Hi all,

Well, the day was nice, and I figured it was time to install my clearance lights. My truck is a regular cab. I removed the pillar trim and handles, the sunvisors and the sunvisor inner supports, the 2 push pins, the rear clothes hangers and the dome lamp. I then wiggled out the headliner.

I measured the roof and found the exact center, and then measured out 7 & 7/8" for the next pair of lamps, and then 12 & 7/8" more for the outer lamps. All lamps are 3 & 9/16" back from the windshield rubber--that is 3 & 9/16" from the windshield rubber to the front edge of the lamp. The mounting studs and electrical connector are another 1 & 1/2" back from the front of the lamp, for a total of 5 & 1/16" from the windshield rubber. That is where the holes are drilled.

I own a service station, and have quite a few F-250's with clearance lamps & F-350 dually's come in for diesel, and I have measured many of them, and those were the measurements I came up with.

I drilled the mounting holes to 1/4" and I used a Greenlee 1/2" conduit punch for the hole for the electrical connector. That punch makes a perfect 7/8" hole, and it went through the roof panel like butter. I mounted the lights and then ran the harness down the right side pillar, and plugged it into the connector behind the right side kick panel. I turned the lights on and everything lit up like it should.

I then reversed the dissassembly procedure and everything went back together perfectly. The whole thing took me 4 hours--no real problems at all. Just remember---all 5 lamps must face straight forward, not follow the curvature of the windshield. All 5 lamps sit perfectly flush with the roof using my measurements. Here are a couple of pictures I took.

why would you want clearance lights on a truck? I always thought of them as roof warts.

 

Sorry if that came across a little rude, I just never understood the reasoning. Several of my buddies have them so I'm probably the odd man out.

 

those look very nice i am going to do mine shortly thanks for the measurements

 

People just like the look, as do I. Good job looks really nice.

 

If you pull out the headliner I believe the front roof brace bar has holes stamped so you don't even have measure, just finish drilling through the roof skin.

 

can anyone confirm this it would make it easier

 

Looks good man... got them on my truck from the factory and love them. Its just another one of them things that makes or breaks a truck.

 

I have to go to the shop now to feed my dog. i'll check a smashed roof I've got sitting in a pile. I'll have an answer for you in an hour or so if no one else does first.

 

Nice job...Now you need clear or smoked cab lights..the ambers stick out like a sore thumb

 

Power Smoker - DUDE! That is one BADASS truck!

 

Thanks, you should see the it now, I'm making a mega cab out of it.. BTW I was wrong on the pre-stamped front bar, according to the smashed '07 cab I looked at tonight. Sorry 94yj, I guess you'll have to use the measurements rongold provided.

 

I like your grille Mr. dew the thunder, Is that one of those chinese ones you polished the grey paint off of?

 

Thanks, and no.. but I do have two stock ones that I tried and neither had the chrome under the paint. Bought that one on eBay and I guess I didn't take good enough care of it 'cause its starting to pit up and turn yellow in some areas. Probably have to get another next year.

 

Looks good man!
