PIAA makes some excellent aux lights with a very good driving light pattern. That means they still illuminate well at long distance, but they offer a relatively short-range lateral spread. If that’s what you want, they do an excellent job in LED as well as halogen.
If on the other hand you’re looking for more of a fog light pattern (that’s all very short range lateral spread; no long distance illumination at all), well they still do that but I don’t know about LED. The key here is to look at the light pattern first. The older names in aux lights all tell you what light patterns they offer. It’s the Johnny-come-latelys and the companies who are just selling spec sheet brightness that ignore light patterns, IME.
