Make your own 3M sun gun. total cost if you have to buy everything 40 bucks
following info found on google, this is what I did, but I bought a 20 dollar 12 volt drill at wall mart but used same light and connector. I would actually get a narrower beamed light for my next one I am gonna build. Ill tell you what this thing will light up my back yard like mad. If you want the pics just google DIY 3M sun gun.
10% of the original cost of a 3M sun Gun I have the exact same thing except I had the fun of building it myself lol
Its a cordless light that is widely known to the detailing community to be the best swirl finder money can buy,
Sadly these little buggers come with quite the price tag,
The retail on them is around $400,
To me that is ludicrous for a light,
So I decided to make my own following various other detailing enthusiasts ideas,
So where to start,
Well Firstly you need a 12v Cordless Drill, and 12v is very important,
18v is too high for the bulb, 14.4 is ok but 12 is ideal,
So First you need the 12v Drill,
Then you need the exact same bulb that's in the 3M gun,
The Solux 4700K Daytime light,
Then you need a holder for this light and then its pretty much plug and play,
I'll walk you through my steps,
First the drill,
a wonderful absolutely nothing wrong with run of the mill 12v Skil Drill,
(even came with its own case)
Next the Solux bulb and connector,
After which you open the drill,
and then take out the motor and chuck,
Test fit the bulb in the chucks grooves,
and wire the 2 very simple wires that come from the trigger to the bulb connector
Of course now would be a good time to test it before you put it back together,
Great!
Now simply put the case back together and your left with something that should look like this
and it fits nice back in its case with room even for a spare bulb!
