Sir,

May I comment on Mr. W. M. Chalmers' letter on page 307?

We have supplied Cibié iodine lighting to many hundreds of Rover owners and, indeed, the Rover Company recommends our units to those owners who require Q.I. lighting.

We would say that with a four-headlamp system fitted, there is no need for pass lamps at all, and if Mr. Chalmers operates the car in Zambia only, the four-headlamp iodine system is adequate.

C. G. Mmst.,
