Westies, yes, I can do that, I would just need precise measurements of the eye sockets on that helmet.
As for the lights and lenses, when I do the run I'll be cutting the accurate light strips to the correct length and soldering wires onto them. You could buy them in bulk on ebay, but it'll cost more, unless you have more uses for low power red LED strips. And the lenses I make myself on a laser cutter. They'll be available in the kit as well, at whatever diameter you need, although if I get accurate measurements for different types of helmets I can actually list them according to the helmet they'll fit.
