Don't bother with halogen, LED's are the way to go.
It should run a small 4-6 LED light no problem, just don't push the watt limit.
There are several in the 15-30W range that should put out plenty of lumens for 230 speeds.
They light up fine when you're moving.
You may or may not see flicker at idle, just depends on how low your RPM is set.

Mounting them is something that you'll probably have to figure out yourself, however...
