A mirror that ﬁts onto the end of your bars with a white LED light at the front and a red LED at the rear is a great idea.
Add to that a ﬂashing yellow indicator with audible beep activated by a simple switch at the end of your bars and the Winkku turns into something much better.
The mirror is especially useful if you do lots of riding in trafﬁc, and the lighting, indicator and ﬁttings are great. It’s easy to ﬁt, easy to use, and can be quickly folded back for nipping down lines of trafﬁc.
It’s available in left or right-hand versions, with ﬁttings for straight or drop bars, and it runs on three AA batteries.
