The wiring in my boat trailer has shorted out and blew a fuse in the truck. I have a new set of taillights and wiring harness for the trailer to rewire it. The problem I have is with the amber side marker lights. This is a 1998 Bass Tracker trailer. How do the side marker lights come off without breaking the lenses in them? They don't have any screws so they have to pry off some way. I am hoping to do this so I don't have to buy new side lights as well. Any help is appreciated. 

I'd thing you should be able to pinch the lenses to access the screws underneath.

You may not have to take them off. On my older Ranger trailer there is a little plug that goes into the light housing that slides out on the inside of the trailer.

My side marker lights just press into the holes. If they have a rubber gasket around them then I would guess they are the same as mine and can just be pulled out with the help of a flat head screwdriver or something similar. 

I have already broken the lense off of one of them to see what is there. It is mounted with 2 screws and the lense was so tight it was not coming off. Now I have to see if anything is available to match up to the original installation.

Willing to bet your trailer need can be found if you have a cargo type trailer sales place near you. Nothing special about any of the markers or bulbs. Are made standard.
