Topeak RedLite Aero rear light
8 10

If you want a low-profile, fit-and-forget light for your road bike then the Topeak Redlite Aero is a good choice. Its output won't be melting any eyeballs but it's simple to fit in a variety of positions with a good field of vision.

The Redlite Aero couldn't be simpler really. Crack it open to put in a single AAA battery and turn it on, and the three LEDs will flash in the single blinking mode for a claimed 80 hours, or run constantly for 40. Mounting is a simple rubber strap with a loop at each end, which locates on a mount either side of the light; the rubber foot keeps it from moving about.

Two mounts are included, one that's designed to go around a seatstay and one for a seatpost. The LEDs are angled so that they're pointing about straight in either position, depending on which way up you put it.

It's not the brightest light out there by some margin, but it's plenty bright enough to be used as a standalone rear light on your bike, and the LEDs have a very wide field of vision thanks to the design, so there's plenty of visibility from the sides. The mounting means that the light hardly protrudes at all from the sides of a seatpost, which will be good news if you find your thighs clipping bigger clamps. And if it's still an issue you can bung it on the stay instead.

Topeak classify the Redlite Aero as water resistant rather than fully waterproof. The clip-together design suggests you might be able to force some water in on a really filthy ride, but I've not had any water get in during testing. The way it's designed means the mounting strap pulls the light down onto its rubber foot, creating a tight seal.

Overall it's a very likeable light. The simple design makes it a breeze to fit, it's bright enough to be used on its own, and the versatile mount means you'll easily find a place for it somewhere on the back of your bike. And is it aero, like the name suggests? Well, yes, I guess, although if you're worried about how aero your rear light is then you probably want to take a look at yourself.

Looks like a great design, I mean that couldn't be easier to fit but I seriously don't consider the aero effects of my red light. I am glad they didn't jack the price way up just because it was labeled "aero"

Will it fit on 'aero' seatposts, such as the Giant vector?

Exactly, that's the point of it being called aero - not the light itself but will it go onto aero road bikes.

I have a lot of trouble getting lights onto my Ridley Noah.
