Playing devils advocate here. These are the side mirrors I have brought, as you can see there are indicators on the back and the front of the mirrors.  But the IVA manual shows the visibility needs to be this:  But there is an area at about 50 degrees when standing to the side looking directly at the point of the mirror where you cant 'fully' see the indicator. HOWEVER, our audi A3 doesnt have any side indicator other than the one on the back of the side mirror!  So what everyone's opinion on this, will these mirrors be enough for Mr IVA? I dont really fancy fitting more lights as it will look shit unless I get mirrors without the indicators in. |

You don't have to see all of the light but half of it...

Seems a bit of a grey area then, I hate things that are left to an 'opinion' rather than something that can be measured,

I guess it's an advantage, for the IVA at least, to have separate mirrors and side-repeaters - so that each can be positioned to best meet their different IVA measurement criteria/angles. Repeaters can look way better in mirror housing though.

Glad to have helped - they're probably the same as I've gone for (for now). Mirrors and repeaters on even short 'stalks' offer a bit more IVA angle coverage flexibility and can always be moved/changed if they're only clamped like these.

Ok so on our Mevster we had front indicators mounted on the headlights and on the front wheel arches
We had some on the mirrors similar to your suggestion
On daves orange Mevster the Iva chap told us that they did not need to be connected as we already had the correct amount

The IVA manual is quite clear. There is a requirement for front indicators AND side repeaters therefore it is not going to pass if you try to say one bulb is doing 2 jobs. Audi may have 2 bulbs, but then the Audi didn't go through IVA.

Shane where did you get them mirrors from? I'm at the same stage as you. I'm confused will these mirror indicators be ok for a side indicators? I have front ones mounts but side indicators are a headache.

I don't think these will work for the IVA inspector.
The last time I looked at the IVA manual it gave visibility measurements that are mostly from the rear , about 85 degrees to rear and 5 degrees to front 30 degrees to the rear , that's from my aging memory so check... So the visibility test is mostly from the rear , up to side and just a little from the front. ( Edit by Daydreamer )
Most motor car manufacturers have side repeaters in mirrors that appear to be mostly front facing as that is what the average Joe on the street expects but they have a lens that curves around and directs light backwards without being visible to the driver.
I don't believe it matters what proportion of light is directed rearwards so long as a sweep through the required visibility angles provides uninterrupted visibility of the repeated indication.
It is this uninterrupted vision of the repeated indication through the required visibility angles that I think will trip up your selected mirrors.
Most motorbike mirrors with indicators are only replacing the front indicators they are not acting as side repeaters as I don't think there is any side repeater requirement on motorbikes. Your selected motor bike mirrors have a rear facing indication presumably as reminders to the space cadet piloting his custom motorbike.
On that subject of idiot lights to remind pilots when they have left on their indicators, it is worth considering adding some beefed up led reminders if you are using a stock instrument binnacle as these are normally installed in a shaded environment in the donor. In our cars they are exposed and the instrument illumination is not always visible in bright sunlight.

I went through a niggle with this. I had bonded triangular Ford side-repeaters to the frame, but they could not be seen from down by the back wheels. I ended up with coin-sized LED repeaters let into the edges of the front wings.
You cannot have more than one side-repeater for IVA and you also can't have lamps that are not connected as other road users might be looking at them to see if you are turning. I was advised to black paint them out or remove them.
If the Inspector decided that a fix is temporary and it's obvious that it will be reversed shortly after IVA, he may fail it. This may not be 100% fair, but my car failed 1st time on a few things, including a couple of sharp edge covers over my mirror clamps that were pieces of inner-tube, cable-tied in place. They looked dreadful, but met the standard, I thought!
