This is the fixed-gear that I ride to work everyday. It is a simple build on purpose; no fenders, packs, gears, or rear brake. I went for this setup because wrestling an unloaded bike onto the light rail’s vertical racks and up the stairs at work is easier. You can see the NiteRider headlight on the front. It’s small and lightweight. A good friend gave it to me for a birthday present, I would tell you who, but he said he wants to remain anonymous. The light is pretty darn bright, but I’ve seen other cyclists with super bright lights and I always wonder if mine is as bright as their’s. Lumen envy, I guess. In any case, I notice it gets driver’s attention best when it’s in blinking mode. I usually have it on blink, unless I pass through a place where the street is really dark, at those times I need to look down for pot holes and the combination of pitch-black and blinking can make me a little seasick. The main trick with the light is to remember to bring the battery upstairs with me when I leave the bicycle in the garage overnight so that I can charge it. Oh yeah, the other main trick is to remember to bring the battery back downstairs the next morning.
On the rear, I have two sets of blinking red lights, one is a really bright with a combination of white & red in weird combinations and the other is a some blinking red LEDs, that by now are quite old fashioned. They seem to do the trick though.
I’d also like to point out the small tool bag attached under the seat. It is a square of duck canvas sold by Rivendell Bicycle Works called a “Burrito Wrap“. It contains a spare tube, patch kit, spoke wrench, and multi-tool. It’s held on to the bike with a strap used for pedal clips.
The lock was added yesterday as described in this post.
I use SPD style pedals and although this means wearing special shoes to work, I chose them so that I am using the same kind of pedals on all my bikes. I do this so that no matter what bike I have my pedals disconnect by the same method, especially handy when the disconnect is urgent, like when I’m about to fall. I keep a couple of pair of shoes in a file cabinet next to my desk to change into when I get there. One black the other brown, so I’m set up no matter which belt I wore that day. 
I carry my laptop, glasses, keys, and bicycle pump in a chrome messenger bag. It’s like this one but a different color and mine is more beat up by now:
Sometimes I hang a coffee mug clipped in with a carabiner through a loop of webbing on the bottom of the bag. I probably shouldn’t have bought such a big bag, but there it is.
My Uncle “Unc” Steven , drove all kinds of big-rigs for 34 years. Between that and talking to the truckers in the early 70s on Citizen Band “What’s your 20, good buddy?” radios, I’ve always liked the 18 wheelers. This morning I came up to a red light a SYSCO Reefer just to my left (he in the right lane me in the bike lane). I took off quickly so I could get ahead of him and then watched carefully in my rear-view mirror to see if he was going to try to pass me. While there is 3 feet of bike lane, and I trust a professional driver over the morning commuters, I still kept a close eye on him. As he got going (very slowly), I saw him put his right signal on and pull into a driveway behind me. Whew! No passing, but I said “Good Morning Unc” to the driver.
