Question Concerning Rear Turn Signals and Brake Lights

Simple? I don't know why you think that......you have to add more bulbs and lenses, and move the wire from the stop lights into the turn signals. If you ever want to pull a trailer MOST trailers ---at least here in the states---are set up for the original style integrated stop / tail.

Anyhow, if you really want to do that, moving the stop light wire is what you do.
