The low beam wiring gets hot and melts the connectors to the bulb connection. The low beam headlights have been replaced 8 times in a year due to low visibility. It's like turning off the headlights but they are still on. It's been going on for years. I've taken it to Mazda and the mechanic told me they had a vehicle there now with the same problem and have not figured out the problem yet. Wiring harness has been replaced to the low beam, the connectors and bulbs replaced fuzes and nothing seems to fix it, the battery keeps needing to be replaced as well, alternator has been replaced. This is a safety issue due to the fact that the low beams are so dim the driver can't see to drive without using high beam headlights to drive and they are just like having regular low beams on.. I've used halogen as well as led trying to fix it nothing has worked
Mazda has messed up headlights and it is very dangerous. I have to drive with high beams on continuously! The low beams point straight down to the road, looks like even with the bumper, you cannot see anything. It looks like you don't have lights on. Took it to dealer and they say it's the housing and it's a Mazda thing and don't do anything to fix it. I have tried every bulb available for Mazda and nothing helps. They need to fix this. I see SEVERAL owners with the same complaints! Please don't overlook this as it is very dangerous and may cause deaths.
During a rainy evening I could not see with the wipers on max speed and the headlights on low beam. I couldn't see the road unless a car was in front of me or I turn on my high beams. My son was in the car with me and several times I had to go at a crawling speed and still barely stayed on the road because of low visibilty. This has happened more than once and I feel unsafe driving now because I feel like I'm driving with no lights on at all these days without rain and rain makes it 10x worse.
Low beam headlights burn out every 6 months, no matter the quality of bulb. Casings are discolored on the inside and light doesn't project beyond about 4 feet, doesn't reach the car bumper in front of me. Cannot be corrected with lens cleaning kits or improved with brighter bulbs. Very dangerous. I cannot see in low light or dark at all. I've had this car since 2013 and it gets progressively worse. Many forums online with same issue reported.
The headlights are UNSAFE! Extremely dim. We have replaced the bulbs and gotten great LED lights but the issue is still there. Sometimes I feel like my lights aren't even on but they are, I cannot see. Please can you fix this. They just keep getting worse. I would have to drive with high beams on just to be safe. I don't drive at night in my car if I don't absolutely need to because of this issue.
Low beam headlights are so poor that they barely illuminate the roadway when driving at night. I've replaced them with Sylvania Silverstar Max bulbs as well as tried LED bulbs and neither help. Makes the car almost worthless to drive at night due to the limited visibility. It has slowly gotten worse since my purchase of the vehicle in 2016.
We purchased a set of headlights and taillights via Amazon from Perde on 12/8/20 after verifying they would fit the vehicle-confirmed with the description provided online. The product that was delivered is defective and presents a fire/electrical safety concern. We installed them, which we had issues initially with the turn signals. While we worked to figure that piece out, we left in the new ones as the ones we had to replace were in worse shape. About a month after they were installed we noticed the headlights weren't working so replaced the bulbs-one of which appeared to be burned/melted. We thought this was a fluke, replaced the bulbs and this worked for a little while. Then about another month passes, my son was pulled over by the police due to both taillights being out. This also presents a safety issue with other drivers on the road not being able to see the vehicle at night. …
For the last 2 years I have been trying to get our headlights to work properly with no success. Even when both dim headlights are working they are so dimm we can't drive with them and if one of them goes out we might as well not have a headlight. I have a vw and if one of it's low beam lights is out it is 100 times brighter than the Mazda with both low beams. This is very dangerous because if we are out at night we have to use the high beams which blinds on coming traffic. I have taken it to jim ellis Mazda twice and the first time I didn't even get home with out the light falling out. Took it back and they assured me if was fixed but it wasn't and now the service rep nor the service manager will even return my call. I have had it to 3 different local shops and they can't fix it either. …
The controls essential for vehicle operation (speedometer, tachometer, transmission gear placement), otherwise known as the center "cluster" controls are illuminated regardless if headlights are on or off. This vehicle is not equipped with automatic headlights, thus making this issue more pressing. When the dash controls are illuminated, you forget to turn on your head lamps to make yourself visible to other vehicles. Mazda stated that the dash controls are illuminated in order to make gauges more visible. My whole argument has been that if I am having even the slightest difficulty seeing my dashboard due to poor lighting (whether it be cloudy, dark, dusk, etc.) my head lamps should be on. If the dash is illuminated, you will forget to turn on your head lamps. This has already caused one accident, and I am afraid that it May lead to more in the future.
My front headlights are so dim I can hardly see when driving after dusk. Even with the high beams on I can only see about two car lengths in front of me. They look fogged up. I was getting gas last week and a gentleman came over and asked if he could clean my headlights...free of charge but he felt it was too dangerous for me to drive. I told him I agreed but that they couldn't be cleaned. He did give it a try but it was futile. The film that seems to be covering the lens is on the inside...or I think it is because it cannot be scrubbed off. It is really scary driving home from work and new light bulbs did not make any difference. I believe it is a manufacturer's defect that if just being ignored.
