Sorry I'm new to all of this, I'm swapping led bulbs in gauges on my motorcycle. I ordered plenty of what I thought was the correct bulbs, but I came across these 3 little guys and I have no idea on a replacement number.. can anyone help me??

 

I wouldn’t worry too much about what they are exactly. Can you measure the working voltage while they are lit? That would tell about the specs a bit. If possible, slide a piece of paper over one while lit and see if you can estimate the dispersion angle (spot versus flood).

I suspect they are standard LEDs using 5-20mA. That would produce plenty of light on a gauge. Just look for LEDs with a similar physical footprint and dispersion angle. They won’t cost much and you might want to order several different options to see which you prefer.

 

Those are LED's. Surface mounted. Just guessing here but the red end is the positive side (the cathode end). Not certain thought.
