This is a set of 4 billet polished
aluminum knobs including 3 Heater and A/C knobs and 1 headlight
They will fit 99-02 Chevy and GMC fullsize trucks including
the Silverado, Tahoe, Sierra, and Suburban.
These knobs have
a lighted indicator in them so that you can see your control
settings at night just like the factory knobs. Many other
aftermarket knobs do not have lighted indicators.
Very easy installation.
