The Trace 4 delivers a scarcely believable 360 lumens from a 38g package, which makes it the easiest light in your life to actually remember. It lives in a jersey pocket, a rucksack lid, a saddlebag or clipped to the bars all week. USB-C charges it fully in 90 minutes. A tough CNC-machined aluminium body and an IP67 rating mean British wi

This is my third set of these wonderful little Exposure lights - I still use my >10 year old Flash/Flare set on occasion and wanted a new set to replace my not quite as elderly original Trace/Tracer with a micro USB socket. Everything else I use now has type C, so I managed to self-justify the upgrade.
Still the same tiny size, epic build quality, simplicity of use (just set and forget) and ridiculous burn times from something so small. And they all fit in the same mounts, so dead easy to move about.
One on the bar and the other on the back of my helmet every time I hit the road and/or gravel trails.
They are just a normal part of my kit in the same way my helmet and gloves are. Never leave home without them! Now I don't actually have to keep swapping them bewtween bikes either.
Daybright pattern does exactly what it says on the tin - it gets you noticed from a very long way off regardless of the lighting conditions. Rather important if you dont want squished.
Flawless performance from all 3 sets and superb customer service should you ever need it (which only happened once when I managed to crack a Flash hood after a stack and they sent me two spare ones foc).
Love these lights and have never needed any of their bigger siblings yet.
They do appear expensive against some of the opposition but I believe you are getting the best value for money in the long run . They just keep working.
And they are a UK company...

Absolutely great little lights. I got them purely for being seen as the nights get longer and the days shorter. I must admit the one button UI is a bit weird, but it works.

Upgraded from the older mini USB style units to the “C”. Hoping for more battery life and the braking feature sounds good.
I wear them on top of my helmet with the Exposure light helmet mount. Ultimate car visibility. You can point the front white one right at drivers in intersections to make sure they see you.
I think all the Exposure lights are awesome.
I have a Strada SB with activ for my E-bike .
A Joystick 18 in purple for my Cervelo Aspero 5 in Sunset Purple.
Works great for the tunnels on the Palouse to Cascades trail and if I get caught out too late in the winter here in the Pacific Northwest.
