IML: LED Lamp Units

Christopher,
Thanks for the reply. I'll assume for the moment that you've replaced the
front turn signal, tail, backup, and license plate bulbs with LED units?
I've seen LED units w/a grouping of aprox 10 LEDs in use in a friend's
taillight but they were deemed too dim. They were an inexpensive off the
shelf item. Can you refer the brand and/or specs of the units you have in
your '62? I picture them being pretty effective in a '62 tail lamp cone. Are
there LED units that allow for a seperation of LEDs so that one lamp can act
like a dual filament bulb for the brake lighting, or do the LEDs simply
increase in light output? The instant on and off of LEDs has a safety
quotient in alerting the already awestruck tailgater that the massive
gunsight tail lamped vehicle ahead of them has just dropped anchor.
Thanks, again.

You bring up many excellent points, and I agree with you about the perils of
increasing the load on our cars from these new lamps. Especially in the
case of the generator driven Imperials.
But if it must be done, then a relay is definitely the way to do it
properly. There are some very good solid state relays out there that can do
the job without having to deal with contacts that require cleaning or
replacing over time.
If anything, the ideal situation is to decrease the current load on the
charging system for better performance and stability.
(fuel economy too - an alternator at full field will require from 10 to 40
HP from the motor to turn it depending on its rated output)
This is why I have changed the bulbs on my 62 from incandescent to LED
based. Aside from having a shorter time constant when turning on
(Incandescent lamps require a period in time where the filament has to get
hot enough to glow - LED's light up instantly giving the drivers behind you
as much as a half second more to react.) LED's reduce the current demand on
a charging system by 30%.
