I personally don't have these, but just remember seeing them on other Grey Wolf TTs when were picking ours up. I would think that there are screws under the plugs on either side of the lights, so I start by popping the plugs out see what happens.
That is the great thing about this forum, there are alot of very knowledgeable people that love to share and help others!
