I need to change this marker light on the horse trailer and I can't find anything to lose these bolts. I have a couple screw driver sets with every bit under the sun and I tried hex wrenches both metric and SAE. Any thoughts on what fits these?
If I remember right, these are Philips. Trailer manufacturers use these for assembly because the drivers are easy to center in them. Try a Philips #2. It's either Philips or square bits.
Like Fallon says, use a square bit, a #2 if I remember correctly. I had to remove some screws for something on my enclosed trailer and this worked like a charm.
