One of the reasons I didn't purchase a 50th anniv. bike is I knew I would be modifying it to improve it and that would detract from its originality. Further, there was no performance differential and I am not completely enamored with the paint scheme. Before I even rode my '09 bike, I remove the lights. I am in fact on my third set. The look has to be just right for me and I have found the lights that look right at last. Fronts are lowered into Thruxton position with blank out plates. Rears are position next to the shocks. Early bonnevilles had rear lights decoupled from the tail light as well and I believe this looks best. They are brushed aluminum and 23 watts and therefore bright. They are the correct size and shape for the bike...not too small and not too big. They also don't stick out.
They do what they are supposed to and meld into the design of the bike maintaining its retro character.
Here are some pics...they are called large signals made by British Customs:
Rear light is typical Lucas which looks correct for the bike as well. As to lense color...I believe amber is the right color for the T100.
Cheers,
George
