I have two MiNewts on my recumbent tadpole trike and a Dinotte 200L on my Trek hybrid. All three lights have different levels of brightness on steady mode, plus a flashing mode. The Dinotte has several flashing modes. I like the Dinotte because you can use 4 AA batteries. I use Sanyo Eneloop NiMH rechargeables. They are about the best rechargeable AA available.
