Point of these to me is they only draw 22mA on my ammeter rather than 155mA for the lowest incandescent. When you are running out of headroom on your filament supply that makes a nice difference. But they don’t look quite as old school of course. Get warm white to retain your jewel color. And yes they fit fine under the Fender jewels they sell here.

Replaced the #47 bulb in my Fender PRRI with a blue model. It fit perfectly and makes the Aqua/Blue jewel look true solid blue and not white with blue edges.

Very satisfied with this purchase. The leds are brighter than the original incandescent bulbs. ONLY issue is the white led turned my purple lenses blue. I might have to try a red led with a blue lens to get back my purple.

Great lamp bulb solid, bright light. Mix with different colored jewels.

I had purchase a blue pilot lamp jewel for my Fender Hot Rod Deluxe Iv [pilot light, but it looked really washed out with the standard white/yellow bulb. I put a blue LED bulb in and it looks incredible now, just the way I want. That plus the fact that it's an LED bulb is a win/win choice.

Popped right in to my Fender Vibro-King jewel lamp socket with no trouble. Gives a nice even glow, a little less intense than the original incandescent bulb.

Be aware these DO NOT fit in a standard fender style jewel lamp. They are too big and you cannot screw the ‘jewel’ on to the body with these. Disappointed.
