I think I've finally solved what for me is unacceptably dim OEM lighting for high-speed night driving.
First, I installed a HID conversion kit. As Flar pointed out, these are problematic because the OEM reflector is made for a halogen bulb. Fortunately, the result wasn't too awful, though it still wasn't quite enough light to suit me. And the resulting pattern was, well, very weird.
So I added on two Vision X Solstice Solo LED lights. I found these on Amazon, here:
http://www.amazon.com/Vision-XIL-S1100-Solstice-Square-Light/dp/B001TQ6DI2/ref=pd_sim_sbs_auto_1The stock bulb on high beam draws 55W. My HID replacement draws 35W and each of the LED lamps draws 10W, so my total is equal to the stock high beam. No worries about blowing fuses.
The light is spectacular. I aimed the main headlight fairly low, because it has the most spillage and I wanted to avoid glare for oncoming drivers. Then I aimed each of the LED's just above the HID center of brightness. The result is all I could hope for, fairly far throw, good side coverage, and, so far, nobody flashing their brights at me. I cruised along the local freeway last night and had no trouble with my aging night vision. I've got to think these things really add to my daytime conspicuity, also.
I really don't like adding any farkles that mess with the beautiful lines of the Empulse, but in this case, safety trumps style and I don't think the result is too much of an eye sore.
I mounted the LED's to a piece of 1/8" thick aluminum stock which I attached to the back of the instrument cluster, using the original lower cluster mounting screws, which were long enough to do the job. I rattle canned the hardware to match the flat black of the lamp housings. These lights are very well made. Their shells are aluminum and are finned to dissipate heat.
Not having my favorite Positaps on hand, I cut into the two wires leading to the headlight and soldered in my leads from the LED's. There was just the right amount of length on the LED wires to make this happen. I taped those connections up with gaffer's tape and buttoned everything back up. It's getting full behind my headlight!
