Can anyone help identifying the headlamp bulb fitting for my 73/74 ex USA 750 GT? it’s not an H4, but has a very similar 3 prong plug, but the diameter of the bulb fitting is larger than H4 at around 44/45mm . I’m looking to find a suitable LED replacement as the current bulb is about as powerful as a drunken glow worm. Some photos to aid identication
I got a reply from Dynamoregulatorconversions Who will be supplying the LED bulbs “This is a P45t, forerunner to the H4 (P43t). I sell an adaptor ring to allow our LED H4 to fit your lamp unit.”
