Cibie headlight conversion
David Biddle (Chartreuse 2839) from Buckinghamshire
provides a useful note on his long term experience with the Cibie
replacement round headlamp units. (Mar 06)
Cibie 7 inch round headlamp units with halogen bulbs seemed
to get members' votes as the preferred replacement unit for the MGBGTV8
- see V8NOTE324 - so I thought a report
from a long term user of these units might be helpful. I fitted my
first set of these light units in 1990, when my rubber bumpered model
had done some 50,000 miles. The total cost of two light units and
two halogen bulbs from a motor factor amounted to £43.01 including
VAT. I fitted the units myself without any difficulty, although I
took them to my local tyre depot where they set the beams somewhat
more precisely than my 'chalk marks on the garage door' approach!
I was very satisfied with the performance of these light units and
I think that they are without doubt the best light units of this size
available to us.
After a dozen
years of use, I felt that the beams had lost some of their lustre
and so in 2003, with just over 92,000 miles on the clock, I decided
to replace them. This time I purchased the same specification light
units over the internet from Classic and Rally Services at www.cars-gb.com.
For my RHD rubber bumper car the Cibie headlamp units are Model 180
and include main/dip and side lights but they are also available without
the sidelights for chrome bumpered cars. At that time, I paid £38.82
including VAT for a pair of units and the 'next day delivery' charge
was £6.90. The current price would appear to be £43.56
including VAT for the rubber bumper version and £45.10 for the
chrome bumper unit plus delivery. They are also available for LHD

Cibie H4 headlamp unit fitted to a rubber bumpered MGBGTV8.
From the tests that I have seen, there is quite a variation in performance
of the halogen 'bulbs' and, after considering the test results available,
I chose the Osram Silverstar H4 Halogen bulbs at £13.64 including
VAT for a pair. These are claimed to be 50% brighter than the standard
H4 halogen 'bulb', but are still road legal.
An additional modification is to fit the US model headlamp rims
which have spaces which enable the beams to be adjusted without
removing the rims. These were fitted by Geoff Allen soon after I
acquired the car, but as they are so useful it is extraordinary
that BL did not fit them to all cars produced at Abingdon instead
of only those for the US market? Geoff Allen also found me a set
of US specification side flashers, which are a life saver in today's
traffic conditions. I found that the standard flasher unit was not
up to powering three flashers on each side of the car so I have
fitted another electronic flasher unit which makes a huge difference
to driving pleasure in traffic.
