[urq] Replacing rear lights with darkened units

[colin cohen]

I started the process this weekend and have discovered that my existing rear stock lighting units are cemented to the bodywork with a black rubberized material.  Has anyone who has done this swap found the same thing as I cannot say that I had noticed this before on my car let alone anyone else's?

I am afraid that the process of removal may break the plastic or damage the bodywork?

When you installed you new lights, did you replace the sealant and if so, with what?  RTV?  Silicone?
