Some customers may complain of condensation/fog inside the front (headlamp/headlight) or rear (taillamp/taillight) combination lights. The recent new models have been fitted with a clear lens which can cause the symptom to be more noticeable, however, it does not affect the performance of the light. This condensation/fog is a natural phenomenon that occurs when there is a fairly large temperature difference between the inside and the outside of the light housing.

Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering lighting on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

full bulletin at NHTSA ↗When dealing with customer complaints of excessive condensation and/or water within the headlamp unit, first determine if all the bulb sockets (including O-ring), seals and covers are present and correctly installed. In most cases you will find that the Bulb Seal No. 1 (A) or HID Bulb Seal No. 1 (B) and Bulb Seal No. 2 (C) socket covers have not been correctly installed or are missing due to improper prior repairs (i.e., customer replacing the headlamp bulbs or body shop not transferring them when replacing the headlamp unit(s) due to a collision). Any damage caused by missing socket covers, HID module seal (D), or missing bumper brackets (E) is not covered by warranty policy.

What owners are reporting 4 most recent
Headlights blow numerous times in a year. When 'operational''the headlights are very dim at night. I researched and this seems to be a reoccurring issue on many Mazda vehicles. I have tried to reach out to Mazda, with no response. This is very dangerous and my turn signals are brighter than my lights. Everyone on the forum suggests the projector lenses that come equipped are faulty. I spent $400…
The headlights are too dim for safe night driving. Bulbs also fail yearly. This is a common problem reported with 2012 MAZDA CX7
No accidents has happened, but the low beam headlights keep blowing out. I have to have them replaced every 3-6 months. Obviously there is a problem. Upon doing search on internet, I notice several complaints on this problem. Lights are not cheap and very frustrating when you are driving at night and this happens.
No matter the bulbs I use, the headlights are always dim. This is incredibly unsafe for night driving.
