Seriously... I would go through one in 3-6 months in my Tundra.
For the bike, I use the Napa BP1210H4. It's an 80/100 watt bulb that is actually usable on low beam at night, and looks like a jet's landing light in the daytime when you REALLY need it. I got about a year out of my first one.
I used the 9003ST instead of the H4 in the Boulevard. That was well over a year ago. I sold the bike (sort of) to a friend of mine and I know he hasn't changed it yet.
It is super bright. I loved it.
Maybe it's the humidity???:?:
I plan on next purchase going to the Wagner bulb just based on cost alone, especially w/2 bikes in the shed now. Almost a C-note for two siver stars!
