| X.7800 Extract from FJA2/C.4.1.29 LUCAS P.100 HEADLAMPS ON 18-EX (IN FRANCE) One of these lamps failed owing to poor contact of the central plunger on to the bulb, burning the insulation and spoiling the spring. A plunger from an old tail lamp was adapted to the P.100 lamp which has not failed since. | ||
