Rigid lights are super high quality. The pros: less current draw to power them, much less, putting less of a strain on the charging system and battery, and won't make the can bus shut anything down from drawing too much current. They last practically forever compared to a halogen or HID light. They are available in spot or flood pattern, and amber or white colors.
The cons: Some of the bigger light bars are super expensive, like the 20" and 50". They may not be as bright or have the output of HID offroad lights, but IMHO that makes a set of Rigid Duallys great for back up lights and/or fog lights.
I have a set of Rigid Dually D2s to use as back up lights on the rear cross member I still need to install once I get the corner armor and tire carrier installed, and plan to wire them into the factory wire harness.
