Hi Brothers, does anyone knows the correct procedure to change over the head light units (L & R) on the TL Magna? I got a pair of colour matching headlight units that I want to put into my car. Any clues? Thanks.

Yea you will need to remove the front bar to get to the screws hidden under the headlight
Tho i'm not sure if it's easier to do it while the bumpers on, i've done it acouple of times with the bumper removed

To remove bumper you need to:
Undo all the bolts under the bumper that holds the splash guard, should be 10mm bolts
Open the bonnent and remove all the plastic clips along the top, use a phillips head screw driver if there not broken as they are cheap and nasty clips
Lock wheels all the way to the right so you have access to the splash guard as you'll need to take the screws out so you can get behind it
Reach in towards front of car and you will find 3 bolts running along the side of the bumper, join of bumper to panel between indicator and headlight
Remove these bolts but remember to look at which way the metal bracket is attached, repeat on opposite side
Bumper should now be loose, pull forward alittle and lift over bonnent latch making sure the bumper isnt catching anywheres
Once bumpe is removed there is 4 screws holding the headlight in, two on top, one infront and one underneith
To put back together just reverse the above
Now I might have left something out as it's been awhile since i've taking the front bar off, but from what i've said it's almost spot on ;)
Would also buy a new set of globes while your at it as they are a pain in the ass to change later
Oh and if your unsure take some pics along the way to recap when putting back together

Hope this helps :)

Many thanks dude! Have a good Easter or what ever is left. :)
