Sloat Ave in San Francisco installed new cross-walk lights after a student was killed.

However, the lights themselves are ridiculous and will probably get someone killed as well. I've never seen something like this before. Normally, crosswalk lights are yellow, and they flash yellow when someone is crossing the road. Other times I've seen flashing lights on the crosswalk itself to show that someone is crossing. These are great.

The ones installed on Sloat are flashing red lights, but they don't look like a traffic signal. I don't know why they chose this, but it's very confusing and I don't know what a flashing red light means in a non-traffic light context. It's stupid and overengineered, and they should have stuck with something much more conventional, like flashing yellow lights.
