Volkswagen Jetta Bulb Size By Years
Misconception: people often think bulb size charts are just a confusing catalog you can skim past. It seems true because many vehicles share similar bulbs, and the jargon looks interchangeable. Think of it as a mental model problem more than a technical one.
What is true is the list is meant to save you time and mistakes for your 2018 Volkswagen Jetta. The chart maps each lamp — low beam, high beam, turn signal, fog, brake, reverse — to the correct bulb type and wattage, and offers a rule of thumb for replacements and upgrades.
Implications are practical: matching the right size avoids fit and heating issues. Quick tests: compare the chart entry to your owner’s manual and the bulb itself, and check fit before purchase.
