The same fix should exist for your vehicle. The issue is they don't want to dig around for the notice because they are LAZY. Force them to look in the system for fixes for this (for me there were two).
Depending on your level of condensation, they should offer to replace either the vent covers, or the part of the light where the bulb plugs into the housing (seal). I recommend getting the vent covers changed out.
Keep in mind this fix may only minimize and not entirely remove the condensation. These lights put out lots of lumens (on the HID side) and therefore generate a lot of heat. You will need the air circulation.
As I've said earlier, changing out your entire lights and / or drilling into the housing will not solve the problem. I would never allow anyone with power tools near my baby.
