Introduction: Modest Improvement to a Harbor Freight Led Flashlight

By
About: Working my dream job in the Telecom industry, so chances are, i'll never have time to respond to comments or messages, nothing personal.

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.

Step 1: What's the Problem

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

Step 2: I Had Thought to Just Use a Mini Connector

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

Step 3: Disassemble the Flashlight.

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.

Step 4: Okay

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.
