Just make sure whenever these aftermarket tail lights are added, they fit tightly into the body otherwise you may have water leaking into your boot area thru the uneven gap between the lights and the gap. My previous ride faced similar problem when I changed the rear light resulting in water leaking into the electronic area at the right hand side of the boot. Once i thought the fuel pump is gone but upon checking it was the relay or fuse which was located at that area which was spoilt by leaking water.
