<p>That's how they _should_ work in all but the first MGBs and I
suspect MGAs. They come on when you operate the switch then after
a short delay start flashing off-on-off-on. This gives the
earliest warning to other road users. They also have a 'bulb
failure' mode where if one has failed the remaining corner and the
tell-tale come on and stay on so you can take appropriate action.
If you fit a 4-way/hazard flasher unit it's then they only start
flashing after a delay from operating the switch, and they will
flash anything from one to four bulbs at the same rate.</p>
<p>Triumph flashers are different again as far as the tell-tale
goes. With a single tell-tale they should be off normally of
course, but if you fit an early MGB flasher it comes on with the
ignition and only starts flashing off when the indicator switch is
operated. The MGB with two tell-tales has additional contacts in
the indicator switch to prevent that.<br>
