Hi Mo

Cool . I just lifted one side up & when in thro' the wheelarch , I think you can leave the wheel on & just peel back the wheelarch liner , But please when to pull the lamp out make sure you keep an eye on the top edge of the bumper as you could damage the bumper ( i hate to hear about men crying & trying to kick themself at the same time ) , And yea its a very tight fit around the lamp to bumper/front wing , you need to pull & twist , When you get hold of your replacement lamp it a good idea to measure the adjuster to plastic casing on the bottom of the lamp & make them the same , So your lights will not be set too high , its just easier making them the same before you load the light back on to the car . Should only take about 3/4 hour to remove the lamp

Hope this helps
