Dear Sirs, We are in receipt of your favour of the 18th.instant, which has been passed on to us by our Birmingham Branch for reply. The only Bifocal Lamps we make are designed for use in American Headlights having di-symmetrical reflectors. These Lamps are not suitable for use in British Headlights, and moreover, they are only made for 6/7 volts. If you desire to convert a Lucas P.100 Lamp into an electrical dipper by the use of a Twin Filament lamp similar to the Bifocal Lamp we would respectfully suggest that you get into touch with Messrs. J.{Mr Johnson W.M.} Lucas & Co. Ltd, as the angle of dip produced by the uppermost filament will depend on the characteristics of the reflector. We shall, of course, be pleased to collaborate with Messrs. Lucas.& Co, in the production of a Lamp suitable for your purpose, and we are sending them a copy of this letter. Yours faithfully, FOR AND ON BEHALF OF GENERAL ELECTRIC Co., LTD, J.{Mr Johnson W.M.} H.{Arthur M. Hanbury - Head Complaints} Hale ASST. MANAGER, OSRAM DEPT. TO ENSURE PROMPT ATTENTION MATTERS REFERRING TO VARIOUS DEPARTMENTS SHOULD BE WRITTEN ON SEPARATE SHEETS. | ||
