if you contact toyota dealer they shoudl help you, when i had issues with mine 2 years ago, they fixed it for me but of course i had the dealer warranty. But always contact them.
is better if you use hid retrofit kit to customize your lamps and they will also tell you whats the right to do or not. Here give you the link so you contact them and ask them .

I have a 15 and i have hidretrofitkit building me a custom set of tail lights with some kind of off roads which i love them because i also have off road bar in front. Here is the link if you want to get into more of what they do for our trucks...
I will not recommend the retrofit source due to a few here like me had same issue with their lights, i will just recommend vanquish auto leds and their hids are better or the best ones!
Morimoto lights are not that good ., i had same issue and i decided to contact vanquishauto for my hids and leds on my fog lights. Can't be happier, I will recommend vanquish auto better!
