Yes, from a 85' W201. Looks like for later models they really integrated all the circuitry into a single die, wire bonded & encapsulated the die.

I would assume the incandescent bulb is mounted on the other side of the circuit board & the surface mount current limiting resistor is external and not integrated into the die.

The leds I used are small 3x2mm rectangular leds, therefore 3 leds side by side is only 6mm wide...so no problem fitting through the opening. Than I would remove the lcd display on the other side (to expose the leds) & use small pliers to spread the outer leds apart.
