I once had every single vehicle outfitted with aux. lighting before the era of bi-xenon and LED factory lights - with my favorite lamp being the PIAA 80 Pro XT driving light. Compact, with a base that was at the back of the lamp (as opposed to a Hella 4000, which requires a lot of depth since the base mounts at the front). They are NLA, but if you can find a set, grab them.
Having said that, my most recent experience with aux lighting came from the installation of a Rugged Ridge LED light bar. They make a wide range of quality (light quantity?) lamps in varying sizes. Mine was flat and expensive, for sure ($600+), but provided enough light to see directly ahead and 15 degrees off to the side for literally miles... low draw, too. As I don't run older Land Rovers in the winter (Vermont salt), mine are all now bare front - rarely am out out past dusk in the summer months to justify. I liked how low profile it was on the front end of my Tacoma.
