dobbelfilamentpærer
Dobbelfilamentpærer, also known as dual-filament bulbs, are a type of incandescent light bulb that contains two separate filaments within a single glass envelope. Each filament is designed to produce light at a different wattage or brightness level. This allows for two distinct light outputs from a single bulb, often offering a low-intensity and a high-intensity option.
The primary application for dobbelfilamentpærer is in automotive lighting, particularly for taillights, brake lights, and turn
The construction typically involves two tungsten filaments, each connected to separate electrical contacts on the bulb
