    I'm sure it is. They were thinking LEDs last a ridiculously long time. They really should outlast the car.

    What gets me when I read one of these “dummy out of the pram” stories is that when they go off and get in bed with another manufacturer, they think it will be different. As for the cost of replacing these things, it’s a fact that lighting sells vehicles and stylish lighting is expensive. You could build in replaceable modules to a headlight but then the cost goes up. No doubt this guys new car will have fancy headlights and wheels and and.........

    I’ve dealt with or know people that have dealt with other than Mazda and my previous cars, Toyota. The policy of most others is when that warranty ends, it’s up to you now, your on your own. At least Mazda and Toyota look at service history and mileage etc and will consider out of warranty claims.

    LED lighting in vehicles is relatively new and only recently has it been good enough to install in cars where it’s subject to vibration and weather. These poxy Chinese things you buy for the garden look lovely for a few weeks then the go quite literally on the blink. Now ramp it up a bit and the LEDs on cars are being used in headlights as super bright DRLs and headlights. These are diodes! The later Mk1s had the super bright “predator” lights that are the ones popping up faulty now. The 17s on, have lowered the intensity of the predators and utilised a low intensity headlight which if I had to hazard a guess and it is a guess from dealing with warranty cost when I was in the motor industry is to extend the life of those fancy predators. I don’t quite know what is going on with these decorative LEDs. The 16s were banks of singles ganged up into the shape but the 17s look more like many LED rear lights that appear all one stretched light. Is it one LED stretched or is it prisms and fibre optics? Don’t know, maybe somebody can enlighten me (no pun intended).

    Anyway, my point is that I’m not surprised they can play up and not surprised that given the intensity of some of these things, they last as long as they do and don’t really expect them to give ultra long life...... at the moment. They will, given the benefit of development.

    As a slight aside, my ALH headlights at home are much better than the standard LEDs on this rental I’ve got. They have considerably longer range and while these dip instantly like mine, they also go to beam instantly where mine fade up unless I flash them. I can’t get over the fact that these are not bulbs, they are light emitting diodes - astonishing to my tiny brain.

    Just reading up a bit and it seems that the biggest enemy of a LED is heat. They don’t get hot at the front which is why our headlights don’t de-ice. They get hot at the back and are typically installed on some type of heat sink. That might explain why we see very few failures in the UK. A hot day to us is 80f and it’s very infrequent at the moment. On the other hand, summers in the US see much higher temps than this so if you throw in crawling in traffic with the A/C and the engine cooling fans running at full tilt, the temperature under the bonnet gets unbearable to the point you can’t touch it. Not a good home for LED DRLs. Food for thought.

The factory service manual you quoted is for standard halogen headlights in lower trims which use high-beam HB3/9005 (US) or H15 (non-US) halogen bulb with lower wattage.

    In any event if the DRLs are required in Switzerland your choice is very limited and expensive. To fix the LED flickering problem you have to get the whole headlight assembly which would cost about $1,200 MSRP each and you're also going to have mis-match issues on light output and color temperature between new J version and original headlight on your right side. A friend of mine is having the same issue with one month over the 3-year warranty and Mazda North American Operations are only willing to help partially. My advice to him is to just let them go without the LED DRLs as they're not mandatory in the US.

    Your right side LED DRL WILL fail after your left one. At this stage if in Switzerland the DRLs are mandatory, your best option is to find an aftermarket DRL kit incorporated with your fog lights which will be much cheaper than replacing your factory LED headlights.

    Thanks for the info. DRL's are mandatory here in Switzerland, but cars without them just turn their headlights on, so no big drama there.

    I double checked the book today, the previous owner purchased the "4 year and 5 year warranty extension" from Mazda to make the 3 years 5 years. I'll talk to my local Madza garage with the VIN on Monday...

    True true, it's just the default. I've recategorised it more appropriately

    I just joined this forum after researching this issue. My drivers side light was replaced in Jan under warranty. Just this week my passenger side DRL went out, my warranty expired in May even thought Iím under 36000 miles.
    I called Mazda Experience and they said I would have to pay half the cost at $641.31

    I took my car to mazda and yep its being done under warranty. Interestingly the owner of the garage said that they cost around 300-400$ and because that is a high figure he needed to send evidence to mazda before they would authorise a replacement. I'm not about the figure, maybe that's the cost price and not retail. I saw above someone was offered a similar price as a special deal.

    Maybe mazda are trying to recoup their costs by having a margin on them. If they needed to be replaced after an accident I understand but after a failure it's too pricey. Maybe try to mention the cost price and money making to get them to come down on the price. You can only try.
