Some observations; the light’s wiring comes out of the end of the light. I removed material approximately a square centimeter in size from the bottom wire end of the bar so I could bend the cord to pass through a hole under the end of the bar. Thus hiding the wiring hole. Once mounted I filled in the divot that was left with silicone. The light’s wires are very fine, 28 gauge I think. I painted mine to blend in but after the fact I think it would have been fine. The price is such that I’ve ordered a couple extra to keep as spares.
