Flasher unit classification
The Hella range comprises the following types of flasher units:
Single-circuit flasher units
Two-circuit flasher units
Three-circuit flasher units
This classification is based on the number of internal current/control circuits,
via which the flasher lamps on the vehicle can be switched and controlled.
Hella flasher units ensure control by means of
1. Doubling of the flashing rate (E control)
or
2. Control lamp cutoff (P control)
