While stylish, these designs suffered from slight non-uniformity, stray light, high cost, high weight, and lower brightness. It was also difficult to resolve multiple elements from a distance if the design elements were too close to each other in proximity. To this date, new vehicles are still being introduced that have inhomogeneous taillight and DRL functions.
Elite taillight
These back-lit architectures create bright elements but are very pixelated. US (Chrysler, Ford) and Korean (Kia) OEMs also took this back-lit approach with their night-time design elements but incorporated diffusion to get a homogenous look.
Dodge Durango taillight
Such designs had many advantages: they were lower in cost, provided more design freedom, and reduced the number of required LEDs. German OEMs like Audi took note and started to use the same approach in the front and back of their vehicles.
In their newly re-designed 3 Series line up for 2019, BMW is now using this back-lit diffused approach in their tail function.
