All, I am in need of the light bulbs for both heated seat switches on the 1990 240 DL. Can someone post the part number, or even better a link to where they can be purchased. I have looked on various vendor sites but none of the bulbs look quite right.

Many thanks

 

I bought a box of "grain of wheat" lightbulbs from 1000bulbs.com and carefully removed and rebuilt all the blown bulbs in my previous 740. This applies to the bulb style with the black plastic base.
Here is my instructable guide https://www.instructables.com/Repair...y-Dash-Lights/
maybe it will help you

 

google for one of the Dave Barton web sites - you'll probably find a bulb guide and part numbers out there.

 

Thanks for the advice folks....I was able to find what I needed with your pointers!!
