A
distinctive feature of BMWs are their Illuminated
headlamp halo rings. More recently, with the increased
use of HID lighting, these rings appear almost yellow
in comparison with the crisp blue/white light emitted
by HID units. This yellowness is particularly noticeable on lighter-coloured vehicles, with the latest craze of candy-white BMW's being testament to this. This disparity can really detract from an otherwise beautiful-looking vehicle's appearance.
To enhance appearance, PIAA has developed
a range of upgrade kits which increase the brightness
of the halo rings. These simply plug into existing
headlamps in place of standard filament bulb-based items to give the vehicle’s headlamp Halo Ring
a clean, white 6500 Kelvin
