Remote Control RV's Flood Lights

Question from customer:
I want to use this remote kit to operate 4 ea.-12 volt flood lights on my RV (recreational vehicle) from inside my automobile if backing up at nighttime. I would keep one remote in my truck and one in the RV. Will this be a problem that the remote inside my truck will be at a distance of about 50 feet from the receivers inside the RV?

Answer:
We recommend you 4 models of high power dc remote switch with direct power output (S1PX-DC12) and 2 long range transmitters (CB-4). Direct power output; controlling lights, motors, fans, electrically operated doors/locks/windows/blinds/cars or other appliances. You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance; the wireless RF signal can pass through walls, floors and doors. When it pairs with the long range transmitter, the working distance will reach 500m (1600ft) in the open field. There is no need to worry about the distance. The most important point is that encoding of receivers is same as the code of transmitters. So they can work together.


Wiring:
The wiring is very simple. According to the wiring diagram, each light should be connected to corresponding receiver and place to appropriate position. Each receiver is supplied 12V power supply.


Usage:
There are 3 operational modes. Toggle, momentary and latched modes.
Setting control mode Toggle: Only connect Jumper-2.
Press big button: Turn on the relay.
Press big button again: Turn off the relay.
Setting control mode Momentary: Only connect Jumper-1.
Press and hold big button: Turn on the relay.
Release big button: Turn off the relay.
Setting control mode Latched: Do not connect Jumper-1 and Jumper-2.
Press big button: Turn on the relay.
Press small button: Turn off the relay.
You can choose latched mode since you have two transmitters. As regards the latched mode, it is motivated by relay group. For relay group, only one relay will be on at a time. To be more specific, when you control the light by latched mode, you should prepare at least two buttons remote. Press button A, the light is on; press button B, the light is off.
Button A&B of first transmitter can control the first light. Button C&D of the first transmitter can control the second light.
Button A&B of second transmitter can control the third light. Button C&D of the second transmitter can control the fourth light.
