I use a generator light with a cutoff optic, mounted below my front rack so it's not blinding people.
For my road crossings (I've got quite a few in the first 6 miles) I use a Princeton Tec Quad LED on my helmet. Single button on/off, waterproof, easy to operate even when wearing big lobster mitts. I just turn that guy on the first setting (high/photon torpedo) and use it to jacklight drivers so they know I'm crossing, then I turn it off when I'm back on the MUP.
Could be an option for you.
