i dont have any pics to share but i did this mod and mounted the lights on the sides of the 'yamaha' plastic below the hood. i would have to say these lights are 25-50% brighter than stock. 50% may be a little steap, but 25% or more for sure. not to mention it looks way better and is a cheap simple mod. great post man! rep to ya.
note to those that are gonna do this mod, unless you mount the lights on your handle bars the light wont turn with your wheels, so you might wanna keep your stock light if you ride trails in the dark.
