I'm afraid I have to agree with your son on the turn signals. Here in geezerland where we live, about a third of the drivers we encounter are severely nearsighted and have the reflxes of 3-day-old road kill. We need all the advantages we can get.

Ain't it neat how we all learn from each other? I have always used light switches from existing (older) cars becase they have a breaker built in and do not require relays. I like your method, though, becase it allows the use of matching toggle switches. All I need now is to know where I can get some of those relays and how to wire them.

With the high stance of your engine in relation to the cowl, you could (someday) mount a small weatherproof tach on the back of the engine. It would serve a valuable purpose and still look "racy". Whatever, I really like the look and proportions on your roadster and am looking forward to seeing it in person.
