They are no brighter than stock. Just have the nice white look to match LED headlights

I got these from XenonDepot, which are very similar. Ordered them at the same time as the headlights:

 

$39.99 - 10%

 

Got the 5000K, the 6000K are way too blue. They are a great match. Much brighter than stock, although the very diffusing reflectors in the stock fog lights makes them seem a little washed out. The stock reflectors do that to all the bulbs though.

 

When looking at the truck at night, they look MUCH brighter.

 

Great service from XenonDepot, too.

After reading up on the HIDs I'm not sure about reliability.

I just installed LEDs to replace my stock fogs and they look great. Matchs perfect with the LED day time running lights.

What LEDs match the DRL perfectly? I can't find one as everything I buy (even at 4500k) are too blue for the GM DRL...

The 5000K from XenonDepot are as close a match as I've seen. The 6000K are too blue. I'll try and get a picture later.

The only issue I have had is the orientation of the LED squares. When you twist to lock the bulb in, they must sit as close to 3 o'clock and 9 o'clock as possible. This could mean that you twist the bulb just enough to lock instead of twisting as far as it will go. In my case, if I twisted as far as the bulb would go, the LED squares were closer to 6 and 12 o'clock and the beam pattern was off. I ended up turning the lights on and twisting the bulb until the pattern looked right. Since the install, they have stayed in place. Note: I was told by CS if the bulbs were not snug, you could replace the O ring with the one from the original bulbs. I did not need to do this. Also, if you decide to order them, be sure you are committed to the product. According to their return policy this is not something you want to send back just because you don't like them. That being said, their CS has been excellent.

Went to Install the 9012 LEDs tonight. To get the bulbs at 3 and 9 o'clock the bulb was way to loose. Tried rings off the stock bulbs... Did not help. Any other suggestions?

No, I did not have an issue. I'd call CS and see what they suggest.

There reply was "I don't know, we have a lot of 15 Sierra owners running out lights with zero issues."

 

Also came with the CAN bus add on. Plugged LEDs into it and lights would not come on. Only worked without.... Asked CS about this issue. He said that I would have to change the polarity of the leads on the main end on the CANbus connector.

@2speed, I put those fog LED lights in my 2014 Aierra, took them out before trading it in and haven't put them in my 2015 yet. Looking at maybe that Morimoto Fog kit others have installed.

 

In any event, still need to upgrade my headlights as my friend with a F150 has incredible stock HID lights. Errrrr [emoji20]

Ok Morrislee ....give up the info on the new Led Bulbs!! We need more than a skype name man :) Don't hide it, divide it~!

 

What would you like to know? These bulbs are basically unbranded LMZ bulbs because they came directly from factory with the same heatsink and same diodes

 

They were priced at $69.99 USD a set when I ordered them, ordered 2 sets, was $55 USD for shipping to where I am + $10 USD paypal fee. (then canada border hit me with $33.42 CAD tax)

 

 

I am still to calibrate the offset more to see if I can get better beam pattern for high beam, but it is already performing really good!
