I just thought to mention it, as I am really impressed with visibility of yellow lights. I have DM denali on two of my bikes, where you can change the lenses, and they have really penetrative light, even though they are so small. But in V300 I just fitted cheap Chinese yellow axillary lights and they work great. Anyway, not only the yellow lights are much more visible but also less annoying to other drivers. I recently went for a trip with my friend, and it was so easy to see her when looking into the mirrors, even though she was several km behind.
