Point taken Ken, but consider signal lights. They're
essentially safety devices and they're supposed to
be maintained on cars which have been transferred
amongst several owners and are decades old.
Same idea with windshields, I guess also.

I have it from a message on the r...@contesting.com list that Phillips bulbs
produce less RF noise than others.
I can't vouch for that, however.

being unsafe. I've never heard of it,

Re: EMC-related safety issues
I do not disagree but what about the use of mobile phones in emergencies -
should the FCC require all advertisements to carry a warning that mobile
phones cannot be relied upon for emergencies?
I think that would be a great idea as it might even focus the minds
