I have fitted an audicator to my 3.o litre Roadster S1.
The indicators don't self cancel when used on roundabout exits for instance.
I just ran some wires down to the front indicators and the brake light feed.
the small box of tricks/bleeper unit is screwed to the underside of the dashboard
works a treat. even the hazard lights beep for fifty times and are then silent.
i found that out this week when i ran out of petrol on the M6 because of the USELESS FUEL GAUGE.
Fortunately the AA came to my rescue within 20 minutes.
