Should be a quick glance, it should be a look long enough to take in information.I'm an IAM observer, so often go out with people who need to look in their mirrors at my front indicators to know which way to go.
Almost without exception, since I got a 1250GS with the orange running lights, people who go out with me for the first time have complained that they find it hard to know at a quick glance if I'm indicating or not.
I view this as solid evidence that these orange running lights ARE confusing to other road users.
Saying that most Nigels on the IAM are about 85 with glasses anyway.
