Should Bike Lights Be Flashing?

There are a few schools of thought on this subject. Some people think that bike lights should always be flashing, day or night, while others believe that they should only be used when it’s dark out. And still others believe that it depends on the situation.

So, what’s the verdict? Well, there isn’t really a definitive answer. It ultimately comes down to personal preference and what you feel comfortable with.

If you’re someone who likes to err on the side of caution, then you may want to keep your bike lights flashing at all times. That way, you’ll be sure to catch the attention of drivers, no matter what time of day it is. And if you’re riding in an area where there isn’t a lot of street lighting, then having your lights flash will help you stay visible.

On the other hand, some people find constant flashing lights to be annoying and distracting. If you fall into this camp, then you might prefer to only use your bike lights when it’s actually dark out. That way, they won’t be constantly shining in your eyes and making it difficult to see where you’re going.

Ultimately, it’s up to you to decide whether or not you want your bike lights to flash.
