Do they ping on like xenons
The pinging on is due to the bulbs. If you fit HID bulbs, they will, if you leave the Halogens in, they won't.
UPDATE on potential GB - I have a price for 3 sets (under £300 delivered)
Just waiting on a price for 10 sets, should we get enough interest.
Also, my contact tells me the original OEM Xenons are made my Hella, so these are exactly the same as the OEM Xenons in construction, just with Halogen bulbs.
Also, regarding them having a shutter (being bi-halogen/xenon). I'm not sure from looking at them, sorry. I will only know once i've fitted them and can hear the click on switching to main beam. Sorry
