Looking for an oddball item. I am switching a bike with the small 90MM ZKW (Bullet Style) headlamp from a Motoplat ignition (6V) to a VAPE (Power Dynamo) ignition and I am looking for a 12V bulb that will fit in the original lamp socket. Original bulb has a 15MM OD and the contacts are the same as an 1157 bulb, but both retention pins are closer to contacts, i.e. – not staggered like an 1157.
I imagine, I am not the first person looking to overcome this hurdle – what did you use? I would add, I have already spoken with my regular suppliers of odd electrical items and they came up with nothing.
Thanks,
Kevin
--- Responding to my own post in case anyone is looking for the same solution.
I found some 12V LED bulbs that fit the original socket in the "bullet style headlamp" perfectly. The bulb number is BA15D and they are available on Amazon for about 8 bucks each. It is a whole lot brighter than the original and I did not notice any excess heat when I ran it. Best of all it did not flash bulb when running off the 12V 100W VAPE ignition.
