With all the options available, it can be challenging for a biker to choose the right rack mounted rear bike light. But there are factors to consider to find the right product. Please see below.

Power Supply Option

A rack-mounted rear bike light is either battery or rechargeable. Each of the power supply options has upsides and downsides. If you are using a rechargeable type, it is very easy to recharge the bike light, but this type is costly.

On the other hand, battery-operated bike lights are more affordable, and there is no need to recharge the battery every time you plan to ride your bike. The downside is that you will keep changing the battery once the power is drained.

Light Intensity

Make sure to look for a rear bike light with enough light intensity to make you visible while on the road. But be careful in choosing the brightest one since it can also affect the view and the eyes of outer road users.

Lighting Settings

Another factor to consider is the available light settings in a particular rear bike light. Most of these products come with flashing or steady lighting. It is recommended to look for a rear bike light with multiple settings to provide versatility.

When a rack-mounted bike light is versatile, you can easily adjust the intensity of the light depending on the current road condition. The switchable light setting also allows you to choose a light setting of your preference.


The rack-mounted rear bike light design is also essential in giving the best light output from your bike. Look for a design that offers better light output and enhances the biker’s visibility when on the road.

Look for a universal design that allows you to position your bike on the rack and other parts of the bike. It is also preferred to look for a lighter and more compact design for convenience usage.
