Does Chevrolet Blazer have projector lights or reflector lights?

Chevrolet is known for innovation. Chevrolet has blessed the market with numerous outstanding vehicles in all these years, and Chevrolet Blazer is a prime example.

We know different vehicles and models have different headlight configurations. So, what sort of headlight does the Chevrolet blazer has?

The earlier models of Chevy Blazer were equipped with sealed beam halogen headlights (reflectors). These are the headlights you see in most old vehicles, and they are called sealed beams because the bulb and assembly should be one-piece and hermetically sealed. If the bulb stops working, you will have to replace the whole assembly.

Later models from the late 90s to 2005 had composite halogen headlights. In composite headlights, you can change the bulb if it gets burned.
