Hi,

I think this question has been asked a lot of times on this forum but most of the time the conversation stops abruptly. So I thought maybe we can have all the answers in one place.

I want to change my yellow halogen bulbs on DRL/High Beam to white (6000K) LED. On reading up some of the posts here I see that it can be done but the HB will be of very low output. Others have mentioned that LED DRL won't work unless there is a resistor involved. Has anyone been able to convert their lights to white where both the DRL/HB work fine?

I switched to Philips CrystalVision Ultra (4000K). First they are only 4000K, so not white. Second, when using DRL, they probably get low voltage and so they feel more yellow. HB seems considerably whiter but still not good enough for my taste.

Doesn't work, I tried it
The LED's flicker
I saw a set made specifically for the 3 and the 6 but it involves installing a separate harness to make it work properly

Thanks. If you don't mind me asking, what HID kit are you using?

These
OPT7 AC 35w Xenon HID Kit Slim H11 5000K White Beam HeadLight Conversion Light | eBay

Been using OPT7 on all my cars for years, no issues at all
The ones on my 3 (lows and fogs) have absolutely zero flicker, solid 5000k pure white color, and no relay harness needed
AND their H11 bulbs are the H11"B" style, so the return line doesn't create a shadow

I have been thinking to change all my halogens to LEDs.
For example a JDM Astar, or for example to the ones seen here:

I just really afraid to do this as I have already bought a set of L shaped ebay foglight DRL which at first looked fine, but now I feel I totally spoiled my beautiful car's outfit. Not to mention the fact that those LED DRLS looks very bright and white, while the factory halogens now feels and seems like yellows beside the LED DRLS.

That's why I thought that at least I change the H15 dimmers for some LEDs. I don't really drive at night and while I do it, the reflectors (the H7s) are much more important for me. (so I thought at least I leave them as factory halogens.)

Any suggestion for led high beam?

I just changed the high beam / daytime running lights in my 2016 3 to led and the lights didn't work at first then knowing led to reverse the polarity, so I turned the plug around and works great. The only problem is the high beams are working as they should but now I have no daytime running lights. It's not a real issue, as I never cared for them, but I thought it was strange. I guess the led won't work at half power. I used 9005. Now I need to change the low and fog to led. The ones I got are adjustable and have a color temp of 6500k. There is no brand name. I bought them in Amazon with a 2 year warranty to $15 and change.

The problem is you are using LEDs. The DRLs are the high beam bulbs operated at about 7 volts through the canbus. As LEDs draw a lot less power, the canbus doesn't see them so they don't work, just like LEDs used for signal lights tend to hyperflash. You need to use the proper harness adapter to make the LED highbeams work correctly in the Mazda 3.

I thought about it, but I never liked satine running lights and when one burned out I bought these. I have no warning lights, so I am not looking to correct it. I love the update though. LED lights are so much brighter. This also doesn't require me to alter any wiring on the car. Ok eventually change the whole car over, but only as the originals burn out. I'm surprised Mazda didn't use more led lights when they built them. I also have a 2015 Focus and most of its lights are already LED.
