This is a 1929 ignition switch assembly with a light to see the map meter and it does have an amp meter which is a nice thing to have on a battery ignition bike.
This is a 1928 ignition switch set up, no amp meter or light. My Harley is a 1928 J model which would have this set up but I am thinking about how nice an upgrade it would be to have the amp meter. I don't want to end up with a slapped together motorcycle but on a rider these things are important just like having a front brake. 1928 was the first year for a front brake on the JD line up and coincidentally the first year for Indian as well. Probably not by chance !
