Are there any tools available which allow you to display nodes on a map based on what tags they have? For instance, if I wanted to see all the nodes on a map with "traffic_signals=*", say a dynamic version of this map that I could zoom in and out of:

Answering my own question and as per scai's comment above, I have used overpass-turbo.eu ...it works a treat
