Fais très bien la job

The cryptic wiring diagram for the 110V model is adhered tenaciously to the body of the light. If you're wiring this yourself, the wire that's the color of the lens (red in my case) and the siren (grey) both wire to the hot (usually a black wire in the USA). The light's black wire (called "com" or "naught") wires to the neutral (usually white in the USA). It must be that "naught" is Chinglish for "neutral". There is no ground wire from the light. Once I got the light wired, I tested, and it worked. But I wanted a flashing light, not solid, so had to pull off lens and switch the DIP switch. Instead of getting intermittent flashing, I got no flashing...the first 5 times I tried. Then some connection somewhere must have scraped off its oxidation, and it started flashing, but then the siren stopped working. Several more switches back and forth, and now the light flashes and the siren works. How confident am I that this will work long term? Not very. The siren is not very loud, and the light is not very bright. I would rate this as "temporarily adequate." Let's hope the same people who make this, also make their country's weapons systems--and that their weapons systems are as reliable and confidence-inspiring as this light.
