Side Repeaters

Good Morning All,

From what I can tell in the IVA rules there is no reason to have side repeaters if your indicators can be seen at a wide angle at the front and rear of the car. My indicators are quite far forward Caterham-style and shouldn't cause me any visibility issues.

Am I missing something?

I see quite a few people with wing-mirror mounted side repeaters for IVA.

Cheers,
Josh

Pretty sure they are a requirement,or if not you would need some strange shaped front ones which would allow them to be visible from the rear

Think a photo of your indicators is required here as I am curious how they can be seen from rear (unless mounted higher than the wheel line)

The FRONT indicators need to be visible from the REAR? How did I miss that bit in the IVA manual...

I better dig back into my manual

It's not the actual rear of the car, but must be visible between 5 and 60 degrees from the side. My rough estimate is if you go to the back of the cars length and take a step to the side, that's the sort of angle that needs to still be visible. Page 168 of IVA manual. I'm almost at the stage of fitting mine and had some head scratching where I was going to site the small LEDs I want to use. Wish I had thought of it before purchasing the side mirrors or I would have bought the more expensive ones fitted with side markers.

Not many mirrors with side repeaters built in will pass IVA,as they are not visible from the rear.

Front arches or rear arches are the easiest position to locate them for IVA

Gonna pull the tape measure out and see if I can get away with ones in the rear arches. Is there a position they check from? Behind the car? Car center line?

There is a maximum distance from the front of the car you need to consider,cant remember what it is but it's in the IVA manual

Yep, well kick me in shin, side repeaters are mandatory. Section 23 page 2 of 3.

There must be one a side which is less than 2600mm from the front of the vehicle. 5 degree to 60 degree outboard visibility. Min height 350mm, 15 degree above, 5 degree below visibility.

Insane. I'd love to know what they are there for ...

Book Locost chassis and I can just make the 2600mm rule and fit them on the rear arches

The same reason all cars have them!

If you are sat at 90 degrees to the main road waiting to pull out,if you want to change lanes and cars are overtaking/about to overtake you etc

I thought about on the scuttle just under my side mirrors but think there was a measurement it fell foul of IVA regs. Will have to get back to mine soon.

This is where I put mine, would be better nearer the front of the arch, I passed IVA but it was touch and go, another 50mm nearer the front of the car would be better. Easy to wire up from the indicators on the rear of the arch

Yeah that's no good for IVA,used to pass SVA fitted there but they changed the requirements

indicators need to been seen by traffic in adjacent lanes such as when on the motorway, Side repeaters are required unless your front indicators can be seen by traffic to the side, so in effect you will need them and the need to be high enough up that the rear wheel arch does not obscure them from view.





Never under estimate the ingenuity of an idiot!

I don't know if the IVA rules are any different to the SVA ones, but I put mine on the front cycle-wings and ran the wiring in small, flexible conduit, along the top suspension arm.
