Recently I spoke with 2 riders who said they simply do not ride at night because they are concerned ab out visibility and not being able to see deer on the road (apparently where they live this is a valid concern).
While I do not do a lot of night riding myself, there are a few things you can do to make this a bit safer.
1. Ride with other people who live in the same area.
2. Add additional lighting to the back of your bike. I know this is not always easy to do, but trust me if you really want it you can find a way to add it.
3. Also where deer are concerned, you can add a deer whistle to your ride. This is good for either day or night. I have had one on all my bikes and have seen deer stop and go the other way because of it. You can find a nice small one that can easily fit any bike on amazon at https://www.amazon.com/Living-Products-LLC-0001-Save-A-Deer/dp/B003XNGLJU/ref=sr_1_3?ie=UTF8&qid=1470252675&sr=8-3&keywords=deer+whistle
4. Do not over ride your headlight. Many people say this but I am not sure everyone understands what it means. Simply put it means slow down. You should not being so fast that you arrive at the very edge of what your headlight is showing you before you have time to process what is there.
5. Wear reflective or bright colors so that you are easier to see. Dark colors tend to allow you to blend into the darkness and the surrounding environment at night.
Remember Ride Hard, but always Ride Safe. Always be aware of your surroundings and remember it is ok to slow down.
