Apparently I have purchased halogen headlight bulbs part number 170-957H, from the same company, but with the Little British Car Co web address. I was very pleased with the improvement in light output. I am now interested in their LED options for 35-38 Fords, part numbers 170-754L and 170-754LP. What part number did you use, and how does it compare to incandescent bulb light at night?
I went looking through their website to find an LED option for the earlier bayonet base headlight bulbs like the 33 uses without success, but I may have missed something.
