Has anyone experienced a problem with intermittent connections to Surefire Scout weapon lights with Unity Hot Buttons? I have 3 M-Lok and 1 Picatinny Hot Buttons. Plugged into Surefire remote switch tail caps (UE), they all work fine. Wiggling the connection has no effect. With dual tail caps (DS00), wiggling the Hot Button connection would make the light flicker off and on. I can see the HB connector rock in the tail cap socket. Plugging Surefire switches (ST07 and SR07) into the DS00 and wiggling the connection had no effect. The SF cable connectors exhibit no rocking in the socket. The HB connectors rock only slightly on the UE tail caps. The fit is more snug than their fit in the DS00 tail cap. It is not the cable flexing. If I press the HB connector firmly sideways in the DS00 to prevent any relative movement with the socket, I could flex the cable all I wanted with no effect on the light output. |

I'll just share this - Nothing but minor issues with Surefire/ Modlites and all the switches, including the hot button. Finicky. ML's are great but until they release their own tail cap for their own switch, they are dead to me. SF to SF switch? Rarely have issues. Maybe the new SF turbos can hang with the big boys now. I think the only manufacturer doing it right is Cloud defensive. Sold all my lights, bought 4 Rein 2's. Threw in an OWL just because. All perfect, all the time. CD is king. |

Thank you for your responses. I noticed there are differences between the sockets on the SF UE and the SF DS00 tail caps. The Surefire switches mates firmly and function perfectly with either cap. The Hot Button connector seems, at least on my examples, to mate nicely without slop and function 100% with the UE tail cap. Wiggling or moving the HB connector has no effect. On the other hand, with the DS00 cap, the HB connector can wiggle and rock. With this motion, there are positions where the light flickers off then back on. I have had occasional instances where wiggling the HB connector causes the light to go dark and stay dark until wiggled more. I will contact Unity. Thanks again. |

Was a sample set of about 24 rifles having lights upgraded ( combo of Modlite and SF lights) all to hot buttons. The DS00 caps were always the culprit- I can’t remember exact number with the issues, but it was a couple. They all worked with UE caps perfectly |

I know exactly what you're talking about. For me it's just not worth the hassle. Even if it works initially, how long will that last? Why even bother with it? It's not a product that should have questions with it. |

Crazy how this was at the top of the page after experiencing this yesterday. I have a new M300 scout with the UE tail cap and a Hot Button. The scout started to flicker intermittently when activated using the button. Wiggling the connection at the cap would do it sometimes too. I unplugged/re-connected the Unity a few times and then it started working normally. The “lockup” so to speak isn’t the same as a surefire cable (SR07, etc.) and wiggles a lot more in the cap. All items (Scout, tail cap, Hot Button) were purchased together new. Cable management is fine. This is on a work gun and really pissed me off to be honest. I may just go back to using the tail cap. These items aren’t exactly cheap and I would expect them to work. I’ll try the cleaning threads/dialectic grease recommendation before changing the setup. |

For me, the Hot Button worked fine with the UE tail cap. It was the DS00 cap / Hot Button combination that gave me problems. I just tried some dielectric grease on combinations 3 Hot Buttons and 3 DS00 tail caps. It made no difference. No problems with the U# caps and flickers with all combinations of HB & DS00 caps. |

I’ve had intermittent failure to activate and flicker problems with UE tailcaps and Modbuttons and Hotbuttons. Maddeningly difficult to reproduce, just does it randomly. I’ve decided to embrace the disadvantages of tailcap activation. Anything that is not consistent or reliable is worthless to me. I tried the Rein remote switches. They work, but I’d prefer a single button, and with the way that they route over the pic rail, damage is inevitable. |
