Well I wanted my WR250X to have integrated turn signals in the rear LED stock taillight, and didn't want to pay $100 for the after market R1 taillight (WR250X and the '02 '03 R1 use the same taillight) so I cut open the stock taillight with a dremel and a fine cutting disk, and designed my own controller board, cut 4 traces on the board, and placed my controller board inside, then reseal the taillight with krazy glue, here are some pics, schematic, etc, my total project cost was less than $5... Controller Board Assembled Final Product I'll post up some more pics after I mount it up, I removed the huge tail section junk, and will be making a custom mount for this under the tail.
