I'm an avid cyclist, but not only do I have front and rear lights, my entire bike is lit up with bright lights. I get angry myself when cyclists ride at night with no lights. I've nearly collided with them while driving AND while riding my bike at night. 

Many of them are young/college students or transients. The EPD really does need to set aside some resources in the fall for educating/citing cyclists. They can hang out on W 12th and won't find any shortage of them as they ride by. 

On a side note, I urge drivers to install a dash cam, as I have, to protect yourself in cases like this and really, any traffic accident.
