I know there is history on this subject. Reading that history prompted me to replace my marker/running lights on my 2009 650R. Just to state the obvious, I am talking about the little lights above the headlights.
I am just so excited about how easy and inexpensive it was to do that I had to create a new thread.
I learned from existing postings that the bulbs needed for the running lights are T10 wedges. Various people refer to some websites that sell these bulbs. Well I bought mine on eBay for 3.99 shipped for the pair. I am not affiliated with this seller. This is a link to the bulbs I bought. 2pcs Xenon White T10 Wedge 5 SMD 5050 LED Light Bulbs 192 168 194 W5W 2825 158 | eBay
If you check that seller's feedback you'll see that 'rbgiantfan' posted. I'm sure other sellers bulbs are equally awesome but I am posting this as a very reasonably priced option that is guaranteed to work. Shipping was very prompt from California to NY. (Now I as I look back I'm not sure if he/she is selling more)
The difference is amazing. The light is so white and bright compared to the stock bulbs. Sorry I was too lazy to take pictures but I was so excited to try the bulbs that I just popped them in. Hey, for $3.99 you can take a chance. :-) You will not be disappointed.
Also, as stated in earlier posts, it is super easy to replace these bulbs. No fairings to remove, just reach up under the front cowl and feel around for a rubber housing with wires coming out of it. Wiggle the rubber as you gently pull it out (heh heh). Don't pull by the wire.
Lastly remember that LED bulbs have to match polarity with the wires so if the bulb doesn't work, flip it around and try again (test it before you push it back into the bike).
Have fun !
