From years of bicycling around urban areas at night and also a penchant for everything black, I have cultivated a few tricks, which I use on my older ('89) motorbike that I just got.
Go to some hardware/hobby/big box store and find a Rust-o-leum paint that is transparent and reflective. I use that on my fenders and front side of my mirrors and such. It will give whatever surface you apply it to a slight gritty texture and look, which is why I use it on more obscure areas. Also look for 3-M (or other brand) reflective tape. In Canada, the Canadian Tire stores carry it (others do as well), but it is great and comes in black, red, silver, and probably a few other colours. Apply both wherever you can (the helmet is a great spot!)
Also, something that requires a little ingenuity and work, mount extra lights to your bike. I am in the process of adding a strip of red LEDs around my tail to supplement my existing tail light.
Get the brightest bulb you can for your headlamp.
Ride with your high beams on at night. Make sure your headlamp is aimed properly. If you need to 'flash' a driver ahead, you can do a quick throttle off throttle on thing (if it is safe to do so!), that will make the nose dive and rise, and potentially flash an oncoming (or otherwise offending driver) to be more aware of your presence. That is of course if you can't just flash your high beams.
Being on two wheels at night is just more risky. Ride safe and make yourself visible.

This is my bike (with fairings off...), with the reflective paint on rear fender only. Looks flat black during the day. Camera flash lights it right up (same with any car lights, street lamps, etc.)

What it looks like in the day...
