Yes crazy but fantastic - you will wonder how you managed without it! This Toilet Light easily attaches to any toilet and uses an inbuilt PIR sensor which turns on as you approach illuminating the toilet. Additionally the Lav Nav Loo Light has red and green lights to indicate if the seat is up or down. With the Lav Nav fitted you no longer need to turn on the main, sometimes dazzling light; the Loo Light will illuminate the loo and its surroundings. Practical for the home and probably the most unique present in the world!
