[TR] LiteZupp LED lights

[oliver]

first, i will admit to being prejudiced - jim at litezupp is a good friend 
of mine.

imho you did not use the litezupp lites.  and if you want, i will ask jim to 
send you one to test and compare if you will promise to publish the results 
on this forum.

they do not have just a few bright spots.  look at Brian's blog.

on an mgb, the lenses are fairly large and you can turn around in the car 
and see the top of them.  in my mgb, they shine birghtly and are quite 
visible from inside the car.  on the TR6 they is also a very noticable 
difference.
