Any California residents out there know if turn signals are a legal requirement on ALL bikes or just new ones. My '73 TR7 has no signals. The person I bought it from said they are not required on bikes manufactured before a certain date (kind of like seat belts on old cars or a headlight that isn't hardwired to be on all the time). Anyone know if this is true? I can't find any info on the dmv or chp websites.
