Don't understand your post . Side lamps are usually on with any car before switching to main / full beam ?

Main beam and full beam are the same , just different name . You have main beam and dipped beam . When on dipped beam on most cars , if you move the stalk either forward or backwards it will change to main beam and usually indicate on panel. Holding the switch activates the main beam or allows you to flash which is normal
