Hi Randall and all,
if you're interested in "bulbs" made from LEDs sitting in sockets which fit
your applications, contact me off list.
We have these "bulbs" for dashboard lighting, rear lamps, brake lights and
turn signal lights. We have an electronic flashing light relay taking care of
the flashing rate and a special hazard warning flasher.
All this is available for 6 and 12 Volts and +ive or -ive earth. We've
specialised in custom-made products regarding lights.
Our bulbs feature very low power consumption (< 100mA) to cite a dashboard
light as example, a light intensity of 12,000mcd (which means about 20 times
brighter than your conventional bulb), a life cycle of more than 60,000 hours
(so this is more or less a one-time investment) and is very shock and
vibration resistant. On top, there's next to no development of heat.
Best regards
Eric

P.S.: You won't find these items in our webshop right now, because this is a
very new product we haven't had time to announce. I can send pics by mail.
Ok, shameless advertising mode off and flame-suit on! ;-)

Yup, twice the heat. I cannot swear that is a serious problem, but I have
seen several cases where the plastic "windows" in the gauges, and the
plastic lenses for the turn & ignition indicators were melted and discolored
from excess heat.

Aha ! That may explain why the #52 bulbs are brighter (if they really are),
even though they consume less power than the original Lucas 987 bulbs.
Lifetime is one of those bulb design parameters that can be traded off
against other parameters, including brightness. IOW, for the same power, a
bulb can be made brighter at the expense of shorter lifetime.
I don't know what the rated lifetime for the Lucas 987 is, but given how
many working bulbs I've seen that appear to be original, I would guess it's
at least 1000 hours. Probably varies a lot too, as a result of that famous
Lucas quality control.
