overhead trip computer light

How can I get access to change the light bulb in the overhead trip computer on a 98 ML320?

You can't replace the bulb, you are supposed to replace the whole trip computer!

I am waiting for mine to fail, or someone to give me a failed one, and I will try to fit an LED in place of the bulb; I have done this on other equipment (not MB) and I have always been happy with the result.

It is not a risky thing to attempt as the old trip computer is otherwise worthless.

Can you elaborate a bit?

I thought halogen bulbs work on resistence...LEDs offer very little resistence compared to halogen bulbs, so just doing a simple replace could fry the circuit, right?

What do you do? Put a resistor in series or something?

That happened to me last year. There is no bulb to service so I replaced the whole unit. I still have my old one with the burned out light. Computer still works though. I'm sure if you know what your doing you could fix it.
