Technically, Big Ben is the name given to the massive bell inside the clock tower, which weighs more than 13 tons (13,760 kg). The clock tower looks spectacular at night when the four clock faces are illuminated.

Yes, Big Ben (the Elizabeth Tower) is brilliantly lit up every night in 2026. Following the massive multi-year restoration project that was completed in late 2022, the lighting system was completely modernized with energy-efficient LED bulbs. These lights are designed to mimic the original Victorian "gaslight" glow while allowing for more dynamic displays. The four clock faces are illuminated from within, and the exterior of the tower is bathed in a warm white light that highlights the intricate stonework and the "Prussian Blue" details on the clock hands. On special occasions, such as New Year's Eve or national anniversaries, the tower can be lit in different colors or serve as a backdrop for light shows. The "Ayreton Light," which is a small lantern located at the very top of the tower, also shines whenever the British Parliament is sitting after dark, serving as a traditional signal to the people of London that their representatives are at work.
