Here are a couple of pictures of my bike. I replaced the handlebar bag on the picture for an Arkel, the rear panniers are waterproof Seratus and the front are 10-12 years old Arkel (I don't use them very often so they look brand new).
The bike is stock except for the new inline brakes and tires and the triple layer of handlebar grip.*One day I'll swap the large crankset for something smaller, but I already blew my budget for this year and plan on cycling mostly on relatively flat terrain this year.
I like the way I placed my headlights and blinkies... but to be honnest, it is mostly for esthetic reasons... one blinky and one good headlight would have been as good.
I also placed hooks on my rear rack. No need for hooks on my panniers and it is now much easier to instal them on these racks.
