A lamp that should work, I just ordered some for a 2000 Villager I am working on, is from
www.mouser.com and has a Mouser Part #: 560-CNW123. Do a search for that part number and when the page comes up click on the "data sheet" for the dimensions of the bulb. The cost is $0.65 each + $5.99 shipping for as many as you want. Also
www.superbrightleds.com has all different size and shape LED dash lamps too. I ordered some of these too just to play with when I have the panel out.
