Knog’s … bright flashing LED’s … but only to be seen not to see with (ie urban lit roads only)… I am sure Strida UK will sort you out - I ahve always been very impressed with them … if anything they seem to under charge.
hi-visibility TL-60 triple LED rear light (replaces reflector on rear rack). Comes standard on STRIDA 5.0 - HK$140
It can also be installed on a Strida 3.x
