Precisely tonight I took my 87 Spider for a drive. It was very dark and I was very aware of how crummy are the low beam HL compared to anything on the road today.
I too, would like to improve the situation but also cannot spend loco amounts of money on this. In my view and for my purpose, the LED maybe have better illumination without straining the electrical system, like you say.
Could you please let me know what your results are?
Thanks a lot.
