My PIP(plug-in Prius) has the Advanced Package with great dual-beam LED headlights. When Ovwrlanding, even when using the high beams, I needed more light.
The goal was accomplished to have a light bar attached to my Thule roof rack with a Rhino Rack 43174 VA and HD LED Light Bracket.

Next will be two small cubes on either side of the car attached to the roof rack facing backward.

The light bar is wired to the second button on the dual switch I installed to control my DRL. :)
