TYC 18-5073-01 Marker Lamp

I changed my valve covers and needed a way to mount my spark plug aluminum wire looms to the new valve covers. My spark plug wire holders were bolted directly to the old valve covers. I don't know why they call these marker lamps but the brackets, 2 on the left and 2 on the right mount in the valve cover bolt holes. This allows my old aluminum spark plug wire loom to be attached without being attached directly to the valve covers. Saved me many $ not having to buy a hole new set to trick out my spark plug wires. Came with the hardware except nuts which I bought stainless locking nuts. I don't care what they call them, they work perfect, look good and professional. Great buy!
