When I first bought my car the first thing I changed was installing LEDs into the door lights. That was over 12 years ago and I have always been thinking of updating them. This first design used 4 LEDs they were using in street lights at the time. That string with a constant current of 30 ma.
So I bought a set of NOS door lights to start playing.
It's been so long since I've seen an NOS bulb in a door light here are some photos. The bulb has no part number but is labeled "JAHN UK".
At 12.50 volts it draws 0.371 amps which is 4.64 watts.
