Yamaha B2 lamp option on VU meters
Hello
You can replace bulbs by bulbs no problem and they will live for years . Using LED is possible but the color of the light will change.
Wait for the answer of our member " VINT AGE" who did it on his B2 .
Regarding my point of view none of my B2 use LED for lighting the meters (5 B2 )

I wouldn't use regular LEDs because they'll have bright spots. I used 360° diffused LEDs from Superbrightleds in mine. The whites have the highest brightness. The blues have an almost black light look/effect that I really like and the yellows look the most like the original incandescents but are a little more subdued. I also have one with red ones that I think look real nice.
It's a pretty easy mod to do. I installed them in the same Stanley holders that the bulbs were in and I added a single resistor of suitable value in series with the 12V lamp line to the board. You have to pay attention to the polarity and make sure you install them all in the same way. If you don't like it, it's pretty easy to revert back to the bulbs. :thmbsp:

As I said, I got my LEDs from superbrightleds, (RL5-). The value of the resistor will depend on what LEDs you pick. I'm running mine at about 20mA each and IIRC you'll need something like a 180 ohms 2.5 W give or take. The calculations are pretty simple. I solder 1 end of the resistor in the hole where the feed wire attaches to the lamp board and then I attached the wire to the other end of the resistor.

Yes , I do
They'll work but they won't be as bright ...
Thanks. Contacting the ebay-seller to cancel the order...
I would.
You should be able to find the exact replacements. The diameter is 4mm. There's no reason not to replace them all once you are in there.
I feel like you aren’t guessing on this…
Wont it have a higher wattage (power). P = I * U. power = current * voltage ? whence shine brighter?
