ONE of the most continuing sources of trouble and an item needing constant replacement on a vehicle is the electric bulb. In a number of recent MoT roadside checks 80 per cent of the vehicles inspected were found to have defective lighting. Those fleets which have to run considerable mileages unladen probably suffer to a greater extent than where unladen running is small. Many styles of lamp mounting have been tried, but only a few have proved successful in eliminating bulb failure —so it remains the problem of the bulb manufacturer to produce equipment having a longer life.
The development of components for the Armed Services often results in higher quality units becoming available to industry and this has been the case with two new vehicle lighting bulbs recently introduced by Osram-GEC. These have resulted from a rigorous test and development programme to produce trouble-free side and tail lights for military tanks, in which application they must withstand very severe vibrations and rough usage.
Both the bulbs are rated for 28V and 7W, and embody twin filament supports and extra tough filaments. They have nickel-coated caps and are available with S.C.C. (No. 874) or S.B.C. (No. 875) fittings. The recommended list price is 2s 3d each.
