Vehicle HeadlightPractical lighting guidesVehicle Headlight is an independent editorial and utility project owned by Diogo Tibiriçá. It helps drivers understand common lighting questions and organize the information needed for the next step.
What we make
We publish research-based explainers and free browser-local tools. The guides focus on symptoms, source identification, lenses, moisture and maintenance. The tools help you build a workshop note or a replacement checklist.
What the work is based on
Technical explanations cite manufacturer or public-agency material and describe the source’s limits. The editorial desk is an institutional byline. We do not claim mechanic credentials, a repair shop, vehicle inspections, hands-on product testing or a verified vehicle-to-bulb database.
A new edition
This edition was created in November 2026. Some useful article addresses were retained from an earlier site; their current content is newly written. The site is not a restoration of the earlier software.
How to use it
Read the guide that matches your question, record observations from a safe place and use your vehicle’s documentation for specifications. A qualified repairer must assess faults that require testing.
