VERY RARE VINTAGE AMPLIFIER LIGHTS?

I am selling 2 new, very rare, vintage amplifier lights? Both are in mint condition, I have had these for a long time and don’t exactly know what they are used for. I purchased these from an elderly man many years ago. You won't find these lights listed anywhere online. The lights are adjustable- swivel and have 1/4″ Mono headphone style plugs. $25 Firm. Pickup in Humboldt or I am willing to ship anywhere in Canada for $18.89 at your expense. Cash if picked up or e-Transfer if shipped. Check out my other ads for more interesting items. If the ad is up it's still available.
