I bought and installed these in my van's dash back in March, if memory serves I needed 11 for my van, so I bought 2x 10 packs and the other 9 bulbs went into my car: https://www.amazon.com/Partsam-Bright-Instrument-Cluster-Dashboard/dp/B00KT1BH1Q/ref=au_as_r?_encoding=UTF8&Make=Dodge%7C40&Model=B250%7C2747&Year=1991%7C1991&ie=UTF8&n=15684181&s=automotive&vehicleId=2&vehicleType=automotive
Working great so far, they are really bright. You can tell they are on during the day, and man do they look good at night! My only complaint is I need to open the gauge cluster up and seal around the "Check Engine" light, enough of the light sneaks through whatever barrier is there to make the check engine light always glow slightly. It has punked a few people, my mechanic included.
When my check engine light kicked on a couple months back for a O2 sensor malfunction there was no doubt it was really on then.
Only thing to note is they are polarity sensitive, had to take a couple back out and turn them around in the mounting socket to get them working right. No big deal.
