They have amber running lights that face forward, red arrow lights in the mirrors, and the two little lights that point towards the rear when cargo light is on.
Hello
I have a 2018 2500HD Duramax, with dual arm, extendable, power towing mirrors. The mirrors have turn signals. I would like to upgrade to the power folding mirrors with puddle lights. How can I get the harnesses needed? And confirm the additional parts needed.
Many thanks
