LEDs draw about 10% of a regular bulb, a lot easier on that wimpy Multi Function Unit module. Photos of my D1, front light LED, rear seat still factory. I soldered mine in, but they make ones that snap in like a regular bulb.

 

Where did you get it?
How much was it?
How long to install?
Where do you get the "pop" in ones?

 

I think I was in Auto Zone, one of the national chains; it was about $16; it took under 30 minutes to install. www.superbrightleds.com is one on-line vendor that makes the snap in modules.

 

Does it dim after you shut the door like the old bulb or does it just go out?

 

Where does the wire to this light come from? Because I have the light but there's no wire. The garage door opener has a little tab on it with live contacts. Is there supposed to be a jumper cable from the opener to the dome light or is there another pigtail off the harness? Mine's a '98 D1, missing something obviously, probably from the headliner job.

 

It does dim in steps just like the regular bulb. I soldered mine to the two tabs that support the bulb, I think negative was on the right. You can buy ones from superbrightleds.com that just pop in like a regualr "festoon" bulb.
