Hello. I read the "Light Selection Guide" but I'm still unsure of what I should get. I sometimes need to ride at night and would like something to see the path better. I mostly ride on sidewalks, so I don't really need to be seen. I really need it for when I am around the residential area where I live. I've ridden many times without any lights, so it's not like it is complete darkness. I think an HID is too much. I was guessing a Halogen, somewhere between 5 and 15 watts. Could I use an LED light? Thanks
