Dual filament bulb for P100 headlamp

Anyone know where to get dual filament bulbs compatible with P 100 headlamps on a Jaguar MK IV. Want to get rid of mechanical dippers.

Thanks

Hi Gust,

I’m not sure that there is any point in sourcing a dual filament bulb. Many years ago I adapted the holder to take such a bulb and found that I could focus on one filament or the other but not both. The out of focus filament was useless so I obtained a second solenoid to give double dipping.

As it happens I am now using a double LED with a BA20D base but I have soldered a small brass washer across the the two connections so that both are illuminated together. See: http://www.nostalgiatech.co.uk/LED%20Lighting.htm
