In the past several years MoT has embarked on two programs to enhance traffic signal visibility. The first was a change from the old incandescent light bulbs to the new brighter (but power-saving) light emitting diode (LED) replacement displays in the signal heads. The second program was to enhance traffic signal head backboards with a border of highly reflective yellow reflective strip that greatly improves the visibility of the signal head. This has shown to be an effective means to improve safety at signalized intersections.
