AUSEFUL quality for a tail lamp to possess is mechanical strength. The position in which it has to be carried does not help to gnard it against damage, which was one of the reasons for the introduction of the wellknown Rubbolite rubber tail lamps. Restrictions on rubber supplies, however, have been responsible for Flexible Lamps, Ltd., Ridge House, Forest Side, Epping, Essex, the makers -of the Rubbolite product, having to find a substitute, -and this it has found amongst the big family of plastic materials.
The specimen lamp which we have examined, besides being a thoroughly well-made component, is also of extremely neat and pleasing appearance. The usual conception of plastic goods is that they are brittle and, in consequence, have to be handled with care. This is not so in the present instance, as we have proved for ourselves that it is almost indestructible. Efforts to smash a fancy bowl made of similar material resulted in only minor
' abrasions being caused on the surfa:ce. It was quite impossible to crack or otherwise cause serious damage to* the article. The lamp under review is, of much sturdier construction than is the bawl, and the fact that it is used by all branches of the Services should be a sound recommendation of its resistance to damage.
A commendable feature is the ready accessibility' which has been provided to the bulb. The front cap, which is provided with hand-grip ridges, is exceptionally stout and has a coarse thread which instantly registers, so that there is little chance of it ever being stripped.
