Reflex TL-570 Auto rear light
This unusual light has a large reﬂector, one high power LED and ﬁve smaller LEDs. The ‘auto’ in the name refers to the automatic activation of the light when it senses both movement and darkness.
It’s very sensitive and will remain on for 50 seconds once motionless. It has ﬁve modes, including our particular favourite, which we’ve named ‘disco’. A front version costs £30.
