There are many things you can do, drilling a hole is a last resort. I dont know if your model has replaceable gaskets but my 88lx housings were adhered together and the joints had been compromised so I resealed them with silicone and have had no problems since. The idea is to seal out any moisture, I also used silicone grease on the bulb seals. About the yellowish tinge, I assume that is the UV effect on the plastic, I used fine sandpaper, then rubbing and polishing compounds to take the worst of it off, also when you have the housing out of the car, use a bottle brush and soapy water to clean the inside of the housing. Now, after all that being said, the easy way out is drilling a hole or replacing with aftermarket housings, although I'm not sure of the quality of those things.
