Here's something cheap you can try... drive a car from the late 80's or early 90's at night for a few weeks. Then, hop in your FR-S and go for a midnight spin. You'll feel like you've got the light of two suns leading you down the road. There... a FREE upgrade!
I don't get all the complaints about the stock lighting. This car has the best visibility at night of any low-to-the-road car I've ever driven. Of course, I haven't driven much from this millenia..
