Fitted some new LED side lights to the 911, and after fitting i've noticed that most of the time, the indicator and side light do not work, they either both work or both don't work

If I go over a pot hole etc, it might come back on, but at the same time, if I have the main lights turned on, they switch off and back on themselves. Just happening to one side of the car??
I've removed the headlight again, and fitted it back in again to make sure that it was in right, all the pins etc are fine, anyone else have any other ideas?

Noob thing but the bulbs haven't been checked, I think it's a connection issue as all the lights turn off if I go over a pot hole/speed hump at night including the Xenon, but only for that side..

Any ideas please?

 

Take the bulbs out and bend out the contacts. Sometimes, the LEDs are slightly smaller than the original bulbs and don't provide good contact.

 

I'll try that, but that shouldn't stop all of the lights in that headlight stop working should it?

but thanks ,new clutch goes in on monday and I can enjoy the car again!

 

I missed that part of your post. No...the LED sidemarkers should not impact your headlights. I had that problem a while back and it was because my headlight was not locked in properly, but you said you already checked that.
