Xenarc HID (high-intensity-discharge) sealed-beam headlamp kits from Osram Sylvania's Automotive Lighting Division offer direct replacements for a heavy-duty vehicle's standard sealed-beam lamps — large and small, round and rectangular — in both two- and four-lamp systems. They produce a more intense, high-color temperature (white) light, and provide three times the light output and nearly 10 times the service life of standard halogen headlamps. Xenarc HID auxiliary low-beam lamp kits are also available.
