O finally got my light open today ...and here is the thing , i didn't actually bake them !!! I used hit gun !!!!, I was directing the heat to the back of the light to dont burn the leans!!! I also found 2 great tools wich help me a lot . Pick tool and house separator tool . It took me about 20-25 min for each side to open and clean them from the left over glue .
Its pretty easy just make shore you don't pray on overheated housing , that will deform your light back cover , just take your time start from inside (grille side ) heat and l lift the leans just a little and heat it again etc .
