highway=traffic_signals means "this intersection is governed by traffic 
signals". If you want a tag for "there is a physical signal here", use a 
different one. Using highway=traffic_signals for this will lose 
important information about what intersections have signals (for 
example, a router can no longer say "turn left at the second signal").
