I have a 2003 express van (1st half of the year) and all of the cluster lights have burnt out. All of the years before this had the pull out style lights and these are hard wired in. There isn't any writing on the bulbs and the dealer can't tell me much. I have found a source for the lights but I'm not sure what the amps or watts are for the bulb.
The one I'm leaning towards is 14 volt 0.1 amp which equals 1.4 watts
If I have to guess I will most likely get that one and the next step down and hope for the best.
I'm sure I will see this question drop to the bottom of the page without an answer but figure it's worth a try.

Thanks any ideas are welcome!
