Hi Joe
Was me with the LED's on my coupe.
No flickering over bumps, even though my shocks and suspension need Joe's magic wand.
Here's more information :
Fitting the bulbThey say plug and play. I say easy enough, but I had to buy a new set of spring clips for the bulbs as the original locations could not be used as the large, wide heat sink got in the way of the clip. I had to fit the new clips around the heat sink, then push the catches into place.
It is a firm fit. They do not have the H1 locating "nodule", but have the diagonal slot to fit in the right orientation. Have not noticed any wiggling/judder of the light as I drive.
I would say, for easier fitting, you can get one with a removable heat sink for ease of fitting with original hardware (see below link from Poland). With the other link the heat sink is fixed in place.
These guys also sell them :
H1 -
Polish site - ZES H1 LED bulbs Not used them - they are in Poland - so cannot vouch for them. They look the same and promise the same Philips ZES LED's.
They do tests of light output, etc. on Youtube, so seem quite a reasonable firm.
Here is how they look with the dust cap back on :
With dust cap back onYou can also see in the video below the beam cut off for each headlight.

Front viewHere below is the difference between the Z-ES bulb I used (left) and CREE XHP50 type bulb, I also tried (right). The right beam is rubbish and curved. The left is focused properly.
ZES left - CREE rightHere is a video of me driving round. I would say the light output is on a par with standard Xenon's and not too much light as can be the case with high power Xenon's.
https://www.youtube.com/watch?v=rZ5SZrxoxKUHeatAfter running these for an hour and driving round, the heat sink was hot (I could hold the heat sink for 2 seconds before it felt too hot). The LED driver box (metal cased) was merely slightly warm - around 25 - 30 degrees.
You get no heat output like halogens at the front of the headlight, it all goes to the heat sink. I believe original halogens get to around 100 degrees +.
These draw 0.75A each, so are much lower than the originals - around 9A for the pair of halogen / "Xenon" bulbs.
As they are LED, they get to maximum brightness immediately.
There are some headlights with the CREE LED's. As above they are rubbish as the beam is nowhere near focused enough.
Also, some have metal braided belts behind the bulb to dissipate heat. The one I tried above got roasting hot (could not touch it as did the LED driver box - way too hot to touch).
Cheers
