I have not seen any aftermarket LED bulbs that do anything for the driver. There is no illumination whatsoever, but if you're talking about something like DRL's only, LED bulbs aren't a bad choice. They're dazzling bright to look at for oncoming traffic but that's about all they're good for. A friend of mine with a civic replaced his light buckets for one that holds 2 HID projectors and a bulb socketed cornering beam. He's been going through all kinds of the led bulbs for the past 2 yrs or so to find something that actually lights up the side road and nothing so far. He only wants LED to match the color temp of the hid's. If all he wanted was cornering lights, a standard halogen bulb works better.
