The Accel  has EFI and micro-controllers like any modern car, so I'll presume that it is what makes the ding-dong go.  It just gives it a shot of +12V, then turns it off, like it would for any warning lamp.

 

I"ll be there is a way to do this just as simply without the bulb, but it eludes me until I find it.  I'll go look in my Enyclopedia of Electronic Circuits Vol 1, Graf, Rudolf.

My next idea would be an LM3909 with a relay in stead of the LED.

Now that we have a working way to make the dinger work, I checked to see if there are any other cars that can be a source of this chime unit.  The results  are that the earlier  models built around 2000 had them:

 

2000-2005 accent
2000      Sonata
2000      Tiburon
2001-2002 Elantra

 

the models built starting about 2009 had an electronic bell-sound of chime.  Also, the dinger like I have would be located above the gas pedal.

 

Thanks to Cap'n O for the all the fun

I found this simple little circuit.  It's supposed to flash an LED once every 5 seconds, but I'm sure you can change the timing to something better for a ding-dong.

 

Haha, well yeah... It's a 555! I thought you were looking for super simple simple.

 

If you were willing to put something together using a 555, we could have come up with a solution a page ago. 

That 555 circuit only has 5 parts to it, and the ones in my cookbook have a lot more, plus a bunch of transistors, so I will use the blinky light for as long as it will last, and I'll use these long, dark days to etch a few copies of the circuit board. I'd hate to waste the etchant on just one tiny PCB.

 

The 555 circuit still needs  a bit to drive the dinger anyway.

Having tested the Tridon EP-34A flasher unit, I think it would be fine to control this dinger.  You might think that $13 is a little too much to pay for a thing to make your car go ding-dong, but when you consider that you're saving your $100 battery, it might be worth it, especially if you can get one very cheaply from the JY.

Cool. I'm assuming this is one of those electronic flashers we were talking about near the top of the thread?

 

Did your flashy bulb burn out already, or are you just planning ahead?
 

I won't even get to install it for a month or two, o I'm considering improvements or alternatives.

 

Would you prefer  sort-of-random ding-dong of the bliky lamp, or the precise one of the LED flasher?
