My rear blackouts sometimes slide as I drive, is there any tricks to keep them in place? Thanks.

 

Get some double sided tape.

 

Velcro, in case you need/want to take them off.

 

There is a top lip that goes over the actual light on the blackouts. I took a power drill and drilled a small hole through the blackout and through the top piece of the light(the black piece) and it is not noticeable when the hatch is down. I then took a ziptie and placed it through the two holes and tightened it, my blackouts don't slide at all anymore.

 

Instead of blackouts you can just get some RC car tint and spray them. I did that to my mom's ss and it looks clean as hell. Comes off with rubbing alcohol if you don't want it also.
