Here's a question for all you mechanical engineers. (Or maybe some
friendly and well-informed Mazda QC person.)

I'm building a little controller for my headlights that will allow me to
make them wink and blink and do whatever other crazy stuff I can think
of.

Now if I drive my Miata every day for ten years, and raise and lower the
headlights just twice per day, that's about 7300 cycles. Question is,
might they be engineered to crap out after 10000 cycles, or can I
blithely pop them up and down a hundred times per day with relative
impunity? If I wear out a motor, how big of a hack it it to replace?

Don't ask me why. I don't have to have a good reason.

    - Thanks
