I am limited in what I can comment on at this time.
But, I approached the Mfgr. late last year and together we have been working up prototypes using one of my square tail lights and a roundie we bought on ebay. These will be shortly installed in my car for beta-testing in real world conditions, so my car will be the first in the World to have these - .
It is safe to say that they are multi-lamp, multi-function, arrays which will be plug&play, totally non-destructive and reversable.
The advantages will be increased visibility - brighter than current incandescent system, low power consumption, lower operating temperature - no more melted reflectors, and enhanced safety - given normal reaction times, a trailing car at 60MPH will get on the brakes 7 feet sooner.
The Mfgr. is well established producing similar arrays for other classics of all types - euro, asian and american, and has a full dealer/distribution system in place.
That's all I can say for now, except that their introduction will first be announced on this forum.
Cheers!
