When the sun begins to set I use a front 80 lumen ( white ) blinkie on the bars and turn my helmet torch on to flash when approaching traffic lights. Now you would think this would be enough but no matter what you use to get seen you still have to ride defensively. Just the other day ( at sunset ) I was approaching a red traffic light and turned the torch strobe on ( making two blinking white lights, bars and helmet ) . Just before I reached the white line the light changed and I had the green to go. When I started to go straight through the light some car tried to make a left in front of me. Even with a bright bar blinkie and super bright torch strobe going some fool threatened to hit me. Of course I saw what was happening ( as did the driver ) and both of us stopped. Thankfully no one was hurt but I was ticked that the guy didn't see a bike with flashers going waiting for the light. Some people are in such a hurry all the time that they habitually gamble when making turns. I guess I could say that at least I did get seen but getting seen sooner is always better than getting seen later.
