One dash light bulb went out. It was behind the 70MPH area. I ordered two
bulbs so I would have one spare. I replaced the dead bulb and put
everything back together. Night time came, I tried it and lo and behold, a
different bulb was out, this time behind the 3K RPM area. Next morning, I
opened things up and checked to see if I knocked it loose, I didn't, it was
burnt out. I put my spare in there.
Next night, I checked the lights again and a third bulb is now out,
somewhere around 5K RPM area (not that I ever go that fast). The bulbs I
pulled out had purple bases, the replacements have black bases and appear to
be the same brightness.
Did the dealer give me the right bulbs? I still have the bag and the "PICK"
paper but don't see which of the numbers might be the part number. I'm
thinking it is 1174H8N80 BULB. I don't have the receipt any longer.
Should I replace all the bulbs in the dash one at a time, or all at once so
I don't wear out the instrument panel screws? What is next, overhead
interior lights? Headlights? turnsignals? running lights? Or is it just my
