Hyundai Sonata Bulb Size By Years
Decision: This page provides a concise bulb size chart intended to help a 2003 Hyundai Sonata owner identify compatible lamps quickly, reducing guesswork and shopping time. Constraints include model-year variations and trim differences that create potential ambiguity, so the list emphasizes common circuit functions rather than every obscure variant.
Options: the chart compares typical lamp locations — headlights, fog lights, turn signals, brake/taillights, and interior bulbs — and gives common size candidates and replacement tips. The comparison highlights trade-offs between standard halogen fits and available LED or xenon upgrades, with evidence noted for fitment and electrical considerations and limitations acknowledged where factory options diverge.
Recommendation and risks: use the chart as an initial reference, confirm fitment against your vehicle’s manual, and follow safe installation practices.
