Very DIY rookie looking to build Hween prop single flash.
I've wired up a 12vDC, 1000ma source to a series circuit of a 1000uF capacitor and a 12vDC RV light bulb. It is my understanding that these bulbs have a built in current limiting resistor.
I want a single bright flash to occur. Then my momentary micro switch will short and reset the cap for the next trigger. It seems to work exactly as I wish.
Am I doing something incredibly stupid ? Will I likely burn up this bulb in 100 cycles, maybe much less ?

Thanks hey, your advice is golden !
