Serfas TSL-T1000 Bike Headlight Combo w/Tail Light
I bought this light after reading the great review gave it in the 2015 bike light shootout. Their testing proved that it pumps out MORE than the rated 1000 lumens @1130L! The beam pattern is really wide and lights up the trail very well. The tail light that is built into the battery pack is pretty bright too. I even had a rider on the trail comment that he could see the combination of the head and tail light long before he saw me, which is nice when riding in the trees at night. I use it as my helmet light and really like how low profile the light is. It comes with a nice case, a charger, handlebar and helmet mounts. One of the cooler features is the nice little 'optional' remote control switch. You can mount it to the bars or your helmet, and you dont have to touch the button on the light! This is a killer light at a great price.)
