Driver Madness

Is there any way to mod the 18-wheeler's trailer? Such as making its taillights flash? I know kinda hate how they don't flash when you break or drive at night. Is there any way?

No.
And why the hell did you quote your own post?

A mistake or a bump i guess? Indeed no need to quote your own post one minute later. So i deleted it.
As for your question , i guess it's a coding thing.
