45 watts is the absolute limit for the plastic housing. You can buy a 35watt HID on Amazon for $22 and it will surpass the light output of an H4.

Well I ordered and installed the bulb from the 1st post, and is somewhat than stock. Now I have ordered "this" HID (thanks Tinken), hopefully it'll light up the road better.
Up here, (only about 100 miles south of Canada), At this late in the year, it is pitch black on my commute in to work. (usually at my desk at 5:15am)
Have high hopes.
Thanks.
UPDATE 9/22/14, Installed the $22 HID (xenon) last night. During the install there is a metal "brim" above the light to direct the light downward. With the "brim" attached, it is a zero clearance fit into the headlight housing. Since the "brim" is attached with 2 screws and besides (I told myself), the light I removed didn't have anything to redirect the light, I just removed it.
Should have left it in place, on the ride in, I could see half way up the trees on both sides of the road.
Tonight if I can find that dang-blasted screw that dropped on my garage floor, I'll replace the hood-brim thing.
Oh and by the way, there is SIGNIFICANTLT more light.
