Taillight Covers & Headlight Covers? How do they go on? any security

My friend use to have them on his truck. But they were stolen. But that has been some years ago.

I just wonder if they made locking one yet. If not they should.

 

From what I know of them they do not lock into place and are normally held on with tape of snug fit around the lens. Not very theft proof...

 

Another way my friend's were held on was using velcro that stuck onto the lens. Oddly enough his were also stolen. I would not get them because of the high theft.

 

You could superglue/epoxy them in place to make them more difficult to rip off, but lord help you if you ever have to pull them off...

 

i have a set of headlight blackouts on my 01 monte and it clips on to the top lip of the headlight. the only way someone can get it off without breaking it is by popping the hood.

 

Who makes them????
