The Supernova StarStream is a top - notch lighting system designed specifically for the Orbea Diem. It offers both high beam only and high/low beam options. This is a light - only setup. Each Diem comes equipped with a high - tech built - in lighting system that turns on automatically, ensuring your safety and illuminating the path ahead. The wrap - around lights enhance your visibility 24/7, making you visible from all angles, even from the side.

Using the Supernova StarStream for your Orbea Diem is a breeze. Just ride your bike, and the light will turn on automatically. You can choose between the high beam only or switch between high and low beams as needed. When riding at night or in low - light conditions, the high beam will give you a better view of the road ahead. During the day or in well - lit areas, the low beam is sufficient and can save power. As for maintenance, keep the light clean. You can use a soft, dry cloth to wipe it down regularly. Avoid using harsh chemicals or abrasive materials as they may damage the light. If you notice any issues with the light not turning on or changing modes, check the connections to make sure they are secure.
