my dash bulbs were missing so I had to find some replacements, whent to a mom and pop store in the next town over and yep he had them but I had to buy the box of 20.... no issue with me now I have spares.......got Home plugged them in and none of them would work, so I did some research and bought a different brand on eBay, and yes I bought the box...still nothing, then I realized they have to indtalled in the gauges for the ground to work.....moral of the story......I have lots of 6volt bulbs if you just cant find them anywhere else.....oh and I need to learn more!
