Aqua Signal LED Chart lite, Red Wire Marked Negative..?

Quick question, we are installing an aqua signal Chart light. There are two wires, black and red. The red wire is marked, along the length of the wire with dashes.

This is a negative wire correct? A red negative wire?

Is there a way to check the light ( with no power running to it) what is pos and neg with multimeter?

Sorry if this is silly question

If you hook it up Wrong it just won't light up. No harm done, as it is a diode.
Switch wires if it doesn't light up. Diodes only pass current in one direction.

Thanks, we were sitting here talking about the diode, just couldn't make up our minds if it would fry or not.

The red will be + ignore the dashes.

Red was positive. Strange they'd have what clearly looks like a negative symbol on the positive wire.
Thanks for the help. As usual, you all are great!
