I bought this at an auction years ago.  I never used it.  This is how I got it.  There are 4 lights 2 amber and 2 red.  There are two brackets some wire and the switch etc.  The box was opened just like i got it.  The instructions were also acquired this way. and they are falling apart .    Was told it was for an older commercial truck but I really have no idea.  Normal storage wear.  May need some cleaning.  Please check the pic's.  48 US only.
