An HGV lamp holder typically refers to a type of lamp holder used in Heavy Goods Vehicles (HGVs) or commercial vehicles. These lamp holders are designed to securely hold lights or bulbs, especially in environments where the vehicle is subjected to rough conditions, such as vibrations, weather changes, and other physical stresses.

HGVs often require durable and robust lighting solutions for various purposes, including:

1. Vehicle exterior lights (e.g., brake lights, tail lights, indicator lights)
2. Interior lighting (e.g., cabin lights, dashboard lighting)
3. Work lights or auxiliary lights for night operations or when parking.
