A-Pillar Spotlight Installed Pics!

Finally installed the spotlight, had it for months. I need to wire it up and that will require taking everything apart once again. I'd go over the installation but it would take a while, if you ever purchase this spotlight I'll go over it with you on the phone rather than typing it. I nearly broke my hand when drilling into the a-pillars metal (I'll save the story for the Pismo meet, lol). It involved a 1 speed drill with MONSTER torque jamming the bit into the metal, accidentally hitting the "cruise" button, my hand is $@!%'d up.

I hardly read the instructions as they are not application specific and I heated a coat hangar, pushed it through the plastic trim to make an alignment hole. It's pretty nerving to drill a 1/2" hole into your trucks body and it's a mother drilling into flat/thick body at an angle. I'm not trying to discourage this mod but rather make one aware of what it involves, it's not a terribly difficult mod, took me a 2 1/2 hours or so and I dig the look...performance results to come tonight. Happy 4th, got front tickets with the PD to watch the fireworks!

Updated Pic!:


Onto the pics (it's a mirrored image, it's on the drivers side):




Anybody know how to determine the fuse size to use?

If that is a Unity spotlight, I think all of ours use a 20 amp fuse. IIRC, it doesn't matter if it's the 5 inch or 6 inch head, they all are 20a.

Watts divided by Volts equals amps I.E.

200W divided by 12V Equals 16.66A roughly.

That is right and that gives you what 100% max draw should be. Then multiply by 1.15 and round up to the nearest fuse size.

So, a 200W light pulls 16.66A @ 12V, which means 19.16A is 15% over current, so use a 20A fuse.

Make sense?

Thanks to the 3 of you, makes perfect sense. Here is a night shot for your replies. I'm thrilled with it, pretty bright.

By the way, what is the best way to prevent rust/corrosion on these drilled holes. Is rust a certainty if nothing is done to prevent? Those are stock headlights in the image above with fogs on as well.

RE: Rust - maybe a nice coating of Rustoleam under the housing - applied with a small applicator brush and then waxed to seal?

Can you please take a close up of the housing (or hole) on the A-pillar?
Also, what is the range of motion on the light itself? Are you able to move it rather easily from a "resting" position to an upright position?
Finally, can we get a shot from inside the cab with the light at "rest"?

Thanks!! (Sorry for all the questions!)

Get some zinc based primer to coat the bare metal with. You can put matching paint over top of that if you want but you definitely want to cover that bare metal.
