Replacing Dynamo

[irrational]

Hi all,

Could you please give me advice on how to replace bottle dynamo to a battery without changing the wires & lights?

To the frontlight there is only one wire going to the lamp through the frame tube. Don't know how to connect the +/- of the battery as there should be 2 wires.

Thanks & my apologies for a potentially stupid question.

Connect + to wire leading to light.

Connect - to bicycle frame. Make sure that there is sufficient electrical contact with the frame.
