Replacement headlamps for original sealed beams
The original headlamps fitted at the MG Factory were
domed sealed beams which provide a modest view of a country road ahead
at night, so an upgrade with a Halogen conversion is welcome. But
the first step is to find a good set of 7 reflector units that
can take Halogen bulbs. Some kits come with flat lenses but domed
lenses similar to the original sealed beam units are available. They
take a 60/55W standard Halogen bulb which provides a good dipped beam
which has a warm feel like the ageing original sealed beam. Peter
Spurrs' photo alongside compares the halogen
upgrade as a replacement with the original
sealed beam lamp.

MGBGTV8 Halogen headlight
conversion with twin relays
A
worthwhile but subtle upgrade involving installing twin relays to
remove the heavy electrical load on the ageing main lighting switch
and the stalk dip/main beam switch was highlighted by Peter
Spurrs in a note describing his installation of the relays using individual
parts purchased from an auto electrical supplier. Mike Howlett added
definitely fit relays, not only because you minimise the voltage
drop but because it preserves your original switches. Clicking on
your headlamps puts a 10amp load across the puny brass contacts in
the main switch and the dip switch".
