H7 LED cornering lights?
I am in the process of eliminating all outside halogen bulbs on my car and replacing them with LED.s
The rears are no problem, there are only three BA15S.
But my front ILS headlights has a H7 halogen bulb used for cornering illumination, I have now tried two different brands and both causes lamp errors,
Anyone know of a H7 LED lamp that works without errors?

No I am referring to this light:
screen grab
I know I can use those but the room is really limited and I dont want to mod the light unit.

You need a CAN BUS error free LED. I would not recommend a H7 HID kit for this application. In most cases, you may have completed the cornering before the full instensity of the HID kicks in.
Try to use one of the LED's you already have and install 6-10 ohms/10 watts load resistor in parallel with the LED. Observe the LED polarity.
With reference to Doa's image posted above, the gold colored device is a Resistor to mimic the resistance of the halogen bulb during system bulb check. LED might flicker for a second or two during system bulb check but let us know if it works for you and if the LED is any brighter than stock.
Good luck
Or if you are just after the color, your best bet hassle free alternative is to get a pair of good quality H7 5600 - 8500k halogen (choice of 35 or 55W) for as low as USD15.

Yes I know how a load resistor works, but both bulbs I bought were labled as "canbus error free"
I want a bulb with built in load resistors as I dont want to fiddle with external ones, the rear 21W LED bulbs marked "error free" works fine, but then they are a whole lot less powerful than a 55W H7
HID is not an option as the cornering lights is turned on and off very often and most of the time in very short bursts and as you say a HID bulb wont reach full power in that time

I am going for H7 8500k halo. Good luck

Yes, a standard H7 bulb is 55W
A tip regardning xenonlike blueish white light halogens, try Diamondvision from Philips, a bit pricey but great quality, there is a lot of chinese crap out there.

Vic... here's how the GP Thunder 5800K H7/55W Halo looks like. In my opinion, it matched the color of the stock Low Beam.
I did the passenger side first, bulb came off easily. It might be a no brainer for you and to others. But I struggled and hated myself for 2 long agonizing hours installing the bulb
I can only use 2 fingers with no way of seeing what is happening. I had to use a small mirror and flashlight in broad daylight and visualized in my head how it should be done. The new bulb got beaten up pretty bad with blue external coating fell all over the lens.
I couldn't believed I finished the driver side in less than 5 minutes knowing the space is very limited compare to the pax side
By luck, I guess!

As mentioned in my previous post, I changed mine with GP Thunder H7/55W, 5800K halo. Last night, I went for a long drive in the mountain and I could not tell from inside the car if the cornering bulb is working or not. Regret, I am putting back the stock bulb.
Please lemme know how it worked for yah.

I think MDMercedesGuy is on the right track here, I didnt know that they dimmed in and out when turning, but this makes it pretty much impossible to use HID or LED.s
Fitted Philips Extreme Power H7 instead, sure, they arn´t white but the light output is great and its really helpful when driving slow tight roads in the dark.

How?
OMG, I have now spent about 3 hours now with cut up hands and fingers and cannot get that damn bulb back in? Is there a trick I am missing?? I can't even imagine tackling the driver's side area! WoW.

I ended up going into the dealership and they installed them in minutes (they obviously have a tool or trick) and I think I only paid $15 ea. for them. They installed the bulbs I had already purchased too. Was def worth the money!!

The Euro Philips are also way better than N American offerings. More blue colour. I have to buy mine from Europe as the same Philips here are not even close. I use H7 Philips Crystal Vision.
