I actually tried all the options I was debating. But I am still using the Silverstar Ultra H4 bulbs.
The PIAA were whiter, but did not throw out as much light as the Silverstar. I tried LED, but the Silverstar beat that performance too. LED is bright as can be, but the downroad light was poor.
The HID kit I tried was by far the best, and I am highly considering another more compact kit. Wiring it with a relay was a pain in the butt, since it was made for a car. Wires were too cluttered up by the headlight, so tight turns could have pinched the wires. But the test drive was awesome. The shroud on the HID was pretty sharp considering what is was, and I was able to see all around me. I didn't see too much light above the cutoff line though, which is good. I also got the 4300k model, so none of the blue you see in most HIDs.
For now though, I am using the Silverstars. It's simply the easiest replacement, and provides good enough light. I will just have to limit my night riding.
