Frequently Asked Questions
Will this 2003 Silverado headlight fit my 2005 GMC Sierra?
Yes, this headlamp assembly uses interchange 878A and fits 2003-2006 Chevrolet Silverado and GMC Sierra 1500/2500/3500 models. The GMT800 platform used the same headlight design across these model years.
Is this a complete headlamp assembly or just the lens?
This is a complete OEM headlamp assembly including the housing, lens, reflector, and all mounting hardware. You’ll need to transfer your existing bulbs or install new ones.
What’s the difference between Grade A and lower grade headlights?
Grade A headlights have clear lenses with minimal wear, intact reflectors, and solid mounting points. Lower grades may have lens clouding, minor cracks, or worn reflective surfaces that can reduce light output.
Do I need to aim the headlight after installation?
Yes, headlight aiming should always be checked and adjusted after installation to ensure proper beam pattern and avoid blinding oncoming drivers. Most auto shops can perform this service quickly and inexpensively.
Will this work with HID or LED conversion kits?
This OEM halogen headlight housing can typically accommodate aftermarket HID or LED conversion kits, though you may need additional mounting hardware or adapters depending on the specific kit used.
How can I tell if I need the left or right side headlight?
This is the left side (driver side) headlight. Vehicle sides are determined from the perspective of sitting in the driver’s seat – left side is the driver side, right side is the passenger side.
