Bicycle lights are a way to ensure your safety and comfort when riding a bike in the dark. Missing out on getting a high-quality tail light can lead to accidents and make the driving experience much less enjoyable. 

If your old tail light doesn’t offer the needed amount of output, has broken glass, or a different issue, consider getting a replacement. If you’re concerned that a replacement is expensive – the good news is, there are so many options on the market that finding a high-quality and affordable fit shouldn’t be overly challenging. 

This post is a full buyer’s guide to getting a bike tail light. If you interested in car Led headlights or in automotive led lighting in general, please follow these links. You will find out what the main characteristics to pay attention to are. Also, there will be a detailed review of some of the most popular models on the market.

Types of Tail Lights You Should Know

When you’re choosing the tail lights for your bike, make sure to explore all possible types and models. As a rule of thumb, tail lights come in three following models:

  • LED lights. These tail lights are well-known for durability and energy efficiency. On the flip side, LED taillights don’t have high intensity and might not be as distinctive from afar as other modifications. 
  • Xenon lights. Instead of using electric arcs, these lights rely on filaments. Brightness and intensity are the distinctive features of this tail light modification. Xenon lights are slightly more expensive than their LED counterparts. 
  • Halogen lights are the oldest and the most common type of tail lights. It’s a low-cost modification, small in size, and used by most cars, bikes, and bicycles. The low intensity of halogen lights can be inconvenient at times and is generally considered the downside of the modification. 

How to Choose Bike Tail Lights

When choosing tail lights, you will have to decide if you want to use the lights to see the surroundings or so that vehicle, bike, and bicycle drivers can see you. The former are usually larger in size and brighter, although the angle of the beam is quite narrow. 

The latter lights – the ones that allow other people to recognize your bike – are adapted to peripheral view and designed to be seen from different angles. They have a lower number of lumens, the lights are not as bright, there are fewer batteries. 

Another popular misconception is that you only need tail lights when it’s dark – studies and statistics prove otherwise. In fact, one of eight bike and bicycle accidents occurs during the daytime – that’s why you should od your best to increase your visibility at any time of the day. 

Most tail lights are described with a set of technical characteristics. In case you’re new to the market, these are the things to pay attention to when choosing a tail light replacement. 

  • Lumen represents the total amount of light the tail light is capable of emitting.
  • Lux – the measure of the intensity of the emitted light. Lux determines how far away the beam of light can be dispersed. The rule of thumb is – the higher the lumen is, the higher the lux will be. However, if a beam is narrow and directed to a certain point, the lux value can skyrocket even if the lumen is relatively low. 
  • Beam angle. This characteristic determines where the light is headed after it’s emitted – there are taillights that send the beam straight ahead or spread it as a bundle. 
  • Beam setting. There are different types of tail light beams – high, full, standard, flash, regular, pulse, and many more. When looking at models, you can compare different modifications and choose the one that suits your needs most. Keep in mind that ‘high’ or ‘full’ lights usually consume much more energy than standard modifications – thus, they are able to run for shorter time frames.
  • Burn time – the ‘battery life’ of a given tail light model. By this parameter, you will be able to determine how long the tail light will last before turning off. 

Other Factors to Consider When Purchasing Tail Lights

Naturally, there’s no one-size-fits-all when it comes to choosing the right model of bike tail lights. Depending on whether you drive on a highway, on a hiking trail, or another type of surface, you might want to adjust the selection of tail lights to fit your specific driving needs. 

Other than checking the characteristics of tail lights – lumen, type of beam, burn time, and others, the following points are worth taking into account as you make buying decisions:

Mounting options

Decide where you want to place your tail light. For some, attaching it to the seat stay is the best option since it provides the highest visibility level and will not slip or turn. Make sure you can control how tightly the tail wheel is mounted and adjust the tightness level freely. A solid practice to follow is to look for a model with interchangeable mounting straps – it grants your tail lights higher durability.

Other than that, take into consideration what exactly you’re bounding the tail light to – aluminum or carbon. For the latter, consider opting for a tail light with a rubber strap that stretches freely. It’s a much safer mounting method for carbon frames than a traditional crew-and-bracket. 

Battery

Most tail lights are USB-rechargeable – some, however, will still require batteries to run. At a first glance, getting a USB-empowered battery seems like a more expensive option – however, in the long run, it’s likely to save you a lot of money since there will be no need to pay extra for battery replacement. Also, such modification is easier to maintain and convenient. 

If you found a model that requires a battery pack to be plugged into the light, make sure you can effortlessly mount it onto the bike without worrying about it slipping from the surface. Although it may seem inconvenient, an option with a battery pack is actually one of the better modifications to get out of all options available, all because it balances out the weight of the light preventing it from moving side to side as you drive. 

Brightness

Lumen seems a descriptive characteristic of the brightness level of a tail light. However, the fact is, it doesn’t offer enough conclusive data as to how bright a given light model will be. There’s more to determining brightness than lumen. 

A reliable way to test the brightness of a bike tail light is to move it down and ensure it doesn’t blind you as you drive. If that’s not the case and you struggle to see the road, the modification is too bright and needs to be replaced for a dimmer option. 

In case you are worried that not having a bright tail light ill make it harder for everyone on the road to differentiate you from street an city lights, as well as car tail lights, consider setting the light into the ‘Flash’ mode – this way, you will be distinctly different from other traffic sources on the road. 

Reviewing Top 7 Bike Tail Lights to Help You Make the Right Choice

Finally, to help you navigate the waters of local bike shops and online stores, we decided to review the most popular models, describe their pros and cons, and give you a better understanding of how to choose tail lights for a bike the right way. 

We have personally tested all the options described above and have an informed opinion about their performance. Let’s get started. 

Cygolite Hotshot

Cygolite is an LED-based tail light. There’s a 2-watt lamp that empowers it. The model is USB rechargeable – you will not have to replace the battery when the old one is worn out. The unit offers five modes that drivers can benefit from – steady, zoon, triple, single, and zoom.

The running time for Cygolite Hotshot is 4.5 hours – not too impressive but will do for a hiking trip. The seller claims to use on-site programmable smart technology for mounting adjustment – that’s a convenient feature as it allows to adjust the speed of light emission. 

Pros Cons
• Bright and makes the bike easily
noticeable
• Easy to mount to the seat stay
• USB-based charging
• Quickly drains the battery
• Challenging controls – figuring out how to turn
it off and on will take a while
Garmin Varia RTL 510

This unit wins its counterparts over with long-lasting battery life – as a matter of fact, it can run for up to 15 hours straight. All the other characteristics are solid – you have the lumen of 20, the 29 night flash, and 65 day flash. The model fits most bikes and bicycles and is easy to mount. 

Garmin Varia RTL is one of the few tail lights that offer a solid level of daylight visibility. Drivers will be able to notice the bike from a mile away from the angle up to 220 degrees. One of the inconveniences the model makes drivers face is having to purchase a dedicated radar display to use the tail light freely. You can hook the unit up to any radar other than the seller’s own device, sold separately and not included in the cost of the tail light. 

Pros Cons
• Bright light
• Flashing mode
• 15 hours of battery life
• Daytime visibility

The seller includes a range of nice-to-have bonuses to the package – a backpack clip, spare batteries, and a seat post mount. There’s a lifetime guarantee as well which will give you more confidence when using the tail light. 

The bad news is having to replace the batteries regularly since it’s not too convenient and quite expensive in the long run. 

Pros Cons
• 50 hours of battery life
• Lifetime warranty
• Water-resistance
• Having to change the batteries regularly
• Switching between modes is challenging
