Update: The DRL is working again after drying everything again. There is still a little bit of condensation in the lens but overall the light has been functioning well for several months. For me, it seems, is keeping water from collecting in the bottom of the headlight assembly and using a heat gun on the ballast and wiring connections to possibly evaporate any moisture inside the ballast and connections. I guess this will become a routine maintenance procedure for me until it doesn’t work anymore. It’s still better than replacing for $2k a headlight on a 10 year old car!
HID headlight issue!

Another update: (Long) During our drought the hid headlight dried out completely and worked fine. What I noticed however, was that while the car was parked and had not been driven, the headlight had liquid in it after a single heavy rain. This told me the water must be coming in from the top of the headlight. So I decided to pack the channel at the top the headlight with mortite caulking cord and test with a heavy dose of water from a watering can. The headlight stayed dry on the inside. Water did collect on the top of the bulb access cover (but no water collected inside) so I tried to create a channel in the caulk to increase the depth of the flow channel. The same situation re-occurred (dry headlight, car not driven, heavy rain) and again there was no water accumulation inside the headlight but still some water on the access cover. This may be an easy and cheap remedy as long as the lights are still working. Attached are a couple of photos. I hopes this helps and please feel free to comment about the water collecting on the access cover if you think it may be a problem.
