Here's a simple schematic for a warning buzzer that will sound if you've left your lights on. I'm afraid I can't remember where I found it, but if you've got a few spare relays and are handy with a soldering iron you shouldn't have much trouble figuring it out. Of course, I don't think any MGBs came with a door switch, but I just consider that an extra challenge!

Skye, thanks for the idea. I removed the seatbelt safety systems from my 1974 1/2 MGB so I was able to take advantage of the extra, blue, driver's side door switch to provide current to the buzzer when the marker-light relay is thrown. In fact, I was able to take advantage of the always-on-when-ignition-off slate colored wire off the ignition (for the anti run-on valve). I ran the market-light wire from the fuseblock red-wire terminal set, and spliced another jumper to the anti run-on valve wire. Now, the buzzer sounds if the lights are on, the door is open, and the ignition is off!
