Concerns
with the relative visibility of classic cars
Classic car enthusiasts are increasingly aware that with the growth
of bright Daytime Running Lights (DRLs) on modern cars which
have become much larger, not least from the growth in new SUVs and
4x4s, the relative visibility of a car like an MGBGTV8 is becoming
a real concern. They are also aware that when you drive on UK roads
today you sense that MGV8 is much smaller than many modern cars
which seem to get larger and larger - not to mention the explosion
of even larger SUVs and 4x4s. With the combination of these factors
a classic car driver naturally feels concerned their car from the
1970s is less noticeable on a relative visibility basis and consequently
is aware it can be less easy to see a classic car on the road or in
a rear view mirror.
Here we set out concerns with the relative visibility of classic
cars today highlighting a number of the factors contributing to reduced
relative visibility and the available DRL options for an MGV8.

Daytime
Running Lights have been around for 9 years
Since
February 2011, all new cars and small vans in the EU must
have dedicated daytime running lights (DRLs) to improve
road safety - see an example alongside.
With most DRL installations the rear lights are not
on when the DRLs are on
A survey by the RAC shows DRLs cause unintended confusion
for some drivers because whilst all new vehicles must
have daytime running lights at the front, they are nott
mandatory at the rear and this issue is what appears to
be causing confusion and annoyance for some road users.
Research by the RAC now shows that many drivers dont
turn on their dipped lights or sidelights in poor driving
conditions, perhaps assuming because they have DRLs on
at the front they also have rear lighting on as well.
In an RAC Opinion Panel survey of 2,061 motorists, 62%
said they saw cars and vans driving around in poor road
conditions with lights on at the front of their vehicle
but with no rear lights. Further research on drivers'
awareness of DRLs on their modern car was potentially
very worrying as it found many drivers are driving without
any rear lights believing that because they have daytime
running lights that switch on automatically at the front,
they are also automatically on at the rear too. Not so.
What is relative visibility?
With an increasing proportion of cars on UK roads with
bright front lights (DRLs) in daytime driving conditions |

those vehicles, whether ahead or in rear view mirrors,
tend to be more easily noticed by other drivers more by
their daytime lights than by the body of the vehicle.
Where another car with no DRLs is in the same field of
view, there are growing concerns that cars without
daytime lighting are becoming relatively less visible
and as a consequence may not be "seen" at a
critical moment by another driver. This is a particular
concern for classic car drivers with no DRLs. What
is relative visibility
Another relative visibility factor is the reduced
relative size of classic cars when compared with modern
cars . It's now over the 40 plus years since the MGBGTV8
was launch in 1973 and modern cars have become much
larger on a relative size basis.

What
are the daytime lighting options for classic cars? |

Dipped headlights
Clearly the simplest option possibly with the use of upgraded
halogen bulbs providing brighter daytime lighting. The additional
benefit is that with dipped headlights for daytime use you also
have rear lighting so if road conditions deteriorate, from road
spray or mist, you will be visible to other road users behind
you. See our articles for more details.

Upgrading to H4 headlamps
|

DRLs in the headlamp
This option for retrofitting DRLs involves using a replacement
headlamp kit, comprising a lens and reflector which has provision
for a front sidelight bulb, where a DRL bulb can be used as
a replacement.. If road conditions deteriorate the driver has
to remember to turn on the dipped headlights so there is rear
lighting. See our articles for more details.

Fitting DRLs to an MGBGTV8
|

Separate DRLs
This option involves retrofitting a pair of DRL units available
from Halfords or other autoparts suppliers. The typical location
is in the front grille area. With rubber bumper MGBGTV8s an
alternative location will be necessary. If road conditions deteriorate
the driver has to remember to turn on the dipped headlights
so there is rear lighting. See our article.
