I had before me a wx150, an incandescent M3X and a countoured pressure switch by insight also. The only difference I could see between the lights tailcaps were the M3X was little thicker. I know a rep for the company and I know they don’t offer the contoured switch for the WX150. I also spoke with a customer service lady on the phone today about it and she told they aren’t going to. A little dremeling later and VOILA! A WX150 with a contoured pressure switch. If a guy with a dremel in his garage can do it, why can’t insight? All I did was remove material because the pressure switch has a slightly larger thickness. I also removed the clasp from the pressure switch and dremeled a flat part for the WX150’s clasp. It still isn’t a perfect fit but it works. I can’t believe I spent $100 on the switch just to do this… Anyway, double tapping and holding on the second tap will activate the strobe.
