Mirrors
Whats the deal with wing mirrors? Do they only have to be able to kick back it they stick out beyond the wheel line. If so then surely any mirrors on
a locost would be exempt form this.
Thanks

Kick back mirrors are not required if they are within the car extremities. They have to be a min of 40mm high x70mm wide and must be 70mm high at some
point. The need to be fitted a min of 280mm from the centreline of the car (this may only apply to 3 wheelers, I'm not sure).
My guide says they must be E marked but I think this is a bit vague

I wasnt sure if you were saying yep to my question about the kickback being needed or if they are needed on a locost.
I'll have to find out about the E mark now. The ones im looking at are racing style ones, i think they sell them in Demon Tweeks, but also
elsewhere cheaper.

My SVA manual does not say that mirrors are exempt just because they are inside of the extremities of the car. Granted it isn't very clear but
the only exception I can find is one where the mirror is mounted about 2 metres above ground level i.e. high enough so that most people wouldn't
hit it with their head as they walk under it.
It says the mirrors should be "E" marked OR should be equivalent. This equivalency is regarding the minimum sizes and sharp edges etc.
Unfortunately it still says that the mirror should be able to, under a loading of up to 10kg, deflect to within 50mm of the mount surface of the
mirror.
Now I've bought some of the Racetech mirrors (little dingky ones they are too) and they pass everything the SVA book says apart from the
deflection part. They are not capable of deflecting to within 50mm of the mounted surface, not even close! 
So I too would like someone to clarify this area otherwise I've got to source some different mirrors and I like these ones too much!
Has anyone that's passed SVA got any info for us? 
It's very unfortunate that the damn SVA book is so difficult to interpret and we all could be leading each other up the garden path without
realising.
Sorry if that's placed the gatto amongst the piccioni.

Andy,
Think of it in practical terms... the reason the mirrors in 'ordinary' cars have to fold back is to protect pedestrians caught by a
'near-miss' or even a glancing blow.
If a pedestrian got close enough to be caught by the mirror then they'd already have had their legs chopped off by the front suspension!
As someone else said, the only concerns are that the glass is big enough, all edges meet the minimum radius requirements, the mirror is adjustable,
and the driver can see all the markers in the appropriate places during the SVA.
It is in the SVA, but you have to look through the weasel words to get at it.
regards,
David

David,
Whilst I agree with you that in a practical situation a pedestrian would not be worrying about being hit by the mirrors after being maimed by the
wheels/suspension, the fact remains that the SVA book does not give a true unbiased and accurate definition (as far as I can see).
For example on another thread about SVA and mirrors someone writes that the SVA inspector told him that an interior mirror is NOT required if both
offside and nearside mirrors are fitted. The book states, and I quote... "An interior mirror must be fitted unless it would provide NO rearward
vision (e.g. obscured by a solid bulkhead).". This then does NOT say what the inspector said.
I think the only thing for it is to phone up the SVA centre and ask!
I'll be right back!

The official line
Ok, I've just spoken to an inspector at Norwich test centre and ask about the mirrors.
He has confirmed that the deflection test would NOT be carried out on a seven style car as the body line is classed as the outside edge of the wheels.
So as long as your mirrors don't stick out pass this line then that's ok. They DO have to meet the minimum size requirement for the
glass area and that glass area must be encased i.e. not flush to the body of the mirror. Also the 2.5mm radius needs to be adhered to on any edges.
The interior one and the offside one need to be adjustable from the drivers seat (normal driving position). Also you definately need an interior
mirror unless it would not show anything i.e. bulkhead obstructing view etc. You do not need a nearside mirror UNLESS the view from both the interior
and/or offside does not meet the requirements in terms of the markings on the ground that should be visible from the drivers postion. If this is the
case the nearside mirror then becomes mandatory.
So all in all a result for me and others who want to use race style mirrors.
I apologise for taking this thread any further than it needed as Mark had already answered the original question in his first reply. I'll
get my coat... or maybe go fit my mirrors. DAMN NO I WON'T I'M AT WORK!
Shutting up now sir.

There is ALWAYS room for additional clarification, I have not bought my mirrors yet, but now we have confirmation from more than one source, I will
get the bike mirrors I have been after
