    Nice work, and it's good to have the info on the /5 gauge bulbs.

    Down the road I think an SM-1 would work as a flasher relay? This is the three spade Kisan flasher.

    The Kisan looks nice. Looks like the full setup for four turn signals plus the relay would run about $200: $25/each for signals plus $107 for SM-1.

    I imagine it's also possible to make a relay up with whatever functions you wanted. I found this instructable. I think i'm going to try it out before I drop the $$$ on a Kisan.

    Turn signals flash at a normal rate, no "fast flash", with the stock signal relay:

    Sorry, out of focus. I await the arrival of my Kisan SM-1; more bad pictures to come.

    I love my Beacon 2. It puts out tons of lumens. Are the turn LED signals any brighter than the incandescent lamps?

    Short answer is YES.

    Between the 18T and 45T bulbs (18 or 45 LEDs each bulb), the 45 puts out a LOT of pure colored light. Even the 18 LED varieties put out more light than an incandescent.

    Only the really cheap non-tower, Autozone type 6-8 LED bulbs put out less light than a regular bulb.

    If you love the Beacon, you'll love the SBLEDs.com 18T or 45T bulb options.

    + 1. The 1156-x45-T's are BRIGHT. It is hard to judge from the pictures, but they are much brighter.

    I think I'm missing something here. Did you not change out your charging system indicator bulb with a Red LED? From the looks of it, it's a BA9. Is that correct?

    No, I didn't replace the charging system indicator with a red LED. There were some posts earlier in this thread about why an LED will not work there, as I recall. I left the incandescent bulb in place.

    *EDIT* Found the post:

    Killer, thanks for that detailed write up. I just changed out all my LEDs (except the charging light) and it all works great :D

    Here is a Kisan signalMinder SM-1:
    [​IMG]


    These are the connections for an SM-1 on a '75 R90S. This is the stock BMW (Hella) relay and the Kisan signalMinder SM-1; Hella relay has four terminals and the SM-1 has three:
    [​IMG]

    This is the BMW "plug". Four wires: brown is ground, black/white goes to instrument cluster turn signal lamp, green/black is positive (+) power to the relay, and green/yellow is power output to the turn signal switch:
    [​IMG]

    Can't use the BMW plug, so, out come the wires. I was able to remove two of the female connectors but had to cut the wires on the others:
    [​IMG]

    Attached a new female connector to the green/black, then the BMW wires are connected directly to the SM-1. The SM-1 instructions show an example of a "plug" so I transposed that to the SM-1 connectors. Look at the photo for the correct connector locations: 1) green/black, bottom connector in photo; 2) green/yellow, middle; 3) brown is at the top:

    Just wanted to send a note of thanks to Kisan LED techs. After installing aftermarket LED's in all four indicator lights my lights would all flash at the same time. I purchased a #168 LED instrument indicator bulb. The tech told me to remove the indicator bulb to correct the all indicator flashing. It worked and I am now waiting for Kisan to send me the #168 LED bulb. Wonderful to have a good company offer suggestions without actually purchasing anything of significance. If and when I learn to post pics they will be there.

    I did not reconnect the black/white wire (power to the turn signal lamp in the instrument housing). Notice in the photo below that the green/ black and brown wire positions are switched; this is not correct. The correct connections are shown in the previous post.

    These are the connections for the running lights and the brake lights:
    [​IMG]

    I ran the red wire out of the headlight shell to the brake light wire (green/red) underneath the tank:

    SM-1 red wire to BMW green/red brake light wire:
    [​IMG]

    I cut the SM-1 black and white wires and attached female connectors:
    [​IMG]

    The SM-1 black goes to the left turn, BMW blue/red; the SM-1 white goes to right turn, BMW blue/black. I connected the SM-1 wires directly:

    You are correct. The stock BMW has one turn signal indicator lamp in the instrument housing. The LED is necessary to prevent "cross-talk" between the right and left turn signals. I have an Acewell speedo with separate right and left lamps, so I did not connect the black/white wire (power to the BMW turn indicator lamp).

    You are too kind, but thanks for the compliments. How are your projects coming along, Les_Garten?

    I've upgraded to a Hannigan Fairing which uses non-BMW turn signal housings and and I find that these front turn signals are not bright enough to suit me. I want to do an upgrade to LED turn signals and plan to use the Custom Dynamics Genesis LED Cluster:

    http://www.customdynamics.com/motorcycle_led_bulbs.htm
    (first item on the page)

    The usual rule of thumb that I've always heard is to use an LED to match the lens color: a red LED for a red lens, an amber LED for an amber lens. But White LEDs have a much higher brightness than the Amber LEDs (9500mcd as opposed to 3500mcd) and I'm wondering if I can use the White LED cluster behind an Amber turn signal lens. I've done a quick check shining a white LED penlight through an amber lens and comparing the "tone" of the light with an Amber LED marker light shining through the lens and the two light sources look the same.

    Bill, I have the signalMinder and now have rear turn signals as running lights. It has been rumored that rear running lights must be RED according to law; don't know if that is factual but I went with red LED's in my rear turn signal housing and they shine brightly as RED through the amber lens. I went with amber LED's up front and they shine brightly as amber, of course. I suppose one could try a "white" LED with an amber lens, but the $$$ cost of one LED is the factor in a trial.

    in california at least, this is correct. I think it is nation wide.
