    You don't say which 433 module you have. I have recently built a remote light controller to switch on marker lights on the gate posts to I can see them better at night when reversing in. I used this item from Banggood. It is a complete remote control system with 4 channels. All I did was to add a timer (Using an ATtiny13) to switch the lights off after 5 minutes if I forget to switch them off. The only thing to be aware of is that if you order the module to be shipped from the uk it comes with key fobs which use the SCT 2260 chip which allows the security code to be changed by bridging links on the board. If you want extra spare key fobs they are only available shipped from China and use a different chip (EV1527 chip) These have a unique code programmed into them. The receiver can be set to recognise them but the button layout is different. I had use the "A" button on the original key fobs but the spare key fobs have this channel connected to the "D" button. The Banggood order code for the spare key fobs is 1018573.

    Here is what you need to know, complete with sample Pic code.

    There is a lot of data and code out there about using these modules with Arduinos...
