why $1000? if it's unsafe it's unsafe with $100 of conspicuity gear. But since you asked, flourescent/reflective yellow vest. Dyno light with switchable output. I've got a SON generator with LightOn! headlamp and tailight set on low most of the time. Petzl headlamp on helmet with PB Superflash on helmet and bike. Petzl headlamp on strobe is almost like a xenon strobe.

The vest and your ability to ride in a straight line are the most important parts. After that the lights. But if it's unsafe, it's unsafe.
