GMC Sierra 2500HD Bulb Size By Years

Misconception: people often think a single bulb size list is enough for any car, so you might grab the first match you find. Why it seems true: many bulbs look similar and parts charts can be full of codes, so it feels like they’re interchangeable. Think of it as a mental model that hides small but important differences. What is true: for a 2016 GMC Sierra 2500 HD, bulb sizes vary by function and trim, and the right fit affects brightness, beam pattern, and connector type. The rule of thumb is to check both the chart and the physical socket before buying. Implications and quick recap: this list helps you confirm sizes quickly and avoid returns. A quick test is to compare the chart entry to the bulb in your truck and the connector shape.
