Lighting is central to Diwali celebrations. Traditional diyas are often used to symbolize light overcoming darkness, but flameless candles and electric lights are safer alternatives, especially in homes with children or pets. When using candles, ensure they are placed at least one foot away from flammable materials and never leave them unattended. For electric lights, inspect cords and plugs for damage and follow manufacturer guidelines for indoor or outdoor use. Layer lighting to create a warm and inviting atmosphere, with focal points at entrances and softer lighting in gathering areas.
