In fact, the motorist coming from the same direction of the cyclist at night or in poor light condition can notice his/her presence on the road only through the light coming from the red reflectors on the back of the bike.

Importance of bike tail light

According to various reports, people all over the world have increasingly started using brighter tail lights after being inspired by various safety programs for bicyclists. In my opinion, the bike tail light is the third safety feature after the helmet and headlight. As you already should know wearing a bike helmet is obligatory in many states in America.

The main purpose of using bike tail light is the safe identification of the biker by the motorist and other bikers coming behind him/her in the same direction as this light improves their visibility to the motorist as well as other bikers.

Things to consider while buying bike tail light

You can find various types of bike tail lights in different sizes, styles, and color in the market which makes it difficult to find the best one. While buying the best bike tail light you should consider certain factors, discussed briefly hereunder.

Brightness: The first thing to consider while buying a tail light for your bike is its brightness so that it can be seen easily. Most of the modern tail lights contain LED bulbs to make them brighter but their brightness also depends on their wattage or lumens as well as the quality of the LED bulb. The brightness of the tail light is equally important to its style. LED bulb of 1 watt can provide superb brightness to your bike tail light.

Battery: The second important thing to be considered in this regard is its battery. The brightness of tail light also depends on its battery. You can use some of the lithium batteries used in watches and flashlights for up to 100 hours or use AAA or AA batteries to light 1 watt LED bulb for up to two days on full beam. You should choose batteries for your tail light depending upon your traveling in odd hours. Actually, you can also opt for rechargeable batteries to use them for a long time. In general, the best bike tail lights include rechargeable battery instead of AAA or AA batteries.

Mounting: Today bike tail lights are available with different types of mounting options and styles like clamp mounts or band or strap mounts. Strap mount tail lights are commonly used as they can be mounted easily on the seat post without using any tool. But if you choose heavier light for the back of your bike then you should opt for clamp mounted tail light.

Quality: Though you should look for the best quality tail light for your bike it should also be affordable for you. You can increase the brightness of your tail light by using the bulb of better wattage.

So you can choose the best bike tail light depending upon the conditions in which your ride and your riding style.
