Re: front light dirty inside
I think you would have to take off the bumper, remove the lamp and see if front clear section can be removed, possibly prising it apart then sticking it back on with sealer after cleaning, as I am guessing it is a sealed unit. This may be a good idea as it seems strange that it is dirty inside, does it mist up? - Maybe the seal is broken and water is penetrating!?
As space is limited i doubt that you could get a bottle brush in with it in situ but worth a try - Take the bulbs out and give it a bash.
