Replacing the standard bulb with a LED is easy and makes a huge difference. It might be sufficient for your needs however i would like more light to the offside rear too so am looking to attach a separate reversing lamp to the towbar. bracket....

I’m facing the same issue. Coming from a dual side reversing lamps vehicle (after struggling with a single sided one). Basically I need to add a reversing lamp to the non lit side. Anyone tried anything?
