I tried the wireless led lights but for some vehicles this can be a problem. My 2003 Range Rover did not recognise them so kept on randomly flashing. I then modified the car wiring which worked for one journey then the wireless lights went haywire- it is the lights that have had it not the car as I tested them on my other older Range Rover which worked fine

My lights were £50 eBay specials so I guess the buy cheap buy twice applies here. Given up and gone back to standard board now
