Remote control floodlight - activated from within car.

Random 433MHz proprietary protocol, I should expect ...

I would think so.

You'll often get better lighting by growing your own and feeding it from a separate remote switch.

If you don't mind ebay and overseas sellers with a claimed UK presence then one of these could provide the switching you need from a keyfob transmitter. Best placed in a garage or similar as the 30A relay will be noisy.

Does it have a minimum load specification for it to switch reliably? A suitable LED floodlight may only be 10W, or less.

Another possibility if you can get the home wi-fi from the router where the light needs to be activated. A "smart" wi-fi switch or plug can be controlled from a smart phone.

Whilst you seek a better solution, turning your hazards on can improve matters.

One fix for that is to not rely on lamps with built in PIR sensors, and use one or more stand-alone sensors positioned where you want the detection to happen, and not where you want he illumination.

You can wire multiple PIR sensors parallel:

Fix some reflective strips in place, they help the aim, without needing much extra light. I understand, you can set Alexa up, to switch on a smart switch, when your mobile phone gets within a certain distance of home. Plug a light, into the smart switch.

TLC do a range of Quinetic

Would any of these do?

Although I have a PIR controlled flood light that illuminates the top of the drive once round the slight corner the rest of the drive is in pitch black not helped by being tarmac. I installed a line of LV deck lights down the side of the drive like landing lights and these can be switched on using Alexa voice control as they are plugged into a Smart socket. However since the last few cars we have owned have had reversing cameras I have not needed to use drive lights much.

On a similar theme, one of these Ikea remotes:

If you aren't averse to Google/Siri/Alexa type solutions, it's possible to create an automation that performs certain tasks (e.g switch a light on) when a device (e.g. your phone) connects to the wifi.

Damn, would have saved work if I'd known that diagram existed. I added one facility: used a 2-gang plate so that I can switch on the lights manually, so I have PIR OFF, PIR ON, Direct OFF and Direct ON. Useful if I'm out of range of the PIR for longer than the ~2 min. set (don't want longer - cats strolling past).

They work very well:)..

My PIR light is on a normal switch, if you turn it on-off-on-off in rapid succession, it'll stay on ...

If you have an Apple phone ( I expect Android do something similar) you can like Siri to the various programs used to control smart switches etc.

Assuming you have hands free in your car you can then do it via voice.

I have a whole list of items I can control via Siri ( and Alexa indoors). Outside lights, garage light, some inside lights, electric blanket, …….

You can link lights to cameras, assuming they are compatible and have the function to detect motion etc.

I've done similar. Much easier for SWMBO to work switches that are hard to reach, plus curtains, heating and various plug items (e.g. fan in bedroom). Comes into it's own when you string several actions together in a single command.
