[Healeys] driving lights

[f.ronald.rader at gmail.com (F Ronald Rader)]

I have two front mounted driving lights of dubious quality.
I keep putting in bigger bulbs until we reach 105 Watt.
Those worked best but are melting everything and discoloring the lens.
They are powered by a 150 amp GM alternator so power is not the problem:
Question:
I want two new period looking high powered driving lights for fast
night time driving.
Think Montana!

Any ideas?
XK has new repro Lucas lights but they suggest 45 watt bulbs.
TIA
