Yet another prototype from the past. This time a rather power hungry dot matrix signage system that used 12V tungsten lamps.
One moment please…

these look very much like t10 w5w bulbs used in cars
you could probably swap theses fairly easily
EDIT: it does seem to be t10
but boy at 175 w per panel this is hungary
At The prince of wales cinema/ jaycee in liverpool the running sign used a punched paper roll running thru a studded mercury bath at mains voltage to run pygmy lamps.
i was told there was also one in dublin somewhere it would still run in 1969
i have a Garden Light Pikes with those im Mod them to Work with LED's and a Solar Sell just the Soldering Issue …. i Need to Buy one
THOSE ARE AS OLD AS ME!
I have been watching all of your videos for like a week now. I am learning so much 😀
I used to have some of those that were a matrix type from a scoreboard.
I work with Lucas Oil Drag Boat Racing here in the states and we have a big LED scoreboard that's solar powered now thanks to me donating them a couple of 100 watt panels and installation.
Illuminating… 😛
Someone was still using incandescent lamps for dot-matrix signage in 1994??
Power it up! Lol
They make LED bulbs to fit that socket. I'm using one on the license plate lamp on my car.
