren't blue for one thing and their life is normal.

    They're a good choice, as are Phillips products. PIAA anything are not, as they are all hype.

    HID are illegal and unsuitable with optics designed for halogen bulbs, projector or not. They are totally unsuitable as replacements for high beams, as they don't come to brightness soon enough to be used as flashers. Light units actually designed for HID still use halogen bulbs for flashers.

    The (fairly) new "+" halogens are new technology compared to original halogens and are the best you can do with that technology and optics designed for it. Like anything for credible German vehicles, they're not sold at PepBoys and just as you've expanded your horizons owning a BMW, you need to expand your parts sourcing as well. The thing to know is that in things automotive the USA is a 3rd world country and PepBoys, NAPA, etc., are dime stores selling ticky tacky.

    3rd world country? Oh that's gonna leave a mark!

    Seriously though, he's right. Most after market bulbs are cheaply made and do not last. Key word there is cheap for sure.

    mmmm... sounds like unfair characterizations of several organizations...

    Sylvania's actual name is OSRAM/Sylvania, a wholly owned subsidary of OSRAM - a german company.
    Nevertheless the OSRAM branded "Silverstar" has the same specs as the Sylvania "Silverstar Ultra".
    50% brighter (careful - compared to a worn standard bulb) - etc.
    I can't find documentation thus far to confirm or deny they are actually different.
    I too have always heard Philips and OSRAM were high quality.

    In the Sylvania brand there are 7 variations on "headlight bulb" and three of them wear a Silverstar moniker.
    Oh yeah a couple of them have blue tinted glass - don't know if it is for style or to filter some UV out?

    This is bewildering to me - you'd think that OSRAM would give their high-end headlight bulb a different name, even if the two products were identical, to further distinquish it from the brand label they sell in Wahmarx. I'm assuming that its because the Silverstar name is "catchy".

    Oh well.

    Is it just me or is this turning into a reasonable facsimile of an oil thread?

    I stand by Post #3. I guess I'm just lucky.

    Yup, very similar to an oil thread!

    But...if you were truly lucky, you would be riding a School Bus Yellow/Pencil Lead Gray S bike instead of that Pathetic Blue thingy!

    sorry guys. - yeah it's raining here.

    One of these days I'm going to have to go out and actually ride the motorcycle. I guess a little rain wouldn't kill me.

    Osram and Sylvania Silverstars are indeed different. Given the latter's blue coating, it is driven harder to achieve adequate light and consequently has shorter life. Blu coating is just kid stuff, best used on a Neon.

    At least you got the colours right.

    And to you, sir.

    Geez, what an oppionated group, but that's why I asked.
    Friday I ordered the Osram bulbs from Wunderlich along with the Micro-Flooter for the R1100S.
    Guess I should have responded earlier but I was busy RIDING!
    Oh, BTW, this is my 4th BMW which sits along side my '82 RS.

    Many "upgrades" we do to our bikes are illegal.

    They do make an HID that can work as a high beam and flash, they are Bi-Xenon units.

    I replaced the projector in my Ducati with one of these.

    http://www.theretrofitsource.com/pro...oducts_id=3181

    I was very happy with the performance of the unit.
    But it's also not an HID bulb in a Halogen fixture.

    I may keep looking for space for relays and balasts to fit one of these to my S as well

    The optics on the R11S are perfectly suited for HID lighting.
    To the best of my knowledge, bi-xenons are not a viable option on the 11S.
