    I recently purchased an '03 KTM 640 ADV and have been in early Christmas mode, adding various components to the bike. One of which is to replace the OEM brake light with an LED bulb. I've read information online about LED replacement bulbs and their claimed advantages. I purchased a bulb online and decided to take some photos to determine if there is any significant difference. I thought that others may find the results interesting, I won't state my own conclusions within this posting.

    I purchased a DC12V 1157 LED bulb to replace the 12V 21/5W OEM bulb. I chose this particular bulb because the placement of the 13 diodes around the assembly appealed to me more than other LED brake light replacement bulbs that I found to be available.

    Here is an animated GIF file showing the daytime illumination of the brake light housing before and after, photo angle taken from the back of the bike.

    For those of you who don't like animated GIF files, here are static versions of the above:

    I wanted to have a visual reference for the actual light output, so I closed the garage doors and took another set of photos with both bulb options illuminating the interior of the garage doors from about 12" away (the bike was on its center stand for all photos).

    I too am in the market for a LED tail light for the ADV. I am not interested in the LED for the light output I am interested in it for its toughnesss. LED light wont break its filiment like a standard light when hitting whoops or taking serious offroad trails...

    I am gonna get the LED light on the Trail Tech website.

    FYI... I bought an LED 1157 replacement because regular 1157's didn't last long at all. Well the damn LED didn't last much longer. The bulb broke loose from the brass(?) base of the bulb. I bought an 1157HD from Advance Auto Parts and it's still going strong.

    That looks like the exact same bulb I bought 2 of on ebay.

    It didn't fit my Concours due to the shape of the reflector. The square vs tapered base of the stock bulb was the problem.
    I always plan to try it in the 650GS & see if it fits, but just lazy I guess.
    Since it does indeed appear to be brighter (some LED aren't), I'll have to give it a shot.

    Looks like a fairly bright bulb with good color.

    Thanks for putting the time and effort into the fancy graphics SR... very informative.

    I bought the LED bulb on eBAY as well, a set of 2. Most likely from the same seller.

    Thanks Creeper, I appreciate the feedback. I've gained so much information from others on this board that I thought I'd do something in return.

    The seller that I obtained the bulbs from has an eBAY store... http://stores.ebay.com/Automotive-Lighting-Strobes. Look under the "LED Signal Brake Bulbs" store category there. I just checked and didn't see a red 1157 listed, but there is an amber one. I imagine that if you contact them they'll have the red ones.

    I got mine from TDILEDTECNOLOGY through ebay.

    Contact is tmi61@aol.com


    Or just go into ebay motor and do a search for 1157 LED RED or 1157 LED.
    You should find what you need.

    I went through this myself. If I took an all day ride, the tail light would be out by the time I got home. I got the 1.85" cluster from Custom Dynamics with a wire pig-tail. I glued it to the inside of the tail light (had to cut it open with a dremel) backed up with a tie-wrap and cushioned with part of a beer can cozy. The pig tail was soldered into the taillight wiring harness. Since then, no problems, and that light is very bright, both on tail-light and brake-light.

    After following the instructions for tail light bulb replacement, I twisted the bulbous cover under the rear fender 30 degrees like it says, pried a bit with a flathead screw driver but still can't get the cover off.

    The cover feels loosest when the flat lips of the cover are parallel to the ground but with a gentle prying, the cover still won't come out.

    What gives?

    Who knows the trick?

    That's 30 METRIC degrees, Dirty. To convert to SAE, multiply the 30 by .976554.

    Doggoneit!

    I'm only used to working in cubits.

    Anyone know the conversion factor for metric degrees to cubits?

    Dirty's come to a screeching halt!

    Yeah, getting that rear bulb in can be a bitch. Sometimes it slips in right away, sometimes it takes forever!:rofl
    BTW, I replaced that little F@#$%& with one of these:

    3 watt Luxeon LED.
    Expensive, but CNC'd aluminum and a little brighter than stock. Hopefully last longer on the paint shaker.

    Great link, most all of their bulbs cost less than 'Stich's closeout LED 1157 replacement bulb.

    They had very fast delivery too. About 2 days with standard
    USPS shipping.

    I found a pair of leds at the auto zone and the one I put in works fine, worth every penny not to have to replace bulbs all the time.

    To get the "bulbous cover" off and get at the light I put a flatblade screwdriver under the side lip and press in towards the center and the rubber squishes in until you can get the screwdriver all the way under the cover and pry it out.
