We have pleasure in announcing one of the greatest scientific discoveries of interest to motorists—a specially treated glass which definitely projects light through fog and mist without back-glare. It must not be confused in any way with amber discs or suchlike fog equipment now on the market. It ends once and for all the terror, the slow speeds and the strain of driving in fog and mist.

Discovered by eminent British Doctor of Science now engaged on Government work

Made by Pilkington Bros. the leading Glass Experts to whom praise must go for the practical appli

to must go cation of many of the exacting demands of the technical formula. If you will post the form on the right we will gladly send you illustrated literature, test reports,. and spectrograph photographs, which explain in non-technical .language the function of this wonderful Nebulae Fog Filter Class that has ended the great bugbear and danger of winter motoring.

Available in all Standard Sizes to fit existing lamps

The fitting of ” Nebulite” Fog Filter Glasses to existing lamps is a simple matter. They are made in all sizes to fit Standard headlamps. Full list of sizes will be sent with literature in return for coupon.
