Review on JWJAN 10Pcs Metal Signal Indicator Linght by Reginald Ward

I had to use a hot glue gun and "insert" the LED bulb back into the holder. They are pressed, but the dimensions are far from the same. The ad says the thread size of the holder is 6mm / 1/4 inch but they are not of those sizes. Size 17/64 was the size that best fitted the holder. And the nut on the holder has its own mysterious size. SAE or Metric, count that. It's a hex or something. I used pliers to tighten the retainer and a mini wrench to tighten the nut. The LED itself seems to be of good quality, I think time will tell how long it actually lasts.
