Ok so you should have TIR lenses on the lights but you need to know if they are Wide angle or not.
Take off the grill and front cover on the outer edge of a Wide angle lens is the word WIDE (etched into it) Standard TIRs don't of course.
Actually with the xr15 you get both so check the lens not in the light if you can see the word WIDE standard TIR lens is in the light.
