For aux lights I go with HID. 35w of HID completely bleaches out 35w of LED. I've got an LED headlight and HID aux lights on my Convert. That's how I know. So if you want superior light down-range for a small energy budget, in my opinion, an inexpensive pair of HID from ebay or elsewhere is a good place to start. The downside of HID is that some take a few seconds to warm up to full brightness, and some need to rest a few minutes before they'll light up again. In dip-and-bright driving (traffic oncoming), that can be problematic. I got HID projectors with hi/low gates and plumbed them in to the dimmer on the bike. So I can raise or dip them for traffic without shutting the HID off completely.
