[Closed] Laser rear lights which define a safe space around a rider

They work ok - I have one from Torchy via ebay BUT they EAT batteries and my first one failed after less then 2 weeks and one light rain shower.
In fairness - one email and a new one showed up the following day.

i have had one for months. got mine from dx before there uk sellets. I t has worked fine, onpy down side is batteries dont last as long as ya average rear light and its a jolly big unit

They're shit. A few club mates have them, nothing like as bright as they'd need to be to be visible
