Should I get a reflective jacket/coat, or more lighting and reflective strips for the bike? What with daylight saving time ending and it now being pitch black by the time I finish work, I'm not exactly trusting of just a couple small lights on my bike being enough to make me visible to drivers. Seeing a couple cyclists around here wearing them got me thinking, would it be worth my while to get a reflective jacket? I did a bit of a hunt and found a place near here that sells them.

The general price I seem to find is $50 for an uninsulated one, $100+ for insulated. Neon-yellow with reflective stripes, same stuff construction workers would be wearing. Heck, some even have a spot for a name tag :-P

I'd likely get the uninsulated one, just so it can be used in a wider variety of weather, and I can layer clothing under it easier.

So my question is, would it be worth putting my money toward the jacket, or toward getting a new light and some reflective stripes for the bike itself?

EDIT: Re-reading this, I made a mistake in what I was saying. I have a couple lights, they're just not the brightest going.
While the obvious answer is that you really should have lights and a reflective jacket or vest, I'm assuming this is the real world and you have limited resources! Let's go by what conditions you ride in: 


If your route is mostly well-lit and being seen is more of a requitement, I'd concentrate on a decent cycling jacket or safety vest. I prefer uninsulated jackets, but I also have one that's lightly insulated; I sometimes wear the safety yellow jacket over the black insulated cycling jacket. You can also get small, cheap LED be-seen lights you can clip on your helmet or wear on your head if you don't wear a helmet. 
But if you ride in the pitch-black, I'd suggest a cheap safety vest, making do with a non-cycling jacket you may already have, and put the rest of your money towards a good light, something like a Dinotte or a MiNewt. They aren't cheap, but they're worth every penny. 


One final point: 

Reflective gear and a good headlight are more than just safety equipment, they're good PR. I get compliments on my safety equipment, particularly my 200 lumen headlight, quite often, from people in my town (often parents with children), drivers (more than once, someone at a red light will roll down a window to tell me my lighting and safety equipment are uncommon, and keep it up!) and once from two New York City cops (who yelled out "that's the way to do it!" as I rode by at night). 

Yeah, the idiot wrong-way "ninja" cyclists make us all look bad; but cyclists with safety equipment make us all look good. 

Whatever you decide for now, keep in mind that this isn't an either-or choice in the long term: As I'm sure you know, you can always get more safety equipment later on. Yeah, it may seem as if those dinky lights don't do much, but when you have a lot of them, they make you quite visible indeed.
