Cab lights

I installed my cab lights as well not to long ago. Here's what I did.
My neighbor at my shop had a 78 F350 so I measured the distance from the outside light to the gutter.
Then I removed my headliner on my truck and exposed the 3 slots in the center of the roof support. This is where the factory middle cab light would go. That gave me my distance from the windshield so used that center marker and made my layout.
Most of my planning on the layout came from memory as I have done this before and just simply followed another truck pattern so here's my measurements to make your task much easier.
The factory pattern.
Measure about 4 7/8" from the gutter.
16" OC between outside lights and the 3 inboard lights.
9 1/2" OC between the 3 inboard lights.
Remember to set your middle light for your reference. Lay it out before you start drilling to be sure everything is symmetrical and perfect. Take your time and have a vacuum cleaner nearby because there will be lots of metal shavings to clean up when you are done. Snap a chalk line to help keep a straight line.
Enjoy!
