Hyundai Mobis new tail lamp uses one LED to perform two functions

Date:22 February 2021

Hyundai Mobis has unveiled its latest creation, a new type of LED called the HLED that can be bent as a thin film. This new design and technology mean a single LED can serve as both the stop lamp and the tail lamp at the same time with only 5.5mm thickness of the LED surface.

Most vehicles today have the tail lamp and stop lamp separately under the safety laws. According to the laws, the stop lamp must be much brighter than the tail lamp. However, the new HLED allows the tail lamp and the stop lamp to be implemented with a single LED by just controlling the light with electrical signals.

Moreover, the HLED can generate a bright and uniform stoplight even when it is bent by emitting light in five different directions. As a result, the rear lamp will be more visible to the drivers of the vehicles approaching from the rear and side.

Compared to the existing ream lamp, HLED can create various lamp designs since it can be bent or curved. It is also possible to secure more space and offer lower weight, as it removes all the internal components used for the existing rear lamp by controlling light with the new LED alone.


“We will accelerate technology development and introduce the lamp technology customized for future automobiles as represented by electrification and autonomous driving.”, said Oh Heung-sup, the head of the Lamp BU at Hyundai Mobis.
