The Philips D5S Xenon HID (high intensity discharge) bulb from Lumileds is available as an aftermarket replacement.
The bulb is standard on all factory-HID equipped 2016 and 2017 Chevy and GMC full size pickups and SUVs as well as other makes.
Delivering a bright white 4500K light temperature and a wide and homogenous beam, this innovative bulb design integrates the electronic high voltage starter and ballast into the lamp base. It also does not contain any mercury.
Lumileds Holding B.V., a subsidiary of Royal Philips, is the manufacturer and sole supplier.
