Night-Light Safety Checklist: What to Verify Before You Buy
Safety is not a badge on a listing. Verify the exact model, label, power system, recall history, installation, heat behavior, battery access, seller, and warnings.

Verification checklist
- Verify the exact model, power requirements, intended location, warnings, and current seller.
- Treat certification as claimed until the exact product record is matched with the issuing body.
- Search the CPSC recall database and record the date; a no-match result is not a safety guarantee.
- Stop use if the product becomes unusually hot, damaged, discolored, loose, or electrically unstable.
