H7 LED conversion KIT

hi
i bought these H7 LED CONVERSION KIT for head lights and I am having 2013 Jetta TDI.

instructions are not clear.. or I do not understand...

they ask me separate the ring around the bulb, which I did and asking me to pu that ring headlight UNIT.. and then insert bulb through it..

is anyone did this job earlier? please share input..

see this link about what I bought (though I bought from ebay) this guys has given all installation steps and everything hence I am giving this...
when you down 2/3 of the page after clicking link you will see section "H7 installation "

return the garbage.

your headlight has a special holder for the H7 bulb, which is not compatible, unless you find a way to modify the holder to fit the bulb
