Identify Electronics labeled "Flaps"

Hi gents,

I have a partially kit built Topflite Cessna 182 that I bought about 4 years ago. It came with various electronics that are not complete. I have identified some being an onboard glow by EMS Jomar, as well as some 9v and switches for wing lights, a 9v and light for a tail becon, and some wire for landing lights.

I don't know what the device is shown in the photographs. It looks similar to the micro board for the becon, only that had 4 wires (2 from the 9v and 2 out to the bulb. The micro board in the photo graph has a label on it, to connect to a 'Y' harness and attach into the "Flap" channel on the reciever. There are two wires off the micro board, as well as a small adjustment.

I was thinking it's either to slow the flaps, or a better guess would be something maybe with landing lights. Need help with this one. Thanks in advance.

It does have a 9V battery I'd say it does not supply any power to the receiver.
My best guess it used the flap position on the receiver as a switch, for as you said, landing lights on and off.
Light are cool but on a sunny day they can't be seen and on a cloudy day you can kinda see em. I wouldn't fret over them too much...unless you just want them real bad

My guess is a slow-down circuit for flaps. I have such an item on both my planes with flaps, but it is much smaller. That is the only thing I can think of; it may not be miniaturized as much as what I have if it's older.

Thanks guys.

I was told they are the 'RAM Landing Lights 4 8V 2 RAM03'. Judging by this picture from the interweb, the micro board looks right. Not sure why there are only 2 wires comeing off, maybe to add a connector that Y's out to 2 lights? Not sure.

So (me not being electrically knowledgable), is there a way to use these, to go on when the flap servo is engaged WITHOUT using the reciever battery. I don't know if it's just me, but using your reciever battery for lights doesn't seem like a good idea. Is it as simple as disconnecting the red/black wires to another battery, and only sending white to the reciever? Thanks in advance.
