Headlamps - 7" or smaller?

[Josh]

Hi

I've been looking at headlamps and I'm not really a fan of the 7" after seeing them on some 7's at Stoneleigh. Does the IVA allow for smaller diameter lights (can't find anything in the manual about it ) ?? I'm looking at these 5 3/4" lamps - http://www.cbsonline.co.uk/complete-...ac4-1654-p.asp

Will they be OK?

cheers
