It was my first commute home in the dark today too. I found it quite an invigorating experience - it made my now familiar commute a totally different experience.
I ordered a Hope Vision 1 on Sunday which should be delivered to my work tomorrow, ready for the ride home. It will definitely be useful as the last half is on unlit roads, and I was actually grateful when cars came up behind me! Wasn't too bad around 13-15mph, but any faster and I was getting a little uncomfortable with the lack of forward vision...
When it arrives tomorrow my current light will be utilised as an extra flasher.
My other big concern was being seen from behind - I wasn't confident that my current light was bright enough in commuter traffic. So I walked to a LBS to try some out and picked up the
Smart Lunar R2. Stupidly bright, miles ahead of my current poxy rear light. Felt a lot more confident with that strapped to my rear for the journey home.
Other than that, the only addition I made was attaching an LED to my helmet - I usually have an LED on my rucksack anyway.
We'll see what tomorrow brings.
