I was out driving in the suburbs and I couldn't believe how many bikes were out, let alone without any lights! So now I feel I should have another front light

. I don't do much night riding, but I'd like to have a decent setup when the occasion should arise. Currently I'm using a
Cateye TL-LD130 set on flash (all three LEDs flashing at the same time). What else should I have? I don't need an actual headlight as it's bright as day in the city at night, ..just something that catch driver's attention. Any recommendations?
FYI- I'm using an older model Trek Disco Tech and a Planet Bike SuperFlash in the rear, so I think I'm set back there.
