Just picked up this strobe from Firehouse Technologies. I made the mistake of looking at it and have been seeing spots for an hour. Has different modes for your liking. Its advertised as 800 Lumens I believe. As I get older I find myself squinting when the car is further away so I figured I’d give this a shot. It’s meant for drones and can be seen like 3 miles away or some crap like that. I highly recommend it.
