>>1438546Depends on where you want to ride and how fast you want to go.
>>1437262 is a Light and Motion Urban 500 which I find good enough for trail riding, (I don't even use full power all that much except when there's glare from city lights, but I also don't ride super fast at night because I like to savor the atmosphere ) and a cheapish Planet Bike 2W LED light that takes AA batteries. The PB on its own is good enough for paved streets & for not blinding people on the bike path.
