You will NEVER get any kind of consensus here because some people think there's no such thing as bright enough unless you're lighting shrubs on fire as you ride by, and others are afraid of offending light sensitive vampires on the MUP.
I have 2 tail lights - one for each bicycle.
I also have 2 front lights - same.
No regrets.
CatEye rear light - any that has at least 3 LEDs in it. Most are rain (and downpoor) resistant.
Front light - on one bicycle I use a flashlight, on a flashlight mount placed on handlebars. Good light, rechargeable AA batteries. On the other, a dedicated bicycle LED battery light.
