For your consideration are THREE vintage “Arrow Safety Device Emergency Warning Light”. You can just make out the Arrow tag on the one light. These are battery-powered lights, taking what appears to be a large round dry cell battery. PLEASE NOTE that the one is missing one of its glass lenses. These lights have some rust and would need some TLC if you intend to re-light them. They are nice old quality vintage items that you are purchasing as-is and as-pictured. Thank you for your interest.
NOTE: I don’t know EXACTLY what these lights were intended to be used for. They have brackets that appear could be used to mount them on the side of something. If anyone has any information on them, I’m curious. Thanks.
