Part Description
This left hand headlamp assembly was removed from a 2010 Cadillac CTS donor vehicle. The halogen headlight unit is designed for non-V-Series CTS models and has been thoroughly inspected by our parts specialists. This OEM headlamp is currently on our shelf and ready for immediate shipment.
Headlamp assemblies commonly need replacement due to accident damage, lens clouding from UV exposure, or internal component failure. The CTS headlamp houses the low beam, high beam, and turn signal bulbs, along with the reflector housing that directs light output. A functioning headlamp assembly is essential for safe nighttime driving and legal vehicle operation.

Is this a halogen or HID headlight assembly?
This is a halogen headlight assembly. It uses standard halogen bulbs for low beam, high beam, and turn signal functions.
Does this headlamp come with bulbs installed?
The assembly includes the housing and sockets, but bulbs may need to be transferred from your old unit or purchased separately depending on condition.
How do I know if I need the left or right headlamp?

Can I upgrade this halogen headlamp to HID?
