Many of the smaller brush-motor controllers include a connector to power a brake light. For a 48V battery and 48V controller, I must assume that the output to the brake light is also 48V? I want to avoid having a 48V lamp. All other electrical accessories: headlights, taillights, horn, and 80A solenoid to connect the controller to the battery, are all 12V from a 48V to 12V DC/DC Converter.
Here's my question:
How can I power a 12V brake lamp from the 48V brake signal coming from the controller?
(1)Could I use a relay with a coil that could handle 48V? How hard would this be to find, and how much would it cost?
(2)Could I use another DC/DC Converter from 48V to 12V dedicated to just the brake light? I would need at least 25-30W, I think.
(3)Any other ways to do this?
I appreciate any ideas or comments.
