DBRX400

So trying to clarify something basic, do you have to remove the headlight assembly to replace the HID low beam on a 2006 RX400H? I've seen suggestion of needing to go in under front wheel well but I that is crazy tight. cduluk, your posting at top of thread addresses what to do but implies access that I sure don't have with Headlight in place. If headlight assembly has to come off, how is it done? Thanks! Duane
