You'll be fine just the way they are as there is no requirement to have them square to the rear.


Thanks Deezee

I,ve read & re read the IVA manual i have & it still confuses the hell out of me ( not difficult I know ) when the info says position this / position that with ref to table/guide 1 etc etc .

Hmmmm an interesting one this, as such a basic thing could lead to a pass or a simple fail

cheers

Mine has been through iva first time with no problems and all my rear lights are vertical but my reflectors were stuck on the bottom lowest corner of the rear arch as close to the rear tub as possible

They arent vertical and the tester payed them a little attention checking the radius on them, nothing mentioned on the angle though, saying that they arent far off vertical anyway

The tester checked the radius with his gauge and stood to the side to check the angle.

I suppose this situation is one of those " testers interpretation of the IVA requirements" can vary between test stations .

I think I,ll remount them as per the IVA manual then I can,t go wrong

cheers for the input guys

cheers

Vodou panels allow lights to sit at an angle to keep the IVA bods happy,subtle tweekage and angleage here 'n there with extra mango's thrown in for good measure but it was never really an issue with SVA so I never bothered with previous panels.

I've taken a careful read of IVA requirements. Today I found out that the IVA manual diligently recites the regulation by the UN ECE, Regulation 48, "Installation of lighting and light-signalling devices on motor vehicles", Revision 6, pages 45-48 http://www.unece.org/fileadmin/DAM/t...egs/r48r6e.pdf

The sticking point seems to be that the side repeaters should be visible 5 from behind, and 5 below the horizontal.



When mounted on the scuttle, neither the horizontal angle is satisfied (due to the 10 angle in the chassis), nor the vertical, due to the rear arch obstructing the view. I'm afraid bike mirrors with indicators are irrelevant, too, as the indicators are not facing to the rear.

Mounting them on the rear arch, as shown by HandyAndy above in this topic might be OK, but it's just on the limit of the distance from the front of the vehicle (<= 2.50 m), and might be 1 or 2 cm over, unless specifically checked. The book-design rollbar is more than 10 cm out of bounds.

Front wings are out (IMO), because the requirements are not met when the wheels are turned to the side.

The remaining options I see (besides the front edge of the rear arches) are motorcycle stalk indicators mounted on top of the scuttle, facing sideways, or something integrated into the window frame.

I think the best option is to mount them in the scuttle and hope that the tester takes a blind eye on the angles... If not, mount bike stalks on top of scuttle for a re-test and remove after IVA, reverting to scuttle repeaters, which are conveniently there.

The viewing angles requirement seems so pointless in our case. The small repeater, when looking from the 5 rear, 5 below angle, is obscured by a rear arch, carrying a large rear indicator with the 21W bulb.

Here's spud69 explaining the same requirements:

http://www.haynes.co.uk/forums/showt...6722#post64840

BTW, on my roadster the height difference between the rear wing and the scuttle is ~8 cm, and the distance is ~120 cm. Giving the angle of visibility 3.8 below horizon if the repeater is at the top of the scuttle, less than that if mouned lower down on the sides of the scuttle. 50% of the apparent surface must be visible in order to call it "visible".
