I think the reversing lights are really awful. Every car I've ever owned has had 2 reversing lights using 21w bulbs but for some reason, the RX uses 16w bulbs? The very dark rear screen tint is probably the main problem but also the positioning of the lights themselves - too high up I reckon (maybe this is why they're 16w, so as not to blind cars behind?) They would have been better if they'd been located with the fog lights on the bumper to throw more light on the road.
Having read the numerous posts about improving the lights, or rather, not being able to, I'm thinking of recessing 2 lights in the bumber and disconnecting the existing lights. This way I could use 2 x 21w bulbs (not LED) Another option might be to change the camera for one that operates in lower light conditions but additional light would be the best route I think?
Slightly off thread but still concerning lighting: I think the fog light switch seems daft. You can't have your rear fogs on unless your front fogs are on! If you're at the back of a line of traffic, you don't need your fronts on but have them on to allow the back ones to be on - hope this makes sense?! Why couldn't there be 2 switches (wifes RAV4 has independent switches)
