Headlights problems of the 2013 Hyundai Accent

Headlight bulbs keep failing in a rapid and repetitive succession, first incident occurred few weeks after purchase and now while I'm writing this on 2/21/2014 I'm on bulb number 7. I've had the car in at the dealer twice, each service took 2 hours and they were not able to find anything, independent tests confirmed that a voltage spike was occurring which could be causing the bulbs to fail, perhaps from faulty voltage regulator. This is a safety issue at this point because twice the headlight bulbs failed at night, both times on a highway, once with pouring down rain and other time was while passing throughout appalachian mountains. I should mention that high beam was not affected.

The contact owns a 2013 Hyundai Accent. The contact stated that water was entering the headlight assembly. The vehicle was taken to the dealer for inspection where they stated that the failure was normal and advised the contact to turn on the high beam headlights for 45 minutes in order for the water to evaporate. The vehicle was not repaired. The manufacturer was notified but provided no assistance. The failure mileage was 11.
