Using this rangehood halogen light assembly is easy. First, make sure your rangehood is turned off and unplugged. Then, carefully remove the old light assembly if there is one. Take the new light assembly and connect the 2 - pin female connector to the corresponding male connector in your rangehood. The 15cm flylead gives you enough flexibility for installation. Once connected, you can insert the assembly into the designated space in your rangehood. When it comes to the halogen globe, it will provide bright light for your rangehood. Just be careful when handling the globe as it can get hot during use. As for maintenance, it's a good idea to clean the light assembly regularly. You can use a soft, dry cloth to wipe off any dust or grease. If the globe burns out, simply replace it with a new 12 - volt, 20 - watt halogen globe. Always remember to turn off the power before performing any maintenance tasks to ensure your safety.
