I love the effect of the blinking bulbs in the trees at the American Adventure Amphitheatre. I got as close a look as I dared during my most recent visit and think that the bulbs are #407's which have a built in flasher and are readily available. The sockets, however, a Miniature E10 spiral, don't seem to be available from any source that I can find. Has anyone ever taken a closer look or, better yet, a closeup picture that would help me source the socket? Or, maybe someone has some "inside information"? I really, really want to replicate this effect in my back yard this summer - it's so simple and effective. If you've noticed, they dim this effect during the show which makes it even more stunning. Thanks.
