Almost any produced in the last 5 years or so, as “super bright” is becoming more and more common. That’s almost certainly what you have in yours, considering your comment about them being like headlights. All you need to do is make the LED resistor more ohms your tame that down.

For front panel "pilot light" applications, I prefer LEDs with the widest possible viewing angle -- which is a manufacturer guaranteed specification on many datasheets. The wider the viewing angle, the greater the likelihood that you'll be able to see whether the LED is on or off, at all positions in the listening room. Not just dead center. Here are a couple example LEDs that specify a quite wide, 120 degree (!!) viewing angle:

3MMLED-GREEN: Jameco Valuepro : LED Super Bright Green Diffused 3mm (T-1) 520nm 5000mcd : Opto & Illumination

3MMLED-BLUE: Jameco Valuepro : LED Super Bright Blue Diffused 3mm (T-1) 465nm 5000mcd : Opto & Illumination
