This is a genuine Lucas British Prefocus (BPF) or P22D base (12V 50/40W) tungsten headlamp bulb, imported from the UK.
Lucas part number LLB414 is for right hand drive (RHD) cars. Lucas part number LLB415 is for left hand drive (LHD) cars. LLB415 bulbs are no longer manufactured. The bulbs that now come in 415 boxes from other suppliers are actually 414 bulbs. We supply vertical dip bulbs in place of 415 bulbs, which can be used for either application, although they do not come in Lucas boxes.
These bulbs are correct for many styles of original Lucas 700 (7-inch) headlamps, Lucas PF770, P700, PL700 and Le Mans headlamps, and our reproduction PF770, P700 (LHD) and Le Mans headlamps. Some can be seen in Related Products below.
We have bulb holders/adapters, clear and yellow NOS original BPF headlamp bulbs, halogen BPF headlamp bulbs, BPF foglamp and driving/spot lamp bulbs, and later headlamp bulbs. Some can be seen in Related Products below.
