What Factors to Consider While Buying Best Rear Bike Lights?
There will be tons of different factors to think about when getting one of these. If you aren’t well-versed about taillights or bike lights in general, then you will love this brief guide below.
We explain everything you need to consider if you want the best rear bike light. For those who don’t want anything less than that, this guide will help them enormously:
If there’s one factor you should never overlook, then that’s the brightness level. This will tell you how bright the light can be, so you’ll want to for the highest measurement possible.
Brightness is measured in lumens, and taillights are usually not the brightest of lights. But you should get no less than 20 lumens for a bright-enough experience at night.
If you’re only riding in fogless areas at night, then a 5-lumen light will suffice. If you want maximum brightness during the day, then choose nothing less than 50 lumens.
It is important to note that lights with more lumens also consume more battery. So if you’re going on long trips, lower lumens could be a better choice.
Like said before, you will find that rear bike lights with tons of brightness will consume a lot more energy. So a 50-lumen light will probably last between 3 and 6 hours while a 5-lumen model may last 24 hours or more.
If you’re a long-distance biker who tends to ride for several hours at once, then you may want a long-battery light. These will probably not be as bright as their less durable models, but will certainly last the whole trip.
For about 10 hours of constant use, you should pick a Li-Ion battery of at least 300mAh. Be sure they are rechargeable batteries for the highest convenience. You don’t want to be buying batteries every time they run out of energy.
Type & Shape
The bulbs on the lights will also make a huge difference. But this is something easy to pick. We recommend nothing less than LED lights for the best experience.
Halogen and incandescent lights are not good enough anymore. And simple reflecting bulbs are not necessarily the smartest option (some people drive without lights on).
So in terms of overall brightness and power consumption, nothing beats a set of COB LEDs.
Apart from the bulb type, the shape also matters. We usually recommend strip models over rounded ones, as they are slightly more visible. But it all comes down to your needs, as round models can fit almost anywhere.
Durability & Materials
While the LED is what emits the light, it needs a chassis or casing for protection. This is where you need to consider the materials and overall construction of the piece.
You will find that most of these lights are made with high-quality plastic exteriors. But the best one will come with aluminum or similar metal casings.
These are the ones you should consider for their ability to withstand impacts and shocks (in case you fall while riding).
If you find a light with a rating of IPX5 or higher, then that’s an excellent piece to consider for its waterproof and dustproof build. So you can ride safely anywhere you go.
The last thing you should be careful about when choosing is the practicality of the mounting system. There will be several to consider.
For example, a bolt on the rear bike light will need you to use tools, screws, and the like. But they will stay on the bike for a long time, so you won’t need to worry much.
Another design is the tie system. This is a type of light you need to hook up to your seatpost or saddle using ties. This is excellent and reliable, but it can be problematic to take off when necessary.
And the ones we recommend the most are the strap models. These may come with nylon or rubber straps that you can stretch and attach to seat posts, saddles, racks, or even helmet hardware. They stay firmly in place and don’t demand much work to use.
What Lights Do You Need on A Bike?
There are two types of lights everyone should have on their bike. One would be the headlight. This is the most practical light you can have, as it will light up your path.
The second is the rear light. Also known as the taillight, it will let people behind you know that there’s a bike on the road. This is an essential bike to have.
But there are many other lights you can get. Some lights attach to the frame or rims of the bike, making it even more visible during the night. And others may even work on your helmet if necessary. These are not critical but can be pretty useful to increase your safety.
How Many Lumens Do I Need for Bike Rear Lights?
There’s no specific rate of lumens to go for. This happens because lumens are not the only measurement you should consider when it comes to taillights.
For example, a 70-lumen light will be bright enough to illuminate even on rainy days. But it will probably run out of battery fast.
Similarly, a 10-lumen light may not be bright enough to work safely in foggy environments. But it will probably last over 10 hours.
So it depends on your needs. Overall, we recommend getting as many lumens as possible if you’re looking for maximum visibility. But if you only want decent visibility and instead prefer durability, then a low-lumen light would be ideal.
Frequently Asked Questions (FAQs)
Sure, you went through our reviews and learned a ton with our buying guide. But we’re pretty sure there are still some doubts in your head about rear bike lights. Below, we have some questions with their answers that may get relieve those doubts:
1. Why do I need a bike rear light?
Obviously, you need a taillight for safety. But it is not only that. Countries like the US and Canada have laws against people who ride bikes at night without lights. And in some countries, you may have a specific brightness level to match. So why do you need one of these lights? To prevent a fine or worse.
2. Where to put the rear bike light?
There are tons of different places to put them on. We usually recommend just below the saddle or seatpost. But you can also install them low on the frame, saddle, or even the back of your helmet.
3. How do I mount the rear light on my road bike?
Road bikes come with a slightly shorter seatpost, so it is usually better to set them up on the saddle directly.
For that, however, you will need a saddle or a strap design for versatile mounting. Overall, though, you can set them up in the same way and place as in a mountain or commuting bike.
4. What type of rear bike light do I need for off-road biking?
A rear light for an off-road bike needs to be ultra-bright. Remember that off-roading you won’t have the same illumination as in streets or highways, so it is essential to have maximum brightness.
At the same time, you want a high-lumen headlight. This is the most important one to have. We recommend models with at least 500 lumens of total brightness. If you can go over 1000 lumens, that would be even better.
5. Should I use a rear light during the day?
Yes, not only should you, but you must. Most accidents involving bikes happen in the day. And there’s a high chance they happen because drivers don’t see the biker on the road.
So it is heavily recommended to also have them in daylight, especially if close to sunset or sunrise time.
It won’t be easy to find a rear light for your bike that gets the job done if you don’t know what to look for. But with this guide, you shouldn’t have much of a problem.
With our list of the best rear bike light reviews, the buying guide, and our FAQ section, you should have no problem picking the right one.
