2019 Volkswagen Jetta Bulb Size

Decision: Provide a concise bulb size chart for the 2019 Volkswagen Jetta to help a skeptical evaluator identify correct lamp types quickly, reducing guesswork and returns. Constraints include trim variations and aftermarket labeling, so the list focuses on commonly used OEM sizes and notes possible exceptions. Options are presented as a simple comparison of headlight, fog, brake, and interior bulb types with socket designations and wattage ranges, supported by direct inspection and manufacturer references. Evidence and limitations are flagged where a trim or optional package may change the specification, and the interpretation leans toward conservative selection to avoid electrical issues. Recommendation: Use the chart as a starting point, verify with your owner's manual or VIN parts lookup before purchase, and consider professional fitting for headlight alignment. Risks include mismatched sockets, heat damage, or voided warranties if aftermarket bulbs are inappropriate.
