I'm curious if anyone has replaced a light in an E1 rear bumper WITHOUT removing the bumper. Is it even possible? One of my rear lights has failed and I really don't want to pull the bumper in order to replace it. It looks like it will be challenging to get a wrench in there to even remove the light, but perhaps I'm missing something obvious. Any suggestions would be most welcome (even if the conclusion is that I need to remove the bumper).
