I like Niterider lights but their mounts are crap.

I have a Bontrager Ion 800 that will light up the sky, but it's brand new because it's a warranty replacement for the Bontrager Ion 700 that broke on me, so the jury is still out.

When I'm really doing a lot of night riding I like 2 lights - one on my helmet and one on the bars. As a bonus, the helmet light lets me annoy bad drivers.

Tail lights -- For visibility, the Serfas USL-TL60 can be seen for over a mile away. I've literally had drivers pull up to tell me how far away they could see it. HOWEVER, I've gone through 3 of them -- there's some design flaw in the charging port and it eventually stops working.

The tried-and-true Cygolite Hotshot has been steady-eddie reliable for me.

I just bought a Bontrager Flare R (to replace the Serfas, which died on me). I bought it after a buddy of mine had his on daytime mode during a 10-hour gravel race and it lasted the entire race. So far so good.
