These were trialled at some sites in Enfield, but were a nightmare. They are basically a vehicle horn glued to a black wait panel inside a PBU. The partially sighted hold their hand against the panel and it vibrates when at green man. These were mounted (if I remember) above the PBU. The vibrators vibrated too much and kept breaking the bond to the panel itself. We tried various glues, compounds and industrial sealants to bond them but it never worked sufficiently to make the trial viable. I'm not sure who the manufacturer was, or if they're still made but TfL may have some detail.

I have a vague memory that in the early days of Puffin crossing these were trailed but I haven't heard of their use since. Can anyone shed any light on current providers please ?
