N/S (nearside) door mirror question

I think you misunderstood me too David, I never made reference to rap around front lenses, I think I specifically stayed with a mirror with an incorporated indicator repeater in it. phaetonott gave a good example, where these repeaters are fitted into the mirror there is no rap around front indicator lenses fitted to vehicles.   

They may look like rap a round lenses David, but can you see the light emitted from them when stood 1000mm to the side of the rear bumper?

The vehicle manufacturer does not fit side repeaters to a vehicle just for additional purposes, there has to be a specific reason, and I think the above statement says it all really

In your examples above David, I fail to see any of them doubling up when the side repeater indicator fails in service. A close inspection of those front indicator lamps does not look to me like they emitted light that would be seen from 1000mm at the side of the rear bumper. Maybe you can show us a better example from your current pictures.

I am not 100% in agreement with this statement either;

That's why lots of vehicles double up on bulbs wherever they can.....it's called good business. It costs less than a re-design and re-application for Type Approval (around £350,000.00 currently)

Experience has shown over years that poor lighting design has been a contributing factor to collisions and pedestrian injuries. Its not good business that has brought on the changes to lighting systems, it is the law that has changed with experience and brought changes on that the vehicle manufacturer must comply with, hence to make vehicles safer in use on our roads.

As far as cost goes, if you already have a lamp in use, then to redesign it and produce it can't be less in cost, it must be more due to development costs, and if in the longer term the light system proves to be more efficient and has longer term reliability then sales go down, thus business profit reduces.

I was following a Fiat Punto the other evening on the motorway, the offside rear position lamp illumination was not that good and the nearside rear position lamp was inoperative. The best evidence available at that time to show me that I was actually following a car and not a bike was the reflectors, because if the reflectors had not been fitted, that car would have been very difficult to see until you were very close to his tailgate.

Motorways are not always very well lit and combined with poor quality lighting from vehicles, this is where collisions can and do occur.
