+1, this really is the best option out there. don't waste your time or money with 1w, 5w, platic led lights or that 40lumen blackburn flea things. q5 are throw lights which means they can be seen from far away. its a great blinkie, a since battery last about 3hours flashing. even on soild it does a decent job, not as nice as a p7 for flood, but decent all the same. built quality is good, never flickers with lose battery connection and hasn't broken down yet. really you can't go wrong a with this q5 light
