Che io sappia l'illuminazione a LED fa abbastanza schifo.
In compenso i LED sono ottimi per
essere visibili, che è un'altra cosa.
EDIT: ho fatto qualche ricerca e al momento per le luci anabbaglianti non si usano principalmente per un problema di affidabilità in condizioni di surriscaldamento.

LED lighting systems are sensitive to heat. Due to the negative influences of heat on the stability of photometric performance and the light transmitting components, the importance of thermal design, stability tests, usage of low-UV-type LED modules and UV-resistance tests of internal materials has increased dramatically. For this reason, LED signal lamps must comply with the intensity requirements for the functions they produce after one minute and thirty minutes of operation. In addition, UN Regulation 112 contains a set of tests for LED modules including colour rendering, UV radiation, and temperature stability tests. According to UN Regulations 112 and 123, mechanical, electromechanical or other devices for headlamps must withstand endurance tests and function failure tests.

Su alcune auto di fascia molto alta però stanno sperimentando fari "all LED".
