I am building an Annunciation box for a special project to be used in a vehicle. The signals used to trigger the LED's may be GND or 12V or 24VDC. The circuit I have come up with seems to work on paper but I have not nailed down a dimmer circuit for it. The schematic I attached is one of 24 circuits in this unit. If I can control the 12V feeding the display LED manually I'll have this thing licked . Do I need to control the voltage or the current? And hows the best way to do that so that all 24 LEDS will be dimmed the same amount. I envision that one would hold the test lamp as the adjustment is being made. Also for safety I don't want to completely turn off the LED's. Probably just dim them to half the max lumens.
Any help is appreciated.![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
