For a light with LED components, what percentage of LEDs must be functioning to pass inspection?

In Maine, for a light with LED components to pass inspection, it is required that 50% or more of the LEDs must be functioning properly. This requirement is established to ensure that vehicles maintain a minimum level of visibility and safety on the road.

When considering the functioning LED components, having at least half operational ensures that the light source is adequate for signaling and visibility purposes, significantly reducing the risk of accidents. This standard recognizes the unique characteristics of LED lights, which can often be very efficient and bright even with some LEDs non-functional, but still aims to uphold safety regulations by requiring a majority to be operational.

In contrast, lower percentages would not provide sufficient assurance that the lights are effective and visible, which could compromise safety.
