Followed this thread closely as was also in the market for small inexpensive commuting lights.

Ordered Trace and TraceR as a package off Tweeks yesterday, £75, on the free 48 hours delivery service. It arrived today.

Lovely design, simple, light and bright looks built to last. Just what I was after.

So thanks folks, I’m dead happy with them!

I’ve been through what feels like dozens of rear lights.

Then I got an exposure tracer and all my problems were solved. No point even thinking about anything else in my view. On a saddle mount on my road bike, its virtually invisible from the side, on the bottom of seat post on mtb, out of the way of the dropper.
