I run in the morning before work and the sun is coming up later and later everyday. I also run alongside a busy highway, even at 6 am for about 1 minute both ways. This highway and the rest of my run has no outside lights. This makes my runs very dangerous. I have purchased a light accessory for a running hat, but I feel like there isn't enough light. What are some really good running lights, both for me to see and for cars to see me? Please post links if possible. Thanks.
