| R.R. 236A (100 T) S.H. 723. 10-12-30 G 2947 To HS{Lord Ernest Hives - Chair} from DA.{Bernard Day - Chassis Design} X4350. RE ANTI-DAZZLE DEVICES. DA{Bernard Day - Chassis Design}10/CB11-4-21. Mr Whitehead was shewn an arrangement of coloured glass which he thought would prove very effective in reducing the dazzle of the head lights of an approaching car. You will probably think that it will be worth while to order a specimen, and as the exact type depends on the car to which it is to be fitted, we are sending you the pamphlet herewith, so that you can choose the one you like, and instruct Mr Whitehead, referring to his WD{Mr Wood/Mr Whitehead}1/NJ8-4-21, of which you have a copy.
