Just so you know:

The Uly headlight is a mere candle compared to the DL's headlights.

I went from a DL650 to a Uly, and I sure miss those dual H4's at night and in the wee hours. I installed a 4000K HID bulb in the low beam, and although it is an improvement over the Uly stocker, it is scattered.

Apparently the 2009/2010 Uly/Lightning headlight assemblies are a bit better than the earlier ones, and can be purchased from American Sport Bike in California (and probably elsewhere, but Al is a top drawer vendor).
