This thread had made me chuckle a few times so far. Les posts that anyone who doesn't agree with his opinion must live on a another planet, and then retorts back that other people were rude to him in reply ... lol.
It seems that regardless of whether the lights are bright enough or not, there is no legal requirement for them to be there at all. So I'm just wondering what the OP was expecting Lexus to say or do? Fair enough that some other cars/brands have better ones, and that means Lexus should do what? They are not going to do a recall when clearly from this thread there are those that think they are fine and those that think they are not. No idea why that should result in insults, but I guess that is how some deal with differing opinions to their own. They may offer assistance in illuminating the way when reversing, but if they were "meant" to illuminate the way, surely we would all have headlights on the back of our cars, with the appropriate legal operating parameters around them (like headlights do)? As far as those saying they are not there as a warning for others, why do you think they are white and not some independent colour of their own? It is so that you can make the connection between headlights and reversing lights and make an assumption that the vehicle may be moving towards you (rather than red lights that would suggest they are moving away from you). So they do potentially fulfill a dual purpose, "If" you have them and they are working, which they don't have to be, or they are bright enough, which they don't have to be.
