my favorite light is this
Serfas Spectra 150 Bicycle Taillight - TST-150
it has great battery life and bright well made, not sure if they are still available but this light is well made and durable, I have thousands of miles on it. I just replaced it with the Garmin rtl 515 radar / light and love the thing. I really rely on it more than I thought I would. the Garmin is pricey which is why it took me so long to get it but now I recommend it highly,
