Why Should I Get a Bike Helmet Rear Light? Is It Legal?
The primary reason why you should wear a bike helmet with light is to stay visible on the road. The light helps other road users see you from a distance as the light shines bright.
Also, the light comes in handy when there is reduced visibility on the road. The reduced visibility could result from bad weather like fog and heavy rain or low light.
However, you should note that relying solely on the light for nighttime vision on high-traffic roads is illegal. That’s because these lights can be extra bright to confuse motorists into assuming you are far when you are just a few yards away.
So, in most cases, these lights are best left for off-road users, and if you have to use them on the streets at night, you have to use them sparingly.
But to ensure that you are safe on the road and are not a distraction to other road users, you have to get the purchase right. Below is a guide to help you do that.
Buying Guide for the Best Bike Helmet Rear Light
Consider the following when shopping for your biking helmet rear light:
- Light Type – Static Vs. Flashing
The first consideration for picking a cycle helmet rear light is the light type. Typically, the lights come as static or flashing.
Static lights are brighter to make you visible from a distance. They are, however, not as battery-efficient as flashing lights.
So, if you want more battery runtime and still be visible on the road, consider flashing lights.
- Illumination (Lumen)
For you to know how bright a helmet light is, you have to check its lumen. The lumen is the measurement of light brightness, and the illumination can range from 100 lumens to over 1000 lumens, depending on the brand.
If you want more brightness, you have to go for more lumen.
- Lighting Technology
When it comes to lighting technology, you are likely to find halogen lights and LEDs. In terms of brightness, halogen lights are the brighter choice.
However, they tend to consume a lot of power, and so the battery runtime is lower. If you want an energy-saving helmet mounted bike light with reasonable brightness, go for LEDs.
Besides, you don’t have to shine so brightly on the road as that will confuse motorists.
- Light Modes
You should be able to adjust the brightness of the helmet light depending on the surrounding. That’s why going for a helmet light with multiple modes is advisable.
Consider at least three light settings for the best performance. Prioritize on the flashing mode as it makes it easy for far motorists to see you.
You must consider how you’ll mount the best bike helmet light. Some rear helmet lights come with adjustable straps and others with plastic mounts.
There are also a few others that require the use of an adhesive. Overall, those with adjustable straps are the best, in my view. Their mounting and dismounting are generally seamless.
Some helmet lights come with disposable batteries. However, a majority of them use rechargeable options.
I think the rechargeable ones are a better option because they are cost-effective. In most cases, you get to charge them using a regular USB charging cable.
Of course, the more battery runtime you get, the better it is for you. While there’s no standard battery runtime, anything above 12 hours is decent.
Do you plan to use the helmet mount bicycle light on urban or rural roads? If you are targeting the latter, consider a light with 100-300 lumens.
Since there are street lights on urban roads, you don’t need so much brightness. You need more illumination on rural roads, and that’s where you should target at least 600 lumens.
However, if you are an off-roader, you need more brightness and as a result, target at least 1000 lumens.
- Waterproof Construction
Given that there is always the chance that the rain may catch you on the road, your helmet light should be waterproof. You wouldn’t want the device to become faulty as soon as it’s rained on.
There is also mud, which is typical of off-roaders.
The helmet light should come in a waterproof construction to withstand all wetness.

Why Should I Buy A Bicycle Helmet Rear Light?

You should note, however, that its usage is more preferred off-road where the traffic is low.
Is It Legal To Use a Helmet Light at Night?
Off-road, it’s not illegal to use a rear helmet as it improves your visibility. However, it’s illegal to use it at night on a high-traffic road as it may confuse other road users.
What Type of Helmet Right Is the Best?
Consider flashing lights as they are bright enough for easy spotting on the road. They are also more energy-efficient and have a more extended battery runtime.
What’s the Safest Illumination for a Helmet Light at Night?
It depends on where you are riding. If it’s on urban roads, anything between 100 and 300 lumens will do.
However, you’ll need 600 or more lumens for the urban roads and at least 1000 lumens for the off-roads.
Without a doubt, you are safer cycling with a bike helmet rear light. It provides you with visibility under low light and when the weather is so bad.
