Center the middle marker light to the middle of the cab. 5" back from the drip rail edge.

From the center of the middle marker light. It is 7" to the center of the two center outer markers.

From the center of the middle marker light it is 14 3/4" to the center of outer marker lights.

My markers are 5" from the front edge of the drip gutter to the front edge of the light lens. This is all lights. They all hold the same spacing on this measurement.

One thing I didn't add if your truck has a cargo light on the back of the cab that is where you can feed the wires from for the markers. It gives you access between the inner and outer roof panels.


Here is the best one I have uploaded. If you want a better one let me know.

The duallys came with factory upper marker lights.

There is no reason to pull the headliner. All you will be seeing is a lot of sheet metal with no access to the area the light wires would run into.

I can get a pic of a inside roof with the headliner removed. My replacement cab has the headliner out of it.

Pull the cargo light out. Then you have access between the two roof sections to run wires. Pickup power for the wire from the headlight switch.

While your in there also install a relay and off load all the light from the headlight switch. That way your not burning up switches and headlight wiring plugs. It is a noted common problem on these trucks.
