European Union (EU) organization states car LED lights have no direct risk on human health

The European Union Scientific Committee on Health, Environment and Emerging Risks published research stating that there is no danger for healthy humans to be using to car LED lights in the normal use of lighting during drive.

Of course, there has been a long debate in the LED lighting forum as to whether the short-wavelength blue energy peak associated with most phosphor-converted white LEDs can cause a risk to the human eye as automotive LED lights takes the place of the traditional halogen lighting market. The US Department of Energy (DOE) has expressed the similar opinion several times. 

The EU had requested SCHEER with studying the subject carefully with the specific direction to evaluate the influence of blue energy on human eyes and skin. The committee concluded that typical human exposure to such blue energy from car led lights is far lower than exposure safety limits that have been previously made. And the report said the lack of ultraviolet (UV) light in LED lights  may reduce the risk humans face from UV in other light sources including the Sun.

Clearly, the report is in draft stage, and the report does warn of potential issues with LED lights including discomfort and disability glare associated with LED lighting implementations in auto LED headlamps,LED driving lights and other applications. Those issues are just present in LED lights. The report also mentions glare related to street LED lighting but says that glare has been a problem primarily where lighting design and LED chip selection has more priority on energy efficiency over quality. In any case, the glare issue is said to have a temporary and not permanent risk on healthy humans.
