I know about the obvious stuff like a bright vest, blinking rear light and wearing light colored clothes but is there anything else that I need for when nightfall hits?
Make sure you have enough battery capacity to power your lights until your destination or use a dynamo and have a headtorch with you for backup. Your lights failing in the middle of nowhere on a cloudy night is no fun!
Go big on reflective clothing. Rather than having small reflective patches on your clothes or bike, you can get jackets where the whole garment is made of reflective fabric. When a car's headlights hit you that jacket will light up like the sun.
Front and rear lights, obviously. You can get lights that offer side visibility and get a front light with a cut off lens so you aren't blinding oncoming peoole.
You can get vests or jackets that are basically one big reflector. The brand proviz makes a ton of options, but you can find them cheaper. I had one from a brand off Amazon and had peoole come up to me to ask about it because it was so visible.
Ankle reflective bands are one of the best types of reflectors you can get.
Tires with reflective sidewalls are awesome.
If riding during dusk or dawn, wear high viz with reflective elements. High viz colours alone aren't very visible in the dark or by vehicle headlights at night.
Get retroreflectors. White pointing forward, red pointing back. You won't always realize when a light craps out, it's best to have passive backups. Get amber-colored retroreflectors that you can put between the spokes so you have sideways visibility. You can also buy reflective tape and wrap it around the frame.
I recommend clear safety glasses. Especially if you live someplace dry. You don't want dust or insects in your eyes. I hit a palo verde beetle once and it almost knocked my glasses off my face.
Eye protection is super important for daily bicycle use, no matter weather or time of day. A single speck of dust falling into the eye at the wrong time can cause a serious accident.
The more you ride, the higher probability of such thing happening. Not to mention wind drying your eyes, it can be serious pretty fast.
A lot of crashes are side impacts. So reflective frame tape or lights in spokes can help with side visibility. Some lights throw a little light to the side for this purpose as well.
Yeah, blinking lights make it more difficult to assess position and speed relative to cyclist, especially at night without street lights. At least get another one that shines all the time, or one that fades in and out but always shines at least a little, or a really good and big reflective one.
