Hey revgo, The switch harness is a elektrotek with a super rocker switch and barrel charge adapter with the cap. The LED blinks to let you know your reciever is on and you can purchase the switch with or without the LED (all comp[onents available through MADISON COMPONENTS) the glow driver is a Mcdaniel with a built in Battery. What you see on the side of the plane is the LED - again shows the plug is hot when lit. It can be controled by a switch on your TX in a number of various ways. The other small black receptacle is a deans micro charge plug. (all included with the unit) but can be baught seperatly. I love the set up it works great. - Steve
