I am shopping for a front strobe light. I live in a dense urban environment with endless streetlights and never really need a constant light. Basically, I need a "to be seen" light; I can see the road just fine 99% of the time. I am more concerned about motorists seeing me.

What torch would you recommend? I am considering a Fenix LD20, but I think there might be a more simple solution.

I would like a strobe that is bright enough to cut through the constant streetlights but not blinding to myself or drivers. Run time 3-5 hours is fine for my application (late night commuting). And I'd prefer AA batteries (no battery pack). Smaller body the better. I'd prefer not to order from Deal Extreme -- I need the light soon and I'd rather not order from overseas.

Should I even consider a torch? Or should I go with a PB Blaze 2W if I'm just using the strobe?

Thanks
