[RFI] LED streetlight noise.

[David Robbins]

how do you know they are pulsed?  and is it intentional or just the result of poor filtering?

most likely problem i would suspect are the likely use of cheap switching power supplies driving long wires way above ground... sounds like a good noise transmitter to me.

I've noticed excessive RFI coming from LED traffic lights ...
the red/yellow/green type....

wonder if the rfi noise is enough to mess with data on public service 
vehicles..
cops & firetrucks...ambulances...
too bad they find it necessary to pulse them for brighter output.....
