How can a build a display of LED emergency dash lights?
How can a build a display of smd-5050?
I sell emergency vehicle lights. 12v led lighting I would like to be able select one model at a time (similar to car stereo displays commonly found in retail stores). The display would be a wall with a push button switch that would power 12vdc cigarette lighter outlet. led "flexible strip" I only want one unit to be powered at a time. Could I do this with momentary switches and a type of relay circuit?
