The newly unveiled seventh-generation BMW 7 Series flagship saloon has rolled out under what BMW itself calls the “biggest facelift of all time,” and tucked in among the headline-grabbing engine refinements, redesigned cabin and overhauled bodywork sits another talking point: the illuminated grille. The luxury limousine joins the 5 Series and Bimmer’s family of X SUVs in adopting BMW’s so-called Iconic Glow treatment, lighting up those famous kidney apertures with a halo of LEDs and fibre optic strands. The decision feels right at home on a saloon already steeped in Neue Klasse design language and a nameplate famous for rewriting design conventions, the controversial Bangle Butt era being a prime example.
The illuminated grille might feel like a fresh styling tic, but its roots stretch back further than many enthusiasts realise. While the 2021 BMW XM Concept is widely cited as the production-bound starting point for Iconic Glow, the idea actually appeared on the X6 two years earlier as a clever party-piece tied to the driver’s door opening. Mercedes-Benz dabbled with light-up three-pointed stars on its higher trims long before that, while Chrysler experimented with backlit grille treatments back in the 1960s with the 300L. Even Mercury beat everyone to the punch, fielding a split illuminated grille on the 1986 Sable saloon and a full-width version by 1989, a signature look the American brand maintained until 1996.
Plenty of practical justifications support the design beyond pure visual drama. LED bulbs around the grille throw additional ambient light forward, which proves genuinely useful for oncoming traffic and unsighted pedestrians during low-visibility conditions, particularly relevant amid growing complaints about overly aggressive headlamp glare. Brand recognition is another quiet strength, because illuminated kidneys could mark out a BMW from a hundred metres away in much the same fashion that Falcon doors instantly identify a Tesla Model X, or Rivian’s distinctive light bar signals its presence. Mercedes has rolled out pixel-style grille tech across its EQ range, while Cadillac has applied a more restrained version to the Lyriq SUV, suggesting the segment is heating up rather than cooling off.
Naturally, illuminated grille hardware brings drawbacks worth weighing. Iconic Glow is rarely a standard feature, sitting on the BMW options list and tacking meaningful sums onto the build sheet, with M-division variants commanding the steepest premiums. Retrofitting older models can climb into genuinely eye-watering territory, while the Mercedes GLC’s 942-LED animated panel demands its own outlay. Aesthetic objections are equally vocal, with critics branding lit-up grilles undignified, gaudy or simply destined to age poorly, especially given BMW’s already polarising radiator apertures since the second-generation 4 Series Coupe debuted. There’s also the engineering reality that adding fibre optics, microcontrollers and bespoke wiring creates fresh failure points, whether through software gremlins requiring over-the-air fixes or stone-chip damage incurred during everyday motoring.
Despite the doubters, the illuminated grille looks set to spread further rather than fade. Electric models lacking conventional radiator openings have given designers a blank canvas to play with, and ICE vehicles are picking up the trend as a modern flourish. The Automotive Illuminated Grille Panel Market was reportedly valued at $935.9 million in 2024, with projections suggesting it could swell to $2.5 billion by 2035. With major suppliers including Mitsubishi Electric, Valeo, Magna International, and Entheos investing heavily, alongside countless aftermarket specialists, walking away from that growth curve would be commercially baffling. Buyers eyeing the new 7 Series, therefore, need to decide whether glowing kidneys feel like a future-proof signature or simply expensive kerbside theatre.
