Blackburn 2'Fer on the rear of the helmet.
Yup, Planet Bike Rear Rack Blinky 5 on the rack.
Just over 100 meters/335 feet from camera to the far turn at the end of the block. About 20 feet from the camera on the near turns. I used a 35mm (equivalent) moderate wide angle for a relatively normal perspective approximating our vision (40-42mm would be closer to how we see things, not counting peripheral vision).
I thought about ordering the Serfas TL-STP, but it would have taken a week. The Planet Bike was available for same-day delivery via Amazon. It seems adequate as a nighttime taillight. The Bontrager Flare R appears to be brighter for day/night use, but twice the price.
I'm wondering about modifying something like the Serfas SL-255 headlight with a red filter/diffuser. It uses a pair of AA batteries, lasts a long time per set, probably bright enough to compensate from light loss through a red filter. Not sure it's worth the trouble, though, with the Flare R and Serfas Thunderbolt already available.
