Nothing special, bought on Amazon. Idea is when we ride as a group all riders use red lights to show the next rider is coming and the last rider has green lights on to show he is last in the group.
We get snow again. Be good to get a few cold nights before it comes back. Give me some minus 20C weather and freeze everything solid so we can last until March. Should be some frost where trail is hopefully. Be like last year so can go quick when it warms up with no frost. I couldn't believe how fast it went last year, but thankfully not much sun at moment to sped up snow loss. Time on our side this time.
