RBA’s Guide To Lights

When riding at night, always make sure you can see and be seen.

Have you ever woken up early for a ride only to discover the sun hasn’t risen with you? Or have you ever been on a ride and told yourself, ‘Just a few more miles,’ only to find that the sun is setting faster than you can pedal? For safety’s sake, we don’t recommend riding extensively at night or during low-light hours of the day. But if you find yourself out past dark, taking part in a local after-hours crit or commuting home after a long day at the office, a set of lights will allow you to ride longer, be safer and open up a whole new world to your cycling experience. But first, here’s what you need to know before heading to the bike shop.

WHAT’S A ‘LUMEN?’
Bicycle light companies tend to measure their product’s power output in lumens. A lumen is part of the International System of Units and is a measurement of luminous flux. For practical purposes, it’s a measurement of the total amount of visible light emitted by a source, the ‘source’ being your bicycle light. Because a variety of factors go into determining the amount of lumens that a bicycle light produces, it’s best to check out your local bike shop’s selection of lights to get a sense of what 300 lumens looks like.
TO SEE OR BE SEEN
Bicycles lights can be broken down into two general categories: headlights that let you see, and taillights that let you be seen. Proper headlights are usually high-powered lights with at least 150 lumens of power output or more.
‘Lights that let you see are for your rides that begin well after the sun has gone down, and illuminating the road is your top priority,’ says Blackburn’s Jeff Titone. ‘Conversely, if your rides are primarily during the dawn or dusk hours, or on city streets, then visibility to automobiles is more important.’
The lights that let you be seen are typically more compact than the high-power headlights intended to help you see. ‘Be seen’ lights, also known as ‘safety’ lights, often produce far less power output, usually in the range of 20?100 lumens, and can often be found in a variety of colors. A standard setup of ‘be seen’ lights includes a white light up front and a red light on your rear, either on your seatpost or worn on the back of your helmet.
But don’t stop there. The more lights you have on yourself and your bike, the easier you’ll be seen. Also, note that most lights, whatever their intended purpose, typically have at least two modes of operation; ‘constant’ or ‘steady’ modes provide a continuous beam of light, while ‘flashing’ or ‘blinking’ modes produce a strobe-like effect, which is often more visible to motorists.
CHARGE IT
Whether you’re in the market for ‘to see’ or ‘be seen’ lights, you’re going to need a power supply. Two schools of thought dominate this area as well, with most lights utilizing either disposable or rechargeable batteries.
‘Even a simple, inexpensive ?blinky’ light can add a great deal of safety in low-light situations,’ says CatEye’s Bill Peck. ‘These inexpensive, blinky-type lights typically run on disposable batteries, like our CatEye Loop safety light, which provides up to 30 hours of run time in a constant mode and 50 hours in flashing mode.’
Most rechargeable light systems utilize micro-USB ports on the light bodies, which can be plugged into your home computer or laptop. Most manufacturers have found this system to be more user-friendly and efficient than having to plug your light into a wall socket for a charge. And while most rechargeable light systems involve an internal, fixed battery within the light body, some companies offer other alternatives. ‘Our lights use a USB-rechargeable battery that can be replaced,’ says Lezyne’s Patrick Ribera-McKay. ‘We call it ?infinite light.’ Additional batteries can be purchased separately for our three light options. So if you forget to charge your primary battery, you can swap it out for a fully charged one.’
MOUNT UP & ACTIVATE
‘Different lights are designed to attach to different parts of your bicycle, from handlebars to fenders, seatposts to bags,’ says Titone. ‘Some even attach directly to your clothing.’
‘Mounting flexibility is definitely key when selecting a light,’ says Sigma’s Gindi Orloff. ‘This includes looking at things like helmet- or handlebar-mounting options, the weight, size and profile of the light, as well as the light’s ease of operation. For example, consider whether or not the light’s buttons are easily accessible, or whether or not you’ll be able to operate your light while wearing winter gloves.’
In a perfect world, cyclists would always be easily visible to automobiles. But the reality is that during any time of day, particularly during hours of decreased visibility or at night, a cyclist is difficult to spot for a passing motorist. So do everyone a favor and get some lights-be seen and be safe.

SEVEN LIGHTS FOR YOUR CONSIDERATION…

CatEye’s latest headlight produces up to 250 lumens in its high-power setting, 140 lumens in its lower setting, and it includes a flashing mode. It can be recharged via your computer’s USB 2.0 port in a little over three hours, but perhaps its best feature is its ultra-wide beam, capable of lighting up a sizable chunk of the road ahead of you.

Four red LED bulbs light up the Flea Rear, which also sports both steady and flashing modes with six and 12 hours of run time, respectively.
