The most common Ice Detection Probe (the vibration type as described above) is made by Rosemount (now Goodrich). It's fitted to all Bombardier aircraft - probably as they're designed to Canadian regs.
Most other aircraft (including the ones with the probes) have wing inspection lights that illuminate the leading edge and are aimed at a part of the airframe susceptible to icing that is painted black so ice shows up. On aircraft with winglets, this is often at the angle between the wing & the vertical winglet.
