When I fitted my ' 79 Mustang with just such a system I, too was quite
impressed in the improvement in illumination. So much so I fitted bulbed
headlights to the TR6. Unfortunately the units I fitted on the TR6 were cheap
pacific rim units from JC Whitless. After a period of disappointment I changed
them out for sealed beam halogens from my local hardware store. $10 a
piece. Much better even though they were half the wattage.
That's when it occurred to me that a headlamp is more than just a source of
light. It is a light projection system with a critically dimensioned
reflector. The cheap units I bought were not well designed or not manufactured
accurately and even with 100 W bulbs they didn't illuminate the road very
well.
My advice is to stick to known brands be it Cibie, Marchal,Bosch, Lucas,
Marelli. There is junk out there, beware.
