I have the red tail, 2 white Thunderbolts on each side of front fork and a 550 lumen Serfas headlight.
Thunderbolts are about $40 bucks each, comes with cord but not charger.
Great product.
I have a set of Thunderbolts and I love them but even these are only rated to last 1.5 hours if on steady:
Modes: 1.5 hours (high steady); 2.5 hours (low steady); 4 hours (high flash); 7.5 hours (low flash)
