I use daytime running lights when I ride, but you don't need, and I don't use 1,000 lumen light, during the day all I use is a 400 lumen headlight on strobe mode, and a 300 lumen tail light on daytime flash mode. At night I will run with two headlights, the 400 one on strobe mounted to my helmet, and a bar headlight using 700 lumens, which can go up to 1,200 but I rarely need that much light; then in the rear I put the 300 lumen light on steady high, and add another one to my helmet and that one runs on alternation flash mode at around 150 lumens.
You're not ever going to be going as fast as car down a highway, so you don't need anything real bright, 700 lumens is plenty up front unless it's a dark raining night out in the country then you might need 1,000 to 1,200 lumens.
I know a lot of people are going to sneer at me for saying that, and that's fine, I'm not going to debate you about it, if you feel safe running 25,000 lumen light on your bicycle, hey, whatever floats your boat. But remember, the brighter the light the less your night vision in your peripheral will be.
