I don't think a light exists with all of your criteria. I think you need to drop one or two. If you drop the $100 criterion, you will probably be happy, because you will have invested in something built to perform well and last long. You want something very good, so you should be ready to pay very good money. I bet you're not cheap with everything in your life, so don't be cheap here. If you're going 40 mph at night, you need to be very serious.
