I have a neat Allstate insurance sign that's illuminated on both sides by arrays of white light LED bulbs mounted on small long PCB boards about 140 bulbs on each side.
Some of the LED bulbs, about 10, are burned out and the power supply is also no good.
The LED bulbs are 3-volt. LED bulb dimensions are 5.50mm high, width at base 5.75mm, width at top before round edge 4.75mm and pins are 2.75mm. The bulbs seem to have the light go out the top of the LED. The bulbs are soldered to small thin PCB boards with two wired in series.
The power supply is 12 volt and 2.5amp. It's a Taurus Model VB12030D01, it's 193mm long by 36mm wide and 25mm high.
I don't know if I need anything specific for the power supply. The power supply sits in the middle inside of the sign but it could be external, don't see that it would matter.
Thanks...
