Driving lights or spots. For example something that gives a better-than-low-beams pattern in fog or driving snow, without giving you that Star Trek warp drive feeling.
Not saying you need them, it was merely my pre-coffee association chain working overtime.
You spoke of getting rails done, and it's dirt common to use the rail anchor as mounting point for LED support brackets. The hard part to LED bars, of course, is doing the electrical switch panel in the cabin and the breakout under the hood - but having those would enable biggie driving lights mounted low down.
The side rails I mentioned are the roof rack side rails, not down below. You can't see it in this picture but I do have LED fog lamps and my headlights are LED with adaptive lighting technology.
