🔧 Headlight Bulbs - Replacement

Assumption: This covers both front low-beam headlight bulbs. If you meant the high beams, the physical process is the same but the bulb type is different.

Replacing both headlight bulbs at the same time keeps light output even on both sides. On your Silverado, the headlamp assembly comes out first, then the bulb is swapped from the back of the housing.

Difficulty Level: Beginner | Estimated Time: 0.5-1 hour
