Hello from just over the Canal,
Been looking at your circuit (neat idea), and on paper it looks fine. Adding a couple of diodes won't do any harm, but I'd like too suggest spliting the circuit in two.
Build your fog lamp on circuit, and test that wired to the bike.
Build your flasher unit, and test that on the bike. (supply a temp feed to the bulb)
If each works fine independantly, then when you put them into one circuit, if it pops again, I'd look to try and isolate the supplies from each other again with a couple of diodes. I'm guessing you have a few mutlimeters kicking around, perhaps you can add them in the circuit to see where you are drawing the current which is blowing the AND gate, or putting a couple of small fuses into the circuit to pop before taking out the gate which would help to pinpoint the failure point.
been 10 years since I looked a circuit, just drawing on fault finding techniques.
