Thanks very much Gyula. Your explanation is well appreciated.

Hi Naija, you can use 8 indentical modified led bulbs, don't see a problem with that.
Yes, i used the separate circuit, because i had another set of 4 led bulbs that were different as far as forward voltage of led board and i didn't want to see those just sitting around.
I used the PNP for that separate circuit, because i had it on hand from a salvaged powered subwoofer, though if you wanted to use a separate circuit, you can use an NPN and if you use only one circuit, either NPN or PNP will work fine.
Gyulasun gave good advice for the transistor selection.
Thanks for correcting my circuit drawing gyulasun.

I wonder what the circuit output to the bulbs looks like {Across the capacitor} on a scope??  I don't have one yet.

Hello Skywatcher, how do I protect your circuit from accidental short circuiting of the output terminals?

Hi naija, a fuse is the only thing i can think of at the moment.
