The LEDs are pretty bright. As far as the night driving, haven't done too much actually to be honest but I have no doubt there bright enough. I have my lights all on my running battery which is a 3s lipo 4000mah and have great driving time. The LEDs have such a low draw on battery that I don't notice it effecting my run times. Just make sure u properly resist them per your application, they only have like a 3v-5v max.
