Removing 1998 Accord headlights

[hunterr83]

I could use some help on removing the headlight piece on the passenger side. I don't mean the bulbs, I mean the actual plastic thingy that protects the bulb. It seems that the unit isn't sealed in tightly so that water gets in when I wash my car. The small gap somewhere along the unit is small enough for water to get in but not big enough for water to easily evaporate out. So after I wash my car, it takes months just for all the water to evaporate. This is causing the right-turn blinker bulb to malfunction. I'd also like to know how I can poke a small hole into the unit to help the water evaporate quicker. I would rather poke a hole than removing the thing. I tried a hammer and nail but that plastic is pretty thick.
