Product review (5 stars): Economical Replace for a EAV4306084 LED Light - LG Fridge
Mos economical price I could find on line.  Do not purchase the entire light assembly.  You can remove the clear plastic cover after remove the entire light from the fridge.  The video I saw online shows the light assembly coming out easily after removing the 2 screws.  There is a pin on the front side of the light assembly that may come out with a little force.  After that the light assembly comes out easy.  You cannot see the electrical plug snap easily.  Reach under and it moves light a teeter totter.  After you have the assembly on a bench there are two interlocking tabs on the back side that you delicately spread apart to release and then on the both sides you need a narrow straight edge to separate the catch and the clear lens pops off.  Be delicate with the plastic it could break easily.  After putting the light in the plastic cover snaps on easily.  Make sure you hear the interlocking tabs snap together and then reinstall.
