RIGHT ON THE BEAM!
Because the “Hublite” is a B.S.A. product, you know in advance that its reliability is absolutely first-class. Beautifully designed, precision-built, the B.S.A. “Hublite” will give you years of brilliant service.
The “Hublite” set is powerful, and strongly made. All the principal components, such as the magnet and electric coil, are stationary. The only rotating part is the hub shell, which serves as a carrier of magnetism and, through its rotation, creates the electric current for the lamps. An effective light is produced at the low speed of 4 m.p.h., and the hub is designed to give a self-regulated output, so that at high speeds the bulbs are not overloaded, and do not easily burn out.
Two Models
There are two models — the standard “Hublite,” wired (as is the normal practice) to a headlamp and rear lamp, with handlebar switch.
The second model includes a patent automatic switch based on an entirely new principle. This switch automatically brings into a battery circuit the rear lamp and a pilot bulb in the headlamp as soon as the speed of the bicycle falls below 4 m.p.h. When the speed rises again above 4 m.p.h., the pilot lamp is automatically switched off and the main head and rear lamps automatically switch into the dynamo circuit. This means that a light is always available—even when the bicycle is stationary. The battery is sparingly used, due to the pilot lamp being automatically switched off as soon as the “Hublite” produces sufficient current for the main headlamp.
