I love the synced vibration/beep feature on crossing buttons, as I made a habit of laying my hand on top of the thing while waiting for the light to change. It gets my attention much faster than hearing/seeing the signals change, since I'm usually looking around during the time I'm waiting. Mostly at the lights for cars, since that hints at when it's my turn to go. (I can see and hear just fine, accessibility features like this are just bonus for me.)

I am most used to these ones specifically: https://c8.alamy.com/comp/ECW0FA/pedestrian-crossing-traffic...

Can be activated with your elbow, the thing beeps and the bottom lights up when you activate it.
