Thank you for bringing that up DavidEF. Part of my goal with this giveaway was to encourage folks to get into modding. Lets go for April 20th. Five days after the big tax day in the USA.
Please remember to put your mod link in your first post to this thread as the OP says only the first post counts. I inadvertently created that restriction when I made the OP, but its too late now to changed the rules.
Adding an Update comment to the OP now.
7K posts, time flies 
Even though I’m in Sweden I order a bit from MTN Electronics. Good stuff and great customer service. I’m in!

Congratulations on your 7,000+ posts!
I’m afraid I’m not much of a modder. A Lego-er at the very best.
Edit: if lego-ing is good enough for you, I’ll gladly be IN!
Thank you Henk4U2. No need to be a great modder. One doesn't even have to be sucessful If you even attempt change the light in any way and post about it, you're in the drawing. Legoing is awesome and counts.
Wow, 7000 posts!
I don't think I have read through 700 posts yet.
Congrats to you sir.
That is a massive achievement! You obviously talk too much! 
One of my favourite lights, my TN30 12x Nichia 219B…

Congrats on 7000+ posts ImA! Here’s a link to one of my more interesting mods. That light is still going. It doesn’t get used a whole lot, but it doesn’t just sit on a shelf either - it sits in a drawer . . . just kidding! I think it’s still running on the original batteries though I’ve noticed it’s getting dim so they probably are run down pretty far now.

My first real in-depth mod, and probably the one that turned out the best, hehe.
Congratulations on 7k posts!
I joined BLF because what I really liked was to buy cheap lights and mod them.
In this forum I learned a lot and managed to complete my “biggest lumens small flashlight”, an ultrafire F13 with four xhp-50.
Nichia and Qlite Convoy S4:
first mod i ever did… used it to make a hollow pill “hold” a star that wouldnt fit… since i made it our of copper? it started conducting heat…
It’s funny. I know I have done and a few mods in my time here but I never seem to make any threads about them, they always seem so mundane or have already been done to make a thread about them.
Here are a few threads that could qualify, I figure I will qualify by shear volume if not by quality lol:
The bare aluminum L6, straight off the machine, from Simon Mao of Convoy! I think this is my Favorite mod I ever did or will do. From what it took to get it, during the early day’s of the L6 thread, how we shared knowledge/opinions and who made it happen (Jared), and all the unseen work, detail work, involved with this build, which most will never even notice! Like timing or indexing the battery tube, the center line is centered to the button,tactical ring centered and tail cap squared up to everything else. Or making a spacer to shim the e-switch and button up 1mm and shaving the retainer 1mm so it sits just below the surface like factory stock. Plenty of filing sanding stoning prepping and polishing, which is awful hard to do with a anodized light! 
Plus the built by hand top and bottom 17mm LD-2 driver adapter and retainer build with the uniqueness of being able to use both tail cap and e-switch to change modes!
Then being shocked at the output of the XHP70 P2-1C at 12 amps! Which has been reported to produce over 7000 lumens! :sunglasses: Normal people just see a flashlight, BLF (my) people see it as a work of ART! 
HUH 
just noticed, the Lug on the Bezel isn’t centered! :person_facepalming:
How did I miss that!
I’ll post this one, it’s a bit different than most
Red Convoy triple, with amber, red orange, and red LED’s
Photos don’t always match reality.
