Question:

Dear Sir or Madam, Do you offer a 12V battery and if possible wiring connectors which i can connect the trailer wiring light kit so instead of having to run that black power cable underneath the entire car up to the front 12V main battery? I only tow for a short distance and short time so the limited battery life would not be a factor. thanks! Erik

Hey Erik, unofficially I have a solution for that with the Bright Way Trailer Breakaway kit part # 3802336. This is a pretty small battery in a box you could run your converter box to instead of all the way up to the vehicle battery but I have to emphasize this is not recommended and you'd run chance of killing the battery and not having trailer taillights.
