A few years ago, I completed a first draft of a technical article, dealing with ways of minimising vision blindspots, which plague 1968~79 VW Type 2s and other vehicles, using a variety of mirrors, lenses and other devices, which was published in two parts, in the bi-monthly VW Type 2 Owners' Club magazine, "Transporter Talk".
I've since considered updating it with further information and I am sure that many of you know of other similar or very different products, which should be included in such an overview.

This digital prism-camera & two-zone monitor, which is a factory-fitted option for various Toyota cars, might usefully be adapted for improving front or rear lateral vision, on a VW Type 2.
This is a more complete colour scan of the LIGHT-SIGHT packaging, showing the use of a 75 mm diameter Fresnel lens, for viewing traffic lights, obscured from normal view by the top of the windscreen
The size & postion of the interior rear-view mirror and one's relative eye level, can themselves introduce forward vision blindspots.
This is a more complete set of images, showing the advantages of the Zanetti twin-lens door mirrors
This picture scan, is an excerpt from my copy the J. C. Whitney Catalogue No. 442D, dated 1984, which was given to me nearly 23 years ago, by an American student named Eberhard Montieth, when he was studying for an M.Sc., at Cranfield Institute of Technology, in Great Britain.
The picture shows an accessory, door-mounted, external, twin-lens, rear-view mirror, of a type which bears some similarities, to those patented and manufactured, by Zanetti GmbH, in Switzerland, for vehicles such as the 1968~79 VW Type 2, 1980~92 VW Vanagon, 1975-onward VW LT, plus other marques & models.
The J. C. Whitney marketed, twin-lens mirror, plus the matching single-lens plane or convex mirrors, were said to have swivelling mirror heads, making them suitable for both left-hand and right-hand door mounting. I wonder if these twin-lens mirrors are still available?

:D Where can I get a Light Sight viewer? I need that!
The windshields are just a little too low at the top for moderd overhead signals. That's on my short list of Bus complaints.

I've gone and put a couple of the convex mirror dots on both side mirrors and have no more blind spot problems. Problem solved for less than $5. |

Minimising or minimizing, that is the question.
Great write-up though! |

"Pram" is a contraction for "perambulator," a device for walking with an infant. One must, however, exercise caution when going off a kerb with a pram. |

That's what I've got too. No more blind spots. |

Right. There might be a lorry coming down the road. |

Bloody hell, that's spot on! What kind of tosser wouldn't be cautious going down a kerb with a pram in front of a lorry doing 60km?!? Sod off! |

Be sure and get the chromed ones from China - no more blind spots even if mirror gets out of adjustment.
You will see those pramz. |

These ones have a blue tint to them. I assume they were made in China, (what isn't)? The tint seems to knock down the glare ...and it's a close match to the paint. |

I would be interested to observe your sudden switch from the left-hand driving seat, to the right-hand passenger cab-seat, to look over your right shoulder, to check that blindspot!?! :)

Judging from the number of pedestrian casualties, quite a few! Although people should always be cogniscent of what is happening around them, sometimes they are not, for one reason or another. Therefore, motorists are duty bound to exercise all reasonable care, to avoid collision with pedestrians and other road users; what the Institute of Advanced Motorists, would call defensive driving.
People, especially young children, commonly step onto the road behind stationary vehicles, so one needs to be able to detect the presence or absence of such people, in the rearward blindspot, close to the vehicle, before attempting to reverse.

What are mirror dots? :?

Thank you, I'm pleased that someone appreciates it.
Whether one spells the word as minimising or minimizing, depends upon whether one is British & British Commonwealth or American! Of course, we British own the copyright to the English language, so we have the final say on the matter. 8)

I vaguely recall that a perambulator (aka pram), is known in foreign parts as a baby stroller or baby carriage, but being a native speaker of British English (or more precisely, English English, in my case!), I am not familiar with all the American translations. :) |

Nigel,
Mirror dots, spot mirrors, there are likely other names for them?!
These things really are the cat's ass, (sorry...cat's pyjamas, bee's knees) as an affordable solution for blind-spots, at least the ones behind you! |

Here is a mention of a similar product, on three of the Mini forums and a subsequent suggestion regarding a company in Cincinnati, Ohio, USA:
http://www.gbmini.net/wp/2003/11/lightinsight_traffic_light_viewer_widget/
http://www.mini2.com/forum/general-discussion/56546-cant-see-stop-lights.html
http://www.northamericanmotoring.com/forums/showthread.php?p=1530446
http://www.lightinsight.com/
http://www.lightinsight.com/our_product.htm
The 75 mm (i.e. 3 inches) diameter Light-Sight, from Metro Products, was available more than ten years ago, through branches of Halfords, in Great Britain, priced at £2·99 (i.e. circa US$6).
Small, high-precision Fresnel lenses, are also available from the following company, but they seem to be rather expensive.
http://www.edmundoptics.com/onlineCatalog/displayproduct.cfm?productID=2040#SpecificationTable
Here's another link to a Fresnel lens for the passenger-side cab window of trucks, to minimise the blindspot, which would be covered to some extent by a downward facing, close-proximity or kerb mirror:

There also appear to be some accessory traffic-light viewers, of a design similar to the the dashboard-mounted traffic-light viewer, which was an option for the 1957 Chevrolet.
Deluxe Traffic Light Viewer, "Guide", Bolt type base with nut, View head is 2 5/8" wide x 2 1/4" high fan size, Arm is 2 1/4" long with a swivel on the bottom and a ball in the viewer head.

Another dash-mounted item was the traffic-light viewer, a ribbed plastic visor that was installed just above the speedometer. Because the roof extends so far into the windshield, it is hard to see overhead traffic lights from the driver's seat. The traffic light viewer captured the reflection of overhead traffic lights so that the driver didn't have to lean forward to see past the edge of the windshield.

Although this is probably more appropriate, to car drivers towing caravans, I thought you might be interested to see a roof-mounted rear-view periscope, which enables one to see rearward, through a caravan's higher front & rear windows:

Notice the rear-hatch mounted, downward-facing mirror, on this Mitsubishi Delica; a facility I mentioned in Part 2 of my article:
