*Unless you have an upside down version of the Edelux II which uses a 3mm and 6mm ring terminal to connect to a rear light.
-Can Son Rear lights be vertically mounted?
No. The SON Rear Light has very wide but not very high beam angles. When mounted vertically this would be vice versa resulting in poor visibility from diagonal back.
Furthermore mounting in this manner would void its rating as a road-legal tail light, simply as the rating procedure was done in the horizontal position.
-How to connect a Rear Dynamo Light
NEVER connect ANY rear dynamo light directly to the dynamo hub, every dynamo rear light must connect first to a front headlight, as this acts as a voltage regulator. Failure to do this will result in your rear light blowing up!
-Connection to 5 Volt USB Power Supply:
All SON rear lights (Both AC Dynamo and DC E-Bike models) will work off a 5 Volt USB power supply, and will not harm the electronics. This means you can power these lights using a power bank, or integrate them into the Klite Lighting system.
NOTE:
SON rear lights for use with dynamos DO have a built-in capacitor that facilitates the stand light function, whereas the DC SON rear lights are designed for DC input only from an Ebike battery, as such do not have a stand light function as the battery provides continuous power to the front and rear lights.
