if you want to ride night rides not what you are looking for. The tail light has very short life and makes for a stressful ride as you dont know when it will go off. The front light is good and gets the job done but the options are limited.
So, i have been going to a mart every few months to get new lights. I thought those were bright. Now, this combo is super bright. Even the lowest setting is much brighter. And the bonus is, it's rechargeable.
To see, and be seen!
