I've been contemplating swapping my 2014 Limited headlights for LEDs for a while, I knew it was going to be a PITA to install given how inaccessible the bulbs are but I finally decided to take the plunge...
I got these H11 LEDs from OPT7 via Amazon - Amazon.com: OPT7 LED Headlight Bulbs w/ Clear Arc-Beam Kit - H11 (H8, H9) - 60w 7,000Lm 6K Cool White CREE - 2 Yr Warranty: Automotive
They seem very well made and packaged, come with polarity inverters and capacitors (more on those later).
I followed the manual for removing the front bumper and fascia, wasn't too difficult but it's definitely a two man job (luckily I had help)
Removing the bumper
and headlights.. (yes, it needs a wash)
LEDs installed very easily once you have good access to the socket. The black connector is the original power for the H11 coming from the inside of the headlight.
There was no way (or would it be advisable) to install the driver inside the headlight so I drilled a hole in the cap just big enough for the connectors
I used a grommet to keep dust out of the headlight and to keep the wires away from sharp edges, the driver is held by double-sided tape to the outside of the headlight, wiring got tidied up to the original harness.
When I first tested it I got nothing... so I installed the polarity inverters and voila, let there be light. I noticed that there was a bit of flicker, hardly noticeable if you're not looking for it but it was there. The kit ships with capacitors that should solve the issue so I added them to the chain but at that point the lights would not come at all. I emailed OPT7 about that, they very quickly responded saying I might need a relay and they immediately shipped one to me. Unfortunately the relay didn't really help as a, it would be somewhat difficult to install given the battery is under the passenger seat (the jump terminals are an option but not ideal) and more importantly because both headlights would then be controlled in tandem, losing the selective on/off when running them as DRL and using signals. In the week that I have been using the LEDs without the relay I never noticed the effects of the flicker so I will be keeping the installation as-is. I made a note of the height of the light beam cutoff pre-install and adjusted the headlights slightly up to match that with the LEDs installed. I have not had anyone flash me or any other indication of the lights being a nuisance to others. There are also no warnings or anything else indicating CANBUS errors.
Here's what it looks like - all pairs are shot with the same camera settings at Daylight color temperature. I don't notice as much difference in light output but the temperature difference is just as pronounced as it looks in the photos, I absolutely love the way LEDs light up street signs...
The beam cutoff isn't as well defined but it's pretty close
Left side looks cleaner, right side has a little "notch" to it - it is visible when you light up a wall, not so much when driving down a road
All things considered I'm very happy with the results and would recommend it to anyone who's looking for a much more modern look in their non-HID WK2 although the installation really was a proper PITA (it would have been a 5 min job on my VW..).
So if anyone needs a relay for switching H11 lightbulbs let me know, OPT7 were ok with me keeping it and offering it to anyone who might have use for it.
