Hi, I still have the rubber disc in place. (modified)
The new LED-lamp fits inside the headlight-house with rubber sealing on!!
But then comes the problems with all cables in and out.
From the first beginning I tried usual H4 lamps but with changed supply feed , to get rid of the voltage loss caused of too weak supply wiring. (usual problem on all cars)
So from one of the headlight power supply (3-pole contact to the H4 lamp) I took maneuver current to my new relays with power feed directly from the battery.
Because of this earlier test arrangement, I already had my power connection to the headlamps fed from a place outside the lamp-house. This was now used when I needed to connect the new power-boxes for the LED-Lamps.
I have made a little cut in the rubber-seal just enough for the cable to pass. (almost too little for it really) You can use some silicone-rubber or similar to protect it further more.
The cooling element of the LED is supposed to have the narrow part close to the LED. But I put it in the opposite direction with the cooling wings close to the LED. This is not enough however to get space, because the beam hight adjustment still causes the cooling wings to touch the inside of the headlight housing. I had to look where the problem occurred and remove a little bit of the cooling wing(s).
Be careful not to force the beam hight adjustment so it causes the mounting/fixing screw on the LED to get moved!!
Check that no cables are compressed by accident. I also have put a "systoflex" heat protection, in the headlight-housing, around the cables where I "stole" current to my headlight-relays.
