My main commuter these days is my Dahon MU P24.

I have a Cat Eye EL320 in front as a blinker, and a EL170 back-up blinker near the front fender. On the handlebars, I have two Fenix L2Ds on steady. My helmet has a Fenix P2D on steady, and a Sigma red blinker on the back.
The rear red blinkers are a Cat Eye LD610 on the rack and a Maxxon Wireless Brake Light under the saddle.
I commute to work with either a Topeak DXP trunk bag velcro-ed and bungie corded to the Dahon touring rack rack, when I need to carry my DSLR and for light luggage days. And when I need to carry my Macbook, I use a pair of yellow Ortlieb Back Roller Classics.
For mirrors, I use a Zefal Spin on the left side and a Zefal Dooback on the right.
I also have an AirZounds 2 horn, a really critical piece of kit riding on our roads.
