Michael--

Thank you for the additional information and I hope this issue did not bear
too heavily upon your thinking during your Christmas celebration.

As I believe I said in my last message the LED bulbs that Moss sent me are
about 5/16" longer than a standard  incandescent 1137 unit and while they
may work on later cars that have rounded lenses they will not fit under the
flat tail light lens of a 100.

I may not have been clear in my original posting but a number of years ago
I electrified the reflector pods on the rear deck and, using the conical
plastic lens from later cars, I transferred turn signal function to them.
(I also have a free-standing LED strip wired as a third brake light
discreetly mounted to my hardtop below the rear window which is very bright
and attention-getting).

In any case since the tail light performs only running and brake light
function I only need to find shorter LED bulbs that are compatible with the
stock lens and since there is no flasher function I will not need a
ballast.  If and when I find an LED bulb that fits within the reflector pod
I will then deal with the ballast resistor issue.  In the meantime I am
sending the LED bulbs and ballasts back to Moss for a refund, and will
suggest that they not sell them to fit 100's without mods to the lenses.

Many thanks to you as well as others who have posted suggestions on the
topic.

Best--Michaer Oritt
