Modest Improvement to a Harbor Freight Led Flashlight

I picked up a sweet little 9 led light from HF for $5 and it was kinda flaky, shake it and the light went out, so I'd thought I'd post my improvement.

The positive connection is a spring loaded pin pushing against a blob of solder. High resistance and just poor contact.

But had none on hand. So I grabbed a 4-40 nut and tinned it up.

Unscrewing the ring with the hex opening let's you remove the led module. Now just solder the hex nut to the central solder pad.

The nut makes a tight socket for the pin on the battery compartment, it also compresses the pin farther, so now no matter how hard I shake or drop it the light doesn't flake out anymore.
